    ________________________________
    Kisha Loomis brought suit against Amazon.com LLC
    (Amazon) for injuries she suffered from an allegedly defective
    hoverboard. The hoverboard was sold by a third party seller
    named TurnUpUp through the Amazon website. The trial court
    granted summary judgment in favor of Amazon. The primary
    issue on appeal is whether Amazon may be held strictly liable for
    Loomis’s injuries from the defective product. Recently, the
    Fourth District addressed this issue as a matter of first
    impression in Bolger v. Amazon.com, LLC (2020) 
    53 Cal. App. 5th 431
    (Bolger), review denied November 18, 2020. Bolger held
    Amazon “is an ‘integral part of the overall producing and
    marketing enterprise that should bear the cost of injuries
    resulting from defective products.’ ” (Id. at p. 453.) Our own
    review of California law on strict products liability persuades us
    that Bolger was correctly decided and that strict liability may
    attach under the circumstances of this case. We reverse and
    remand with directions.
    I. FACTS
    Loomis ordered a hoverboard on Amazon’s website on
    November 28, 2015. The listing identified the seller to be
    TurnUpUp, a name used by SMILETO to sell its products on
    Amazon’s marketplace. SMILETO is allegedly a company based
    in China. The hoverboard was shipped to Loomis by Forrinx
    Technology (USA), Inc. Loomis was notified by Amazon that the
    product shipped on December 1, 2015. On December 11, 2015,
    Loomis sent an e-mail inquiring whether the hoverboard would
    be delivered in time for Christmas. The e-mail was sent through
    Amazon’s website. Loomis received the hoverboard on December
    16, 2015. Loomis gifted the hoverboard to her son. On New
    Year’s Eve, he plugged it into an outlet in Loomis’s bedroom to
    2
    charge. Loomis’s boyfriend later discovered a fire burning in her
    bedroom. Her bed and the hoverboard were on fire. Loomis
    suffered burns to her hand and foot as a result of fighting the fire.
    A. Third Party Sales on Amazon.com
    Amazon.com is an online marketplace where Amazon and
    third party sellers list their products for sale. Amazon describes
    its marketplace as “an online mall” which provides an “online
    storefront” to third party sellers. Where Amazon is the seller of a
    product, it is identified as the seller on the product detail page,
    and it sources the product, sets the price, and holds title to it.
    This case does not involve an Amazon-listed product. Where a
    third party is the seller, it is identified as such on the product
    detail page and again on the order confirmation page before the
    user places the order. The third party sources the product, sets
    the price, and holds title to it.
    All third party sellers operate under the Amazon Services
    Business Solutions Agreement (BSA). The BSA requires a seller
    to “ensure that [it is] the seller of each of [its] Products” and to
    provide Amazon with accurate, updated product information in a
    specified format. A third party seller chooses what products to
    sell and at what price. However, the BSA requires pricing parity,
    where the price is “at least as favorable to Amazon Site users as
    the most favorable terms” offered by the seller elsewhere.
    Amazon provides payment processing for all third party
    sales. It remits the purchase price to the third party seller on a
    set schedule minus any service fees it may charge. Amazon
    collects a “referral fee,” a percentage of the sale price per item
    sold by the third-party seller, depending on the nature of the item
    sold. For toys, such as hoverboards, the referral fee is 15 percent
    of the sale price. The seller is required to route all payments and
    3
    refunds through Amazon, who may withhold payments,
    sometimes permanently, from the seller based upon its
    investigation of any disputes or claims. Refunds due to
    purchasers are calculated by the seller according to Amazon’s
    refund policies and routed through Amazon. The BSA further
    required all communications between the seller and buyer to be
    made through Amazon.
    Under the BSA, Amazon expressly reserves the right to
    control of its website and listings: “We have the right in our sole
    discretion to determine the content, appearance, design,
    functionality and all other aspects of the Amazon Sites, including
    by redesigning, modifying, removing or restricting access to any
    of them, and by suspending, prohibiting or removing any listing.”
    The BSA also allows Amazon in its sole discretion to refuse to
    process or cancel any transactions.
    The seller must also ensure its materials, products, offers
    and sales comply with all applicable laws. The BSA advises third
    party sellers they are “responsible for any non-conformity or
    defect in, or any public or private recall of, any of [their] Products
    or other products provided in connection with [the] Products.” In
    addition to Amazon’s own efforts to monitor recalls, the BSA
    requires third party sellers to notify Amazon “promptly” of any
    public or private recalls of their products.
    Sellers also agree to indemnify Amazon from any liability
    arising from its products. For those sellers whose gross proceeds
    exceed a specified threshold, which was applicable to TurnUpUp,
    the BSA also requires them to acquire excess insurance naming
    Amazon as an additional insured.
    Some third party sellers utilize Fulfillment by Amazon
    (FBA) services, which allow the seller to store its inventory in an
    4
    Amazon warehouse. If a product is sold under the FBA, Amazon
    packages and ships the product to the purchaser. TurnUpUp did
    not elect to utilize the FBA services.
    Amazon provides purchasers with what it calls an “A-to-z
    Guarantee:” “We want you to buy with confidence any time you
    make a purchase on the Amazon.com Website or use Amazon
    Pay. . . . The condition of the item you buy and its timely delivery
    are guaranteed under the unconditional A-to-z Guarantee.”
    Amazon, however, does not consider the A-to-z Guarantee to
    constitute a warranty for the products it lists. It instead warns
    purchasers in its Conditions of Use that third parties sell
    products through Amazon and that Amazon is “not responsible
    for examining or evaluating, and [does] not warrant, the offerings
    of any of these businesses or individuals . . . . Amazon does not
    assume any responsibility or liability for the actions, product, and
    content of all these and any other third parties.”
    B. The Sale of Hoverboards on Amazon
    More than 380,000 hoverboards were purchased through
    Amazon in 2015. The vast majority were sold by third party
    sellers. Under the BSA, Amazon charged TurnUpUp various fees
    for its services, including a $39.99 monthly nonrefundable
    subscription fee and a 15 percent referral fee that was calculated
    from the total sales price of each product. For the transaction at
    issue, Amazon received a referral fee of $55.50 from the $370 sale
    of the TurnUpUp hoverboard to Loomis. For the period between
    September 14, 2015, and December 16, 2015, TurnUpUp sold
    hoverboards totaling $736,366.68 through Amazon. Amazon
    received $110,645.92 in fees from those sales.
    In late November 2015, Amazon’s product safety team
    began investigating hoverboards in response to press reports that
    5
    hoverboards were involved in fires. It identified 17 reports of fire
    or smoke allegedly caused by hoverboards sold through Amazon.
    These 17 reports involved different models and manufacturers.
    On December 10, 2015, Amazon decided to remove all third
    party hoverboard listings from its website. It sent all prior
    hoverboard purchasers an e-mail notifying them of the reports of
    safety problems with hoverboards. Loomis testified in her
    deposition she did not recall receiving such an e-mail from
    Amazon.
    During this time, the Consumer Product Safety
    Commission (CPSC) conducted its own investigation into
    hoverboard safety and was in contact with Amazon about it. On
    February 18, 2016, the CPSC issued a letter stating that it
    regarded hoverboards that do not comply with a draft
    Underwriters Laboratories voluntary standard as presenting a
    potential “substantial product hazard.” The CPSC announced
    recalls of certain hoverboard models in July 2016.
    C. The Legal Proceedings
    Loomis brought suit against Forrinx1 and Doe defendants
    for products liability and fraud on September 2, 2016. In a form
    complaint, Loomis alleged three “counts” related to the product
    liability cause of action. Count one alleged strict products
    liability, count two alleged negligence, and count three alleged a
    breach of warranty. Loomis later amended her complaint to
    substitute Amazon into the lawsuit for a Doe defendant.
    Amazon moved for summary judgment on a number of
    grounds, including that it did not fall within the chain
    1     Forrinx failed to appear and a default was entered against
    it.
    6
    of distribution for product liability purposes, it could not be liable
    under the “marketing enterprise theory” for those entities that
    fell outside the chain of distribution, and the federal
    Communications Decency Act (47 U.S.C. § 230) (CDA) barred
    Loomis’s claims.2 The trial court granted Amazon’s motion for
    summary judgment. Loomis timely appealed.
    II. DISCUSSION
    At issue in this appeal are Loomis’s strict and negligent
    product liability claims.3 She contends summary adjudication
    was improperly granted due to Amazon’s participation in the
    vertical chain of distribution for the product. Amazon disclaims
    any liability on the ground it is neither a manufacturer nor seller
    of the hoverboard. We conclude there exist triable issues of
    2     Under the CDA, “[n]o provider or user of an interactive
    computer service shall be treated as the publisher or speaker of
    any information provided by another information content
    provider.” (47 U.S.C. § 230 (c)(1).) “No cause of action may be
    brought and no liability may be imposed under any State or local
    law that is inconsistent with this section.” (Id., (e)(3).)
    3     Loomis acknowledges her fraud claim (second cause of
    action) and breach of warranty claim (count three of the first
    cause of action) are not at issue in this appeal. In the
    respondent’s brief, Amazon informed us that we need not
    address its CDA-based arguments as “[Loomis] has abandoned
    her fraud claim and frames her remaining claims as based solely
    on Amazon’s role in the transaction, not on the website’s content.”
    We understand this statement to mean Amazon concedes the
    CDA only applied to shield it from Loomis’s fraud claim and not
    her strict liability and negligence claims. Accordingly, we agree
    we need not address whether the CDA provides immunity to
    Amazon from the strict liability and negligence claims.
    7
    material fact which warrant reversal of summary adjudication as
    to these claims.4
    A. Standard of Review
    A defendant moving for summary judgment must show
    that one or more elements of a cause of action cannot be
    established or that there is a complete defense to the cause of
    action. (Code Civ. Proc., § 437c, subd. (p)(2); Miller v. Department
    of Corrections (2005) 
    36 Cal. 4th 446
    , 460.) Once the defendant’s
    burden has been met, the plaintiff is required to show a triable
    issue of material fact as to the cause of action or defense. (Code
    Civ. Proc., § 437c, subd. (p)(2).) A triable issue of fact is created
    when the evidence reasonably permits the trier of fact, under the
    applicable standard of proof, to find the purportedly contested
    fact in favor of the party opposing the motion. (Lugtu v.
    California Highway Patrol (2001) 
    26 Cal. 4th 703
    , 722.) The
    plaintiff may not rely on the allegations in her pleadings but
    must set forth the specific facts showing the triable issue. (Code
    Civ. Proc., § 437c, subd. (p)(2).)
    We review the record de novo, considering all the evidence
    set forth in the moving and opposing papers except that to which
    4      Loomis also contends her claim for punitive damages
    survives summary adjudication because her products liability
    claims do. Amazon does not address this issue in its respondent’s
    brief. Below, it sought summary adjudication of punitive
    damages on the ground Loomis had no viable underlying claims
    to support it. It presented no argument as to the merits of the
    claim. Loomis is correct that a punitive damages award may
    properly be entered in a strict products liability suit. (Grimshaw
    v. Ford Motor Co. (1981) 
    119 Cal. App. 3d 757
    , 807-808,
    disapproved on a different ground by Kim v. Toyota Motor Corp.
    (2018) 
    6 Cal. 5th 21
    .)
    8
    objections were made and sustained. We liberally construe the
    evidence in support of the plaintiff opposing summary judgment
    and resolve doubts concerning the evidence in her favor. (Code
    Civ. Proc. § 437c, subd. (c); Yanowitz v. L’Oreal USA, Inc. (2005)
    
    36 Cal. 4th 1028
    , 1037; AARTS Productions, Inc. v. Crocker
    National Bank (1986) 
    179 Cal. App. 3d 1061
    , 1064–1065.)
    B. The Doctrine of Strict Products Liability in
    California
    Greenman v. Yuba Power Products, Inc. (1963) 
    59 Cal. 2d 57
    , 62 (Greenman) established the doctrine of strict products
    liability when it held “[a] manufacturer is strictly liable in tort
    when an article he places on the market, knowing that it is to be
    used without inspection for defects, proves to have a defect that
    causes injury to a human being.” “The purpose of such liability is
    to insure that the costs of injuries resulting from defective
    products are borne by the manufacturers that put such products
    on the market rather than by the injured persons who are
    powerless to protect themselves.” (Id. at p. 63.)
    The California Supreme Court extended the doctrine to
    retailers in Vandermark v. Ford Motor Co. (1964) 
    61 Cal. 2d 256
    (Vandermark), reasoning, “Retailers like manufacturers are
    engaged in the business of distributing goods to the public. They
    are an integral part of the overall producing and marketing
    enterprise that should bear the cost of injuries resulting from
    defective products. [Citation.] In some cases the retailer may be
    the only member of that enterprise reasonably available to the
    injured plaintiff. In other cases the retailer himself may play a
    substantial part in insuring that the product is safe or may be in
    a position to exert pressure on the manufacturer to that end; the
    retailer’s strict liability thus serves as an added incentive to
    9
    safety. Strict liability on the manufacturer and retailer alike
    affords maximum protection to the injured plaintiff and works no
    injustice to the defendants, for they can adjust the costs of such
    protection between them in the course of their continuing
    business relationship.” (Id. at pp. 262-263.)
    California courts must consider the policies underlying the
    doctrine to determine whether to extend strict liability in a
    particular circumstance. (Anderson v. Owens–Corning Fiberglas
    Corp. (1991) 
    53 Cal. 3d 987
    , 995 (Anderson); O’Neil v. Crane Co.
    (2012) 
    53 Cal. 4th 335
    , 362–363 (O’Neil).) The public policies
    articulated in Greenman and Vandermark that form the
    foundation for the application of strict liability are the following:
    (1) whether Amazon may play a substantial part in insuring that
    the product is safe or may be in a position to exert pressure on
    the manufacturer to that end, (2) whether Amazon may be the
    only member in the distribution chain reasonably available to the
    injured plaintiff, and (3) whether Amazon is in a position to
    adjust the costs of compensating the injured plaintiff amongst
    various members in the distribution chain. 
    (Vandermark, supra
    ,
    61 Cal.2d at pp. 262-263.)
    Applying these policy considerations, courts have extended
    strict products liability to entities within the chain of
    distribution, including bailors and lessors (Price v. Shell Oil
    Company (1970) 
    2 Cal. 3d 245
    , 248); wholesalers and distributors
    (Barth v. B. F. Goodrich Tire Co. (1968) 
    265 Cal. App. 2d 228
    , 252-
    253; Canifax v. Hercules Powder Co. (1965) 
    237 Cal. App. 2d 44
    , 52
    (Canifax)); and sellers of mass-produced homes (Kriegler v.
    Eichler Homes, Inc. (1969) 
    269 Cal. App. 2d 224
    , 227). Courts
    have found these defendants were responsible for passing the
    product down the line to the consumer, had the ability to affect
    10
    product safety by exerting pressure on the manufacturer, and
    were able to bear the cost of compensating for injuries. (Arriaga
    v. CitiCapital Commercial Corp. (2008) 
    167 Cal. App. 4th 1527
    ,
    1535 (Arriaga).) Courts, however, have declined to extend the
    doctrine to hotel proprietors (Peterson v. Superior Court (1995) 
    10 Cal. 4th 1185
    ); sellers of used products (Wilkinson v. Hicks (1981)
    
    126 Cal. App. 3d 515
    ); and auctioneers (Tauber–Arons Auctioneers
    Co. v. Superior Court (1980) 
    101 Cal. App. 3d 268
    (Tauber-Arons)),
    who were found to have little to no relationship with the
    manufacturer and thus lacked the ability to affect product safety.
    A consumer injured by a defective product “may now sue
    ‘any business entity in the chain of production and marketing,
    from the original manufacturer down through the distributor and
    wholesaler to the retailer; liability of all such defendants is joint
    and several.’ ” (Wimberly v. Derby Cycle Corp. (1997) 
    56 Cal. App. 4th 618
    , 628.) The purpose for this approach “is to
    extend liability to all those engaged in the overall producing and
    marketing enterprise who should bear the social cost of the
    marketing of defective products.” (Kaminski v. Western
    MacArthur Co. (1985) 
    175 Cal. App. 3d 445
    , 455-456.)
    “The strict liability doctrine derives from judicially
    perceived public policy considerations, i.e., enhancing product
    safety, maximizing protection to the injured plaintiff, and
    apportioning costs among the defendants. [Citations.] Where
    these policy justifications are not applicable, the courts have
    refused to hold the defendant strictly liable even if that
    defendant could technically be viewed as a ‘ “link in the chain” ’
    in getting the product to the consumer market. [Citation.] In
    other words, the facts must establish a sufficient causative
    relationship or connection between the defendant and the product
    11
    so as to satisfy the policies underlying the strict liability
    doctrine.” 
    (Arriaga, supra
    , 167 Cal.App.4th at p. 1535.)
    The court in Bay Summit Community Assn. v. Shell Oil Co.
    (1996) 
    51 Cal. App. 4th 762
    (Bay Summit), set forth three factors
    to determine whether such a causative relationship or connection
    exists when the defendant falls outside the vertical chain of
    distribution. Under the marketing enterprise theory or stream of
    commerce approach, the plaintiff must show: “(1) the defendant
    received a direct financial benefit from its activities and from the
    sale of the product; (2) the defendant’s role was integral to the
    business enterprise such that the defendant’s conduct was a
    necessary factor in bringing the product to the initial consumer
    market; and (3) the defendant had control over, or a substantial
    ability to influence, the manufacturing or distribution process.”
    (Id. at p.776; Kasel v. Remington Arms Co. (1972) 
    24 Cal. App. 3d 711
    (Kasel).)
    C. Bolger v. Amazon.com LLC
    In Bolger, the Fourth District applied strict products
    liability analysis to substantially identical facts as presented in
    this case. There, the plaintiff bought a replacement battery for
    her laptop from a third party seller through the Amazon website.
    The battery allegedly exploded several months later, causing
    severe burns. 
    (Bolger, supra
    , 53 Cal.App.5th at p. 437.) The trial
    court granted summary judgment in favor of Amazon on the
    ground it did not distribute, manufacture, or sell the product in
    question. The Fourth District reversed. (Id. at p. 439.)
    The Bolger court found Amazon was “a direct link in the
    chain of distribution, acting as a powerful intermediary between
    the third party seller and the consumer.” 
    (Bolger, supra
    , 53
    Cal.App.5th at p. 438.) “As a factual and legal matter, Amazon
    12
    placed itself between [the seller] and Bolger in the chain of
    distribution of the product at issue here. Amazon accepted
    possession of the product from [the seller], stored it in an Amazon
    warehouse, attracted Bolger to the Amazon website, provided her
    with a product listing for [the seller’s] product, received her
    payment for the product, and shipped the product in Amazon
    packaging to her. Amazon set the terms of its relationship with
    [the seller], controlled the conditions of [the seller’s] offer for sale
    on Amazon, limited [the seller’s] access to Amazon’s customer
    information, forced [the seller] to communicate with customers
    through Amazon, and demanded indemnification as well as
    substantial fees on each purchase. Whatever term we use to
    describe Amazon’s role, be it ‘retailer,’ ‘distributor,’ or merely
    ‘facilitator,’ it was pivotal in bringing the product here to the
    consumer.” (Ibid.)
    After concluding Amazon was a link in the chain of
    distribution, the Bolger court found the policies articulated in
    Greenman, Vandermark, and their progeny supported imposition
    of strict liability. The court found Amazon was the only member
    of the enterprise reasonably available to an injured consumer in
    some cases, it played a substantial part in ensuring the products
    listed on its website were safe, it could and did exert pressure on
    upstream distributors like the instant seller to enhance safety,
    and it had the ability to adjust the cost of liability between itself
    and its third party sellers. The court concluded Amazon should
    be held liable if a product sold through its website turned out to
    be defective, since strict liability in the instant case afforded
    maximum protection to the injured plaintiff and worked no
    injustice to Amazon. 
    (Bolger, supra
    , 53 Cal.App.5th at pp. 453-
    455.)
    13
    In Bolger, Amazon presented many of the same arguments
    to disclaim liability as it does in this case. 
    (Bolger, supra
    , 53
    Cal.App.5th at pp. 455-458.) The court rejected each of these
    arguments.
    Amazon initially focused on dictionary or Commercial Code
    definitions of “seller” and “distributor” to argue those definitions
    did not apply to it. It asserted it was a service provider that was
    not subject to strict liability and that had no control over the
    selection of the product or its pricing. 
    (Bolger, supra
    , 53
    Cal.App.5th at p. 456.)
    The court explained strict products liability was created
    judicially because of the economic and social need for the
    protection of consumers in an increasingly complex and
    mechanized society. The scope of strict liability was expanded
    when necessary to account for market realities and to cover new
    transactions, such as this one, in widespread use in today’s
    business world regardless of labels or dictionary definitions.
    
    (Bolger, supra
    , 53 Cal.App.5th at p. 456.)
    The court rejected Amazon’s assertion it was merely a
    service provider with no control over the product. It held,
    “Nothing aside from Amazon’s own choices required it to allow
    [the seller] to offer its product for sale, to store [the seller’s]
    product at its warehouse, to accept Bolger’s order, or to ship the
    product to her. It made these choices for its own commercial
    purposes. It should share in the consequences.” 
    (Bolger, supra
    ,
    53 Cal.App.5th at p. 457.) The court concluded Amazon’s control
    over both the product and the sales transaction formed the basis
    for its liability. (Id. at pp. 458-459.)
    Additionally, Amazon argued, as it does here, that the
    Legislature, not the court, was the appropriate forum to address
    14
    whether those policies would be served in new contexts. The
    Bolger court found this argument ran “directly contrary to
    California law” on strict liability, which was created by the courts
    and expanded and contracted where warranted by its purposes.
    
    (Bolger, supra
    , 53 Cal.App.5th at p. 459.)
    Lastly, the court found the federal CDA did not shield
    Amazon from strict liability because liability was based on
    Amazon’s own conduct, not the content of the seller’s product
    listing. 
    (Bolger, supra
    , 53 Cal.App.5th at p. 465.)
    Amazon contends Bolger was erroneously decided because
    it ignores long-standing limitations on strict liability law.
    According to Amazon, these long-standing limitations include a
    “threshold requirement” for strict liability expressed in O’Neil
    and case law excluding service providers from strict liability. We
    explain below (post, sec. D,3) how Amazon has misinterpreted
    O’Neil and the cases regarding liability of service providers.
    We are also not persuaded by Amazon’s argument that
    Bolger improperly applied strict liability to “facilitators.”
    Amazon argues, “Before the Fourth District’s Bolger decision, the
    lower courts uniformly . . . rejected claims against service
    providers that facilitated, or were even necessary to consummate,
    sales.” In each of those cases, however, the courts did not refuse
    to impose strict liability simply because the defendant facilitated
    a sale. The courts each examined the underlying policies and
    determined strict liability as to finance lessors and auctioneers
    was not appropriate. 
    (Arriaga, supra
    , 167 Cal.App.4th at p. 1537
    [“The policy considerations behind imposing strict products
    liability on those involved in the vertical distribution of consumer
    goods are not furthered by including finance lessors.” (Italics
    omitted.)]; 
    Tauber-Arons, supra
    , 101 Cal.App.3d at p. 274 [“The
    15
    real issue in this case is whether the policy of the doctrine of
    strict liability established by the decisions of the appellate courts
    in this state justifies the imposition of strict liability under such
    circumstances.”]; Brejcha v. Wilson Machinery, Inc. (1984) 
    160 Cal. App. 3d 630
    [relying on Tauber-Arons].)
    Amazon next criticizes Bolger for relying on “vague and ill-
    defined policy notions” that were “cited six decades ago.” As
    Bolger observed, this argument directly conflicts with the
    Supreme Court’s repeated observation that “[t]he question
    whether to apply strict liability in a new setting is largely
    determined by the policies underlying the doctrine.” 
    (O’Neil, supra
    , 53 Cal.4th at pp. 362–363; 
    Anderson, supra
    , 53 Cal.3d at
    p. 995; see also Bay 
    Summit, supra
    , 51 Cal.App.4th at p. 774.)
    We conclude Bolger has properly applied well-established strict
    liability law to the facts of its case and was correctly decided.
    D. Analysis
    1. Vertical Chain of Distribution
    As technology advances, innovation is paving the way to
    new business practices. Amazon is on the leading edge of e-
    commerce. Based on our review of Amazon’s third-party business
    model under the BSA, we are persuaded that Amazon’s own
    business practices make it a direct link in the vertical chain of
    distribution under California’s strict liability doctrine.
    Contrary to Amazon’s assertion that it merely provided an
    online storefront for TurnUpUp and others to sell their wares, it
    is undisputed Amazon placed itself squarely between TurnUpUp,
    the seller, and Loomis, the buyer, in the transaction at issue.
    When Loomis wanted to buy a hoverboard for her son, she
    perused product listings on Amazon’s website. Amazon took
    Loomis’s order and processed her payment. It then transmitted
    16
    the order to TurnUpUp, who packaged and shipped the product
    to Loomis.
    When Loomis wondered whether the hoverboard would
    arrive in time for Christmas, she communicated her concerns
    through Amazon. TurnUpUp was not allowed to communicate
    with Loomis directly. If Loomis had wanted to return the
    hoverboard, the return would have been routed through Amazon.
    Amazon remitted Loomis’s payment to TurnUpUp after
    deducting its fees, including a 15 percent referral fee based on the
    total sale price. These facts undermine Amazon’s
    characterization of its marketplace as an online mall providing
    online storefronts for sellers. Owners of malls typically do not
    serve as conduits for payment and communication in each
    transaction between a buyer and a seller. Moreover, they do not
    typically charge a per-item fee rather than a fixed amount to rent
    their storefronts. Instead, these actions – 1) interacting with the
    customer, 2) taking the order, 3) processing the order to the third
    party seller, 4) collecting the money, and 5) being paid a
    percentage of the sale – are consistent with a retailer or a
    distributor of consumer goods.
    2. Stream of Commerce Approach
    Although we conclude Amazon is a link in the vertical
    chain of distribution, we nevertheless recognize e-commerce may
    not neatly fit into a traditional sales structure. The stream of
    commerce approach or market enterprise theory offers an
    alternative basis for strict liability.
    “[U]nder the stream-of-commerce approach to strict
    liability no precise legal relationship to the member of the
    enterprise causing the defect to be manufactured or to the
    member most closely connected with the customer is required
    17
    before the courts will impose strict liability. It is the defendant’s
    participatory connection, for his personal profit or other benefit,
    with the injury-producing product and with the enterprise that
    created consumer demand for and reliance upon the product (and
    not the defendant’s legal relationship (such as agency) with the
    manufacturer or other entities involved in the manufacturing-
    marketing system) which calls for imposition of strict liability.
    [Citation.]” (Kasel , supra, 24 Cal.App.3d at p. 725.) Thus, a
    defendant may be strictly liable under the stream of commerce
    approach if: “(1) the defendant received a direct financial benefit
    from its activities and from the sale of the product; (2) the
    defendant’s role was integral to the business enterprise such that
    the defendant’s conduct was a necessary factor in bringing the
    product to the initial consumer market; and (3) the defendant
    had control over, or a substantial ability to influence, the
    manufacturing or distribution process.” (Bay 
    Summit, supra
    , 51
    Cal.App.4th at p. 778.)
    Viewing the evidence in the light most favorable to Loomis,
    there exists a triable issue of material fact as to each of the three
    factors identified above. First, Amazon does not dispute it
    received a direct financial benefit in the form of fees, including a
    monthly subscription fee and a 15 percent referral fee, from the
    sale of the product. However, it contends the fees it charges must
    also be connected to its activities in bringing the product to the
    initial consumer market. (Bay 
    Summit, supra
    , 51 Cal.App.4th at
    p. 776 [“Shell directly profited from its activities in creating a
    market for the polybutylene plumbing system and from each sale
    of the plumbing system.”].) It argues it has engaged in no such
    activities, and has derived no financial benefit, because the
    market for hoverboards existed regardless of Amazon.
    18
    Contrary to Amazon’s broad interpretation of what
    constitutes “the initial consumer market,” caselaw tells us “the
    relevant market in which the defendant was deemed a
    participant was the initial distribution to the consuming public of
    the particular defective product of a given manufacturer,” “not
    just products of the same classification.” (
    Tauber-Arons, supra
    ,
    101 Cal.App.3d at p. 276; see also 
    Kasel, supra
    , 24 Cal.App.3d at
    p. 725 [defendant’s participation in the enterprise which
    distributed and created consumer demand for “Remington
    Express” shot shells]; Bay 
    Summit, supra
    , 51 Cal.App.4th at p.
    776 [polybutylene plumbing system].) Therefore, we need to
    determine whether Amazon received a direct financial benefit
    from its activities to bring TurnUpUp hoverboards to market.
    To this end, Amazon presented no evidence that it did not
    play a role in establishing a market for TurnUpUp hoverboards.
    Instead, it presented testimony that it had no information what
    other sales channels TurnUpUp used to sell its hoverboards. By
    contrast, the evidence shows Amazon received $110,645.92 from
    its sale of TurnUpUp hoverboards from September 14, 2015 to
    December 16, 2015. At a minimum, this evidence creates a
    triable issue of material fact as to whether Amazon received a
    direct financial benefit from its activities and sales of the product.
    For the same reason, there exists a triable issue with
    respect to the second factor—whether Amazon’s role was integral
    to the business enterprise. Amazon has failed to meet its burden
    to demonstrate this factor cannot be established because it has
    presented no evidence of its role in bringing TurnUpUp’s
    hoverboards to market.
    Third, the record demonstrates Amazon had substantial
    ability to influence the manufacturing or distribution process
    19
    through its ability to require safety certification, indemnification,
    and insurance before it agrees to list any product. For example,
    the BSA allows Amazon to require certification of products it lists
    from the Underwriter’s Laboratories, which, among other things,
    establishes standards for manufacturing practices. Amazon’s
    contention that it has no relationship with the manufacturer or
    the distributors has no bearing on whether it can influence the
    manufacturing process.
    We are persuaded the trial court erroneously granted
    summary adjudication on the strict liability claim based on a
    stream of commerce approach.
    3. Service Provider
    Amazon disputes it plays a role in the vertical distribution
    chain or the stream of commerce because it is not a
    manufacturer, seller, or supplier, but merely a service provider.
    It seizes on a single sentence in O’Neil to create a “threshold
    requirement” for the imposition of strict liability. The sentence
    in O’Neil reads: “That the defendant manufactured, sold, or
    supplied the injury-causing product is a separate and threshold
    requirement that must be independently established.” 
    (O’Neil, supra
    , 53 Cal.4th at p. 362.) Amazon would have us interpret
    that sentence in O’Neil to limit strict liability only to
    manufacturers, sellers, and suppliers. Read in context, however,
    it is clear O’Neil did not intend to overturn five decades of case
    law extending strict liability to lessors, bailors, and others within
    the stream of commerce who may not bear the label of
    manufacturer, seller, or supplier. (See, e.g., Fortman v. Hemco,
    Inc. (1989) 
    211 Cal. App. 3d 241
    , 251 [“entities in the stream of
    commerce for purposes of strict liability are not limited to those
    20
    readily identifiable as designer, manufacturer, or vendor of the
    defective product”].)
    In O’Neil, the plaintiff sought to impose strict liability on a
    manufacturer who supplied a nondefective part that was later
    used with a defective product that caused injury. By this
    sentence, the high court merely indicated an innocent
    manufacturer may not be held strictly liable for a defective
    product made, sold, or supplied by someone else. 
    (O’Neil, supra
    ,
    53 Cal.4th at p. 362.)
    We likewise reject Amazon’s argument it is merely a
    service provider who is not subject to strict products liability. We
    have identified how it was instrumental in the sale of the
    hoverboard to Loomis.
    Even if Amazon may be characterized as a service provider,
    Murphy v. E. R. Squibb & Sons, Inc. (1985) 
    40 Cal. 3d 672
    (Murphy) and Hernandezcueva v. E.F. Brady Co., Inc. (2015) 
    243 Cal. App. 4th 249
    (Hernandezcueva), cited by Amazon, are
    instructive on the issue of when strict liability attaches to service
    providers.
    In both cases, the court determined the defendant provided
    both a service and sale of a product. Therefore, “[t]he propriety of
    imposing strict liability on a party that both supplies and installs
    a defective component hinges on the circumstances of the
    transaction.” 
    (Hernandezcueva, supra
    , 243 Cal.App.4th at p.
    260.) In Murphy, the court determined the service aspect of the
    defendant pharmacist’s role predominated over its sale of
    prescription drugs. 
    (Murphy, supra
    , 40 Cal.3d at p. 675.) In
    Hernandezcueva, the court determined the subcontractor that
    installed drywall in a commercial project provided both a service
    (the installation) and the sale of a product (the drywall). Despite
    21
    its dual role, the subcontractor was a participant in the stream of
    commerce for strict liability purposes. 
    (Hernandezcueva, supra
    ,
    at p. 263.)
    Here, Amazon provides a service to TurnUpUp in the form
    of a website to list its product and, as described above, was also
    instrumental in the sale of the product by placing itself squarely
    between TurnUpUp and Loomis. That it did not hold title to the
    product and did not have physical possession of the hoverboard
    does not automatically render it solely a service provider and
    remove it from strict liability. 
    Canifax, supra
    , 
    237 Cal. App. 2d 44
    is instructive on this issue.
    In Canifax, the customer purchased the defective fuse (and
    related supplies) from a jobber, who in turn placed an order with
    the defendant, who passed on the order for the fuse to the
    manufacturer. The manufacturer shipped the fuse directly to the
    jobber and the defendant paid the manufacturer from the
    proceeds it received from the jobber. (
    Canifax, supra
    , 
    237 Cal. App. 2d 44
    at p. 48.) The defendant disputed strict liability
    on the basis it did not manufacture the fuse, sell the fuse, and
    never had possession of the fuse. The court held, “The fact that it
    chooses to delegate the manufacture of [the] fuse to another and
    that it causes the manufacturer to ship the product directly to the
    consumer cannot be an escape hatch to avoid liability.” (Id. at p.
    52.)
    The circumstances surrounding the sale of the hoverboard
    are materially similar to those surrounding the sale of the fuse in
    Canifax. As in Canifax, Amazon did not manufacture the
    hoverboard, did not sell the hoverboard, and never had physical
    possession of the hoverboard. These facts, however, “cannot be
    an escape hatch to avoid [strict] liability.” (
    Canifax, supra
    ,
    22
    237 Cal.App.2d at p. 52.) This is because, like the defendant in
    Canifax, Amazon took the order for the hoverboard, took the
    payment, and passed the order up the chain of distribution. (Id.
    at p. 50.)
    4. Out-of-State Cases
    We are not persuaded by Amazon’s reliance on those
    decisions that restrict strict liability to sellers or manufacturers
    by applying out-of-state law. (Erie Ins. Co. v. Amazon.com, Inc.
    (4th Cir. 2019) 
    925 F.3d 135
    , 140 [“products liability under
    Maryland law. . . is imposed on sellers and manufacturers (a
    manufacturer also being a seller)”]; Stiner v. Amazon.com, Inc.
    (Ohio 2020) 2020-Ohio-4632 [Ohio Products Liability Act]; Fox v.
    Amazon.com, Inc. (6th Cir. 2019) 
    930 F.3d 415
    , 425 [Tennessee
    Products Liability Act]; Milo & Gabby LLC v. Amazon.com, Inc.
    (Fed.Cir. 2017) 693 F.Appx 879, 890 [addressing federal
    intellectual property law]; Garber v. Amazon.com, Inc. (N.D.Ill.
    2019) 
    380 F. Supp. 3d 766
    , 779 [Illinois law on products liability];
    State Farm Fire and Cas. Co. v. Amazon.com, Inc. (W.D.Wis.
    2019) 
    390 F. Supp. 3d 964
    [Wisconsin products liability statute].)
    We need not stray so far afield when California courts have
    provided extensive analysis of strict liability doctrine in
    California.
    We have identified the acts constituting Amazon’s
    participation in the distribution chain. “Whatever term we use to
    describe Amazon’s role, be it ‘retailer,’ ‘distributor,’ or merely
    ‘facilitator,’ it was pivotal in bringing the product here to the
    consumer.” 
    (Bolger, supra
    , 53 Cal.App.5th at p. 438.) These acts
    support our conclusion that Amazon is in the vertical chain of
    distribution of the alleged defective hoverboard. Next, we assess
    whether applying strict liability to Amazon’s third-party seller
    23
    business model supports the relevant public policy
    considerations.
    5. Policy Considerations Underlying the Doctrine
    Are Furthered by Imposing Strict Products Liability
    in This Case
    In analyzing whether strict liability is appropriate in new
    circumstances, courts assess whether relevant public policy goals
    are furthered by its application. (Bay 
    Summit, supra
    , 51
    Cal.App.4th at p. 774.) As noted earlier in this opinion, the
    relevant public policy considerations are: (1) whether Amazon
    may play a substantial part in insuring that the product is safe or
    may be in a position to exert pressure on the manufacturer to
    that end, (2) whether Amazon may be the only member in the
    distribution chain reasonably available to the injured plaintiff,
    and (3) whether Amazon is in a position to adjust the costs of
    compensating the injured plaintiff amongst various members in
    the distribution chain. 
    (Vandermark, supra
    , 61 Cal.2d at pp. 262-
    263.) We address each in turn.
    As to product safety, Amazon contends it has no proactive
    authority over product design or manufacture because its
    relationship is typically with the distributor or retailer, not the
    manufacturer. It asserts it can only reactively address safety
    issues by removing or suspending sellers after a product has been
    shown to be unsafe. Thus, imposing strict liability on it will not
    enhance product safety.
    By its very argument, Amazon acknowledges it plays a role
    in ensuring product safety. Indeed, sellers are required under
    the BSA to comply with all applicable laws, including,
    presumably, consumer safety laws and regulations. The evidence
    shows Amazon may require proof that a product complies with
    24
    recognized safety standards before it is listed. For example,
    Amazon may require documentation or certification from the
    Underwriter’s Laboratories, which sets forth standards for
    manufacturing practices and devises safety tests for products.
    Additionally, Amazon on occasion has consulted with the CPSC
    to determine if there are specific regulations or issues related to
    products it lists that are “outside of the norm.”
    These steps, which Amazon has taken to ensure product
    safety in limited circumstances, refute its contention it has no
    ability to proactively affect product safety. Application of strict
    liability in this case may incentivize Amazon to expand its safety
    compliance requirements to more products and thus further the
    goal of product safety.
    Moreover, we agree with Bolger that “[j]ust like a
    conventional retailer, Amazon can use its power as a gatekeeper
    between an upstream supplier and the consumer to exert
    pressure on those upstream suppliers (here, third party sellers)
    to enhance safety.” 
    (Bolger, supra
    , 53 Cal.App.5th at p. 454.)
    Under the BSA, “Amazon sets fees that it would retain for the
    sale of a third-party product, protects itself by requiring third-
    party vendors to indemnify Amazon should any ‘claim, loss,
    damage, settlement, cost, expense or other liability’ occur, and
    reserves the right to refuse to provide . . . services for a product
    that does not comport with Amazon’s policies. With the rights
    retained, Amazon could halt the placement of defective products
    in the stream of commerce, deterring future injuries.” (Gartner v.
    Amazon.com, Inc. (S.D.Tex. 2020) 
    433 F. Supp. 3d 1034
    , 1044,
    citation omitted.)
    As to consumer compensation, Amazon may be the only
    member of the distribution chain reasonably available for an
    25
    injured consumer to recover damages. Amazon contends there is
    no evidence to show how frequently an injured plaintiff is truly
    left without recourse. The record shows, however, that Forrinx,
    the only other defendant in this matter, failed to appear and a
    default was taken against it. Indeed, the same issue arose in
    Bolger, where two defendants failed to appear, and a third could
    only be served in China. 
    (Bolger, supra
    , 53 Cal.App.5th at p. 453;
    see also Fox v. Amazon.com, 
    Inc., supra
    , 930 F.3d at p. 424.)
    As to loss spreading, Amazon can adjust the costs of
    consumer protection between it and third party sellers through
    its fees, indemnity requirements, and insurance. Amazon does
    not argue it is unable to spread the costs in these, and other,
    ways. It instead contends these costs will result in higher prices
    to be paid by consumers and small businesses will also be
    required to bear these higher costs. Amazon’s argument
    obfuscates the goal of loss spreading. At issue is whether the loss
    should be borne solely by the injured consumer who may have no
    recourse against other defendants, or whether it may be spread
    among those who profited from the sale of the defective product.
    In our view, these policy considerations support the application of
    strict liability to Amazon’s third party seller business model.
    Lastly, Amazon contends the policies articulated by the
    California Supreme Court in Greenman and Vandermark are
    incomplete and have been eroded by subsequent events. Indeed,
    Amazon questions whether strict liability has brought benefits
    commensurate with its substantial costs. These are issues best
    directed to the California Supreme Court, who created strict
    products liability doctrine almost 60 years ago and whose
    decisions we are bound to follow. (Auto Equity Sales, Inc. v.
    Superior Court (1962) 
    57 Cal. 2d 450
    , 455.)
    26
    Accordingly, we hold the application of strict liability to
    Amazon’s third-party seller business model is supported by the
    relevant public policy consideration discussed in Vandermark.
    III. Summary Adjudication Was Improperly Granted as
    to the Negligent Products Liability Claim
    Loomis also challenges the summary adjudication of her
    negligence claim, contending Amazon failed to meet its burden to
    demonstrate that one or more elements of the claim cannot be
    established or that there is a complete defense to the claim.
    Amazon argues it does not owe Loomis a duty of care for the
    same reason it is not strictly liable: it did not manufacture or sell
    the product. It asserts “[a]n element of a product-liability claim
    is that the defendant manufactured or sold the product. Her
    failure to establish that element doomed her . . . strict-liability
    and negligence claims.” Amazon’s position is reasonable given
    that “[t]he theories of negligence and strict liability ‘parallel and
    supplement each other’ [citation], and the same policy
    considerations that militate for or against imposition of strict
    liability may apply with equal force in the context of negligence.
    [Citations.]” (Bettencourt v. Hennessy Industries, Inc. (2012) 
    205 Cal. App. 4th 1103
    , 1118.) However, Amazon provides no legal
    support for its argument that negligent products liability may
    only be imposed on manufacturers and sellers.
    Instead, a duty of care may be imposed on a defendant who
    is not a manufacturer or seller in the context of a negligent
    products liability claim if certain policy factors are met. The
    O’Neil court explained, “Courts of this state have traditionally
    considered several factors in determining the existence and scope
    of duty: ‘the foreseeability of harm to the plaintiff, the degree of
    certainty that the plaintiff suffered injury, the closeness of the
    27
    connection between the defendant’s conduct and the injury
    suffered, the moral blame attached to the defendant’s conduct,
    the policy of preventing future harm, the extent of the burden to
    the defendant and consequences to the community of imposing a
    duty to exercise care with resulting liability for breach, and the
    availability, cost, and prevalence of insurance for the risk
    involved.’ ” 
    (O’Neil, supra
    , 53 Cal.4th at p. 364.)
    Aside from those factors which parallel strict liability
    doctrine, Amazon provided no analysis as to how it did not owe a
    duty of care to Loomis under those factors. For this reason, the
    trial court erred in granting summary adjudication as to the
    negligent products liability count.5
    5     Our conclusion that Amazon has failed to meet its burden
    on summary adjudication is not the equivalent of a finding that
    Amazon owed Loomis a duty of care or was negligent under these
    circumstances.
    28
    DISPOSITION
    The judgment is reversed. The trial court is directed to
    vacate its order granting summary judgment. A new order shall
    be entered (1) denying summary adjudication of Loomis’s strict
    products liability and negligent products liability claims as well
    as her claim for exemplary damages, and (2) granting summary
    adjudication of the remaining claims. Upon entry of the new
    order, the trial court shall conduct further proceedings not
    inconsistent with this opinion. Loomis shall recover her costs on
    appeal.

    Whatever it is, Amazon is situated swiftly to learn of and to
    contain the emerging problem, thereby reducing accidental
    injuries. Amazon can cabin the danger by stopping sales.
    Amazon can alert past buyers who have yet to experience the
    lurking hazard: Amazon has information about its customers
    and their purchases. Other measures are possible.
    Once Amazon is convinced it will be holding the bag on
    these accidents, this motivation will prompt it to engineer
    effective ways to minimize these accident costs. Tort law will
    inspire Amazon to align its ingenuity with efficient customer
    safety. Customers will benefit.
    Amazon maintains it already safeguards customer safety.
    (E.g., 
    Bolger, supra
    , 53 Cal.App.5th at pp. 442–443.) On appeal,
    Amazon’s brief says it “voluntarily implemented a product safety
    system years ago, independent of the specter of tort liability, and
    . . . it spends hundreds of millions of dollars annually to ensure
    that products offered on the website are safe, compliant, and
    authentic.” The cited source of this assertion is not the record,
    but rather an online press release “written by Amazon” posted in
    “response to a Wall Street Journal story about the safety of
    1
    products offered in [the Amazon.com] store.” (Amazon, Product
    safety and compliance in our store (Aug. 23, 2019),
     [as of Apr. 5, 2021], archived
    at  (AboutAmazon.com).)
    Amazon’s cited post makes the following admissions:
    “[W]e [at Amazon.com] have developed, and continuously
    refine and improve, our tools that prevent suspicious, unsafe, or
    non-compliant products from being listed in our store. [¶] Our
    proactive measures begin when a seller attempts to open an
    account. Our new seller account vetting includes a number of
    verifications and uses proprietary machine learning technology
    that stops bad actors before they can register or list a single
    product in our store. All products offered in our stores must
    comply with applicable laws and regulations, and our own
    policies. For example, we require toys to be tested to relevant
    safety standards set by the Consumer Product Safety
    Commission. We have a dedicated global team of compliance
    specialists that review submitted safety documentation, and we
    have additional qualification requirements that sellers must
    meet to offer products. In 2018, our teams and technologies
    proactively blocked more than three billion suspect listings for
    various forms of abuse, including non-compliance, before they
    were published to our store. [¶] Once a product is available in
    our store, we continuously scan our product listings and updates
    to find products that might present a concern. Every few
    minutes, our tools review the hundreds of millions of products,
    scan the more than five billion attempted daily changes to
    product detail pages, and analyze the tens of millions of customer
    reviews that are submitted weekly for signs of a concern and
    2
    investigate accordingly. Our tools use natural language
    processing and machine learning, which means new information
    is fed into our tools daily so they can learn and constantly get
    better at proactively blocking suspicious products. [¶] In
    addition, we provide a number of ways for regulatory agencies,
    industry organizations, brands, customers, and our customer
    service teams to report safety issues. When we receive these
    reports, we move quickly to protect customers, remove unsafe
    products from our store, and investigate. For example, if a
    customer reports a concern with a product, a customer service
    associate can instantly trigger an investigation. Additionally,
    because of our direct relationships with customers, we are able to
    trace and directly notify customers who purchased a particular
    product online and alert them to a potential safety issue—our
    systems are far more effective than other online and offline
    retailers and customers can feel confident they’ll have the
    information they need. [¶] We also regularly work with agencies
    including the Food and Drug Administration and Consumer
    Product Safety Commission, and the information we share helps
    them identify trends and develop regulations. We are active in
    industry working groups and committees that are dedicated to
    developing new solutions and guidelines that will benefit all
    retailers and consumers. [¶] We invest significant resources to
    protect our customers and have built robust programs designed
    to ensure products offered for sale in our store are safe and
    compliant. We want customers to shop with confidence and if
    ever a customer has a concern, they can contact our customer
    service team, and we will investigate.” 
    (AboutAmazon.com, supra
    .)

    These words are good. The admissions confirm the obvious:
    Amazon can control its river. It can undertake cost-effective
    steps to minimize accidents from defective products sold on its
    website. Strict tort liability will underline the priority Amazon
    places on its safety efforts.
    Thus we have an easy case that beautifully illustrates the
    deep structure of modern tort law: a judicial quest to minimize
    the social costs of accidents—that is, the sum of the cost of
    accidents and the cost of avoiding accidents. Judges have been
    applying this social cost-benefit analysis as a felt instinct for a
    long time, as we shortly will survey. That deep structure makes
    this case simple to decide. When efforts to minimize accident
    costs are relatively inexpensive and apt to be effective, courts
    impose tort duties. Amazon has cost-effective options for
    minimizing accident costs. Amazon therefore has a duty in strict
    liability to the buyers from its site, including Kisha Loomis.
    I
    In large measure, tort law is cost-benefit analysis.
    Comparing the cost to the benefit of an activity is rational
    thinking. All else equal, it is rational to invest in ventures where
    the expected return exceeds the cost. Conversely, it is irrational
    to spend $2 of your own money to get something you value only at
    $1.
    The judicial use of cost-benefit analysis is familiar
    throughout tort doctrine, in the doctrines of negligence as well as
    strict liability. In contrast to formal cost-benefit analyses in
    other spheres, this judicial practice does not compare quantified
    sums of dollar and cents on a balance sheet; case records nearly
    never contain precise data of the right kind. Rather, the
    4
    litigation setting forces judicial reasoning to be more seat-of-the-
    pants, more commonsensical than that.
    We see this commonsensical method over and over through
    the decades.
    The intellectual history of cost-benefit analysis in tort law
    goes back at least a century. (E.g., Berkovitz v. American River
    Gravel Co. (1923) 
    191 Cal. 195
    , 199 (Berkovitz); see also Chicago,
    Burlington & Quincy Railroad Co. v. Krayenbuhl (Neb. 1902) 
    65 Neb. 889
    , 902–904 [
    91 N.W. 880
    , 882–883].)
    Shortly we return to the 1923 Berkovitz decision.
    In 1944, Justice Roger Traynor—California’s most
    esteemed jurist—explained tort doctrine must aim to minimize
    the social costs of accidents. (Escola v. Coca Cola Bottling Co.
    (1944) 
    24 Cal. 2d 453
    , 462 (conc. opn. of Traynor, J.) [“public
    policy demands that responsibility be fixed wherever it will most
    effectively reduce the hazards to life and health inherent in
    defective products”] (Escola); see also Greenman v. Yuba Power
    Products, Inc. (1963) 
    59 Cal. 2d 57
    , 63–64 (Traynor, J.)
    [unanimous court adopts logic of Traynor’s concurring Escola
    opinion] (Greenman).)
    Justice Traynor’s Greenman decision had enormous impact.
    “Within a decade of Greenman, a majority of jurisdictions in the
    United States had adopted causes of action in strict product
    liability. Today all but a handful of states employ some version of
    products liability law.” (Goldberg et al., Tort Law:
    Responsibilities and Redress (3d ed. 2012) p. 887.)
    Shortly after Escola, Judge Learned Hand formalized tort
    law’s efficiency calculus with enduring precision. (United States
    v. Carroll Towing Co. (2d. Cir. 1947) 
    159 F.2d 169
    , 173
    [defendant’s duty is a function of three variables: (1) the
    5
    probability of an accident; (2) the gravity of the injury from an
    accident; versus (3) the burden—that is, the cost—of adequate
    precautions]; see Posner, A Theory of Negligence (1972) 1 J. Legal
    Stud. 29, 32–33.)
    In 1970, Professor (and now Senior United States Circuit
    Judge) Guido Calabresi treated tort law’s deep structure in his
    landmark book, The Costs of Accidents (Calabresi). In
    Calabresi’s approach, courts can use cost-benefit analysis to
    appraise whether defendants can make cost-effective accident
    avoidance investments. Where the benefit of investments in
    accident avoidance outweighs the cost, courts should impose tort
    duties on defendants. But courts refrain from imposing tort
    duties in situations where the options for accident avoidance are
    so limited that the costs of accident avoidance do not outweigh
    the benefits. (Cf. Posner, Guido Calabresi’s The Costs of
    Accidents: A Reassessment (2005) 64 Md. L.Rev. 12, 15
    [Calabresi’s framework approximated cost-benefit analysis].)
    In 1978, the California Supreme Court’s Barker decision
    explicitly put cost-benefit analysis into the heart of tort law.
    (Barker v. Lull Engineering Co. (1978) 
    20 Cal. 3d 413
    .) The
    question was whether a vehicle called a high-lift loader was a
    defective product. Lumber tipped off a loader working on a hilly
    construction site. The falling lumber injured the driver, who
    sued the manufacturer, saying the loader was a defective
    product: the manufacturer could have made the loader with
    stabilizing mechanical arms, which the driver maintained would
    have prevented the tipping and his injury. The manufacturer
    disagreed, saying its loader design was not defective at all; rather
    the problem was the bad decision to use the loader on a steep hill,
    where of course things would tip over. To resolve the issue, our
    6
    Supreme Court crafted a cost-benefit standard: do the benefits of
    the challenged design outweigh the risk of danger inherent in
    such design? (Id. at pp. 418–421 & fn. 2, 426–427, 430–435.)
    Thus, a product is defective if its design embodies excessive
    preventable danger: that is, unless the benefits of the design
    outweigh the risk of danger inherent in such design. (Soule v.
    General Motors Corp. (1994) 
    8 Cal. 4th 548
    , 567, 570.) The Barker
    decision also formulated the alternative “consumer expectations”
    test. (Barker, at pp. 429–430.)
    By the 1980s, the notion of tort cost-benefit analysis was
    mainstream. (See Evra Corp. v. Swiss Bank (7th Cir. 1982) 
    673 F.2d 951
    , 958 (Posner, J.) [“The amount of care that a person
    ought to take is a function of the probability and magnitude of
    the harm that may occur if he does not take care”].)
    In 2016, the California Supreme Court cited Calabresi’s
    enduring cost-benefit approach in its unanimous Kesner opinion.
    (Kesner v. Superior Court (2016) 
    1 Cal. 5th 1132
    , 1153, citing
    
    Calabresi, supra
    [courts should assign tort liability to ensure
    those best situated to prevent injuries are incentivized to do so]
    (Kesner).)
    We return to Kesner shortly.
    This developing tort doctrine brings us to today and to
    Amazon.
    Under this doctrine, Amazon owes its customers a duty in
    strict liability because Amazon’s position in the distribution chain
    allows it to take cost-effective steps to reduce accidents. The cost-
    benefit analysis in Amazon’s case is not a close call: the benefits
    of the actions Amazon can take to minimize accidents vastly
    outweigh the costs of these actions to Amazon. Amazon’s options
    are practical and cost-effective; indeed, Amazon says it is already
    7
    taking these actions. Amazon thus must face strict liability for
    Loomis’s fiery encounter with the hoverboard she bought from
    Amazon’s site. Imposing this duty on Amazon creates financial
    incentives that back up Amazon’s good words about its concern
    for customer safety.
    Some suggest considerations of moral justice can compete
    with tort law’s calculus of social benefit. (E.g., Simons, Tort
    Negligence, Cost-Benefit Analysis, and Tradeoffs: A Closer Look
    at the Controversy (2008) 41 Loyola L.A. L.Rev. 1171, 1172–1173;
    Schwartz, Mixed Theories of Tort Law: Affirming Both
    Deterrence and Corrective Justice (1997) 75 Tex. L.Rev. 1801,
    1819–1820.) This case presents no potential conflict like that.
    The only time Amazon’s brief uses the word “justice” is to write
    “the Bolger Court saw the ‘novelty of these issues’ as an opening
    to use law as ‘an instrument of justice’ to implement ‘current
    concepts of what is right and 
    just.’ 53 Cal. App. 5th at 462
    (quoting Kriegler v. Eichler Homes, Inc., 
    269 Cal. App. 2d 224
    ,
    227 (1969)).” If they ever do, moral justice and cost-benefit
    analyses do not conflict in this case.
    II
    The case law jibes completely with this cost-benefit
    analysis. This is true for decisions that impose tort duties, as
    well as for decisions that refuse to impose tort duties. We see this
    consistency in both categories of decisions. We begin with
    decisions that impose duties.
    A
    Courts impose tort duties on entities situated to take cost-
    effective measures to reduce the costs of accidents. Six
    precedents illustrate this point.
    8
    1
    Justice Traynor’s Escola opinion proposed making Coca
    Cola strictly liable for an exploding cola bottle. The company was
    positioned to fix the problem through efficient accident avoidance
    measures. Coca Cola could have pressurized bottles more
    carefully, bought stronger bottles, tested more thoroughly,
    switched to cans, or used any combination of tactics. (See 
    Escola, supra
    , 24 Cal.2d at p. 459 [“The bottle was admittedly charged
    with gas under pressure, and the charging of the bottle was
    within the exclusive control of [Coca Cola]”];
    id. at p. 461
    [Coca
    Cola “had exclusive control over both the charging and inspection
    of the bottles”];
    id. at p. 462
    (conc. opn. of Traynor, J.) [the bottler
    “is best situated to afford such protection” from the problem of
    exploding soda bottles].) Coca Cola made the key decisions and
    so was positioned to make soda containers safer—or, if cost-
    effective fixes were impossible, to stop marketing the product
    altogether. Justice Traynor thus urged strict liability to force the
    company to internalize the accident costs it had been imposing on
    its customers. The Supreme Court unanimously affirmed the
    judgment against Coca Cola. (Id. at p. 461.)
    2
    In the same way, the Greenman decision imposed strict
    liability on a lathe maker that could have used better set screws
    to hold spinning wood more securely. Improved screws could
    have made the wood less likely to fly off the lathe and hurt the
    operator. (See 
    Greenman, supra
    , 59 Cal.2d at p. 60.) Again, tort
    law forced the manufacturer to internalize the costs of accidents
    from its product.
    9
    3
    The Vandermark opinion extended strict liability to a car
    retailer that sold a new Ford to one Chester Vandermark.
    (Vandermark v. Ford Motor Co. (1964) 
    61 Cal. 2d 256
    .)
    Vandermark claimed the car’s braking defect caused it to crash.
    For the unanimous court, Justice Traynor applied strict liability
    to the retailer as well as to the manufacturer, because the
    retailer was positioned to take actions to reduce the costs of
    accidents from defective products. The retailer was part of the
    manufacturer’s overall marketing enterprise and in some cases
    would be the only member of that enterprise reasonably available
    to injured plaintiffs. The retailer’s continuing business
    relationship with the manufacturer would allow dealers to exert
    pressure on the possibly remote manufacturer as an added safety
    incentive. (See
    id. at pp. 261–263.)
    The dealer never suggested
    its ability to exert pressure on Ford was so costly and ineffective
    as to be impractical.
    4
    Rowland v. Christian (1968) 
    69 Cal. 2d 108
    is another
    important case imposing tort liability on a decision maker
    positioned to undertake efficient accident precautions. The
    opinion put a duty on Nancy Christian, who knew the bathroom
    faucet handle in her apartment was cracked and needed
    replacing. Christian invited James Rowland to the apartment.
    Rowland said he was going to the bathroom. The handle broke
    and cut Rowland when he tried to use it. The court held
    Christian owed a duty to warn Rowland of the faucet crack. (Id.
    at pp. 110–112.)
    This ruling made perfect cost-benefit sense. It would have
    cost Christian little to share her knowledge of the latent danger
    10
    with Rowland. The information would have allowed Rowland to
    take suitable care. Imposing this accident avoidance duty on the
    knowledgeable property possessor was efficient and thus socially
    rational. The fact this was a negligence case shows cost-benefit
    analysis in tort law is not confined to the context of strict
    liability.
    5
    The previously mentioned Kesner case illustrated the logic
    of tort law’s cost-benefit analysis, and again outside the strict
    liability setting. Employees unwittingly carried workplace
    asbestos dust home to family members, who breathed it in and
    developed mesothelioma from the take-home exposure. The
    unanimous Supreme Court ruled the employers had a duty to the
    family members. 
    (Kesner, supra
    , 1 Cal.5th at pp. 1141, 1156,
    1165.)
    The tort goal was “incentivizing reasonable preventative
    measures.” 
    (Kesner, supra
    , 1 Cal.5th at p. 1151.) The employers
    did “not claim that precautions to prevent transmission via
    employees to off-site individuals—such as changing rooms,
    showers, separate lockers, and on-site laundry—would
    unreasonably interfere with business operations.” (Id. at p.
    1153.) Employers “are generally better positioned than their
    employees or members of their employees’ households to know of
    the dangers of asbestos and its transmission pathways, and to
    take reasonable precautions to avoid injuries that may result
    from on-site and take-home exposure.” (Ibid.; see also
    id. at p. 1156
    [“Businesses making use of asbestos were well positioned,
    relative to their workers, to undertake preventive measures, and
    [the employers] cite no evidence to suggest such measures would
    have been unreasonably costly.”].)
    11
    The cost-benefit analysis thus was simple: the employers
    had cost-effective accident avoidance measures available to them,
    so they owed a duty in tort to family members facing take-home
    asbestos exposure. (See 
    Kesner, supra
    , 1 Cal.5th at pp. 1154–
    1156.)
    6
    Amazon repeatedly cites a Court of Appeal decision: Bay
    Summit Community Assn. v. Shell Oil Co. (1996) 
    51 Cal. App. 4th 762
    (Bay Summit), which concerned Shell Oil’s liability for leaky
    polybutylene plumbing systems. This decision is instructive, as
    is the whole polybutylene saga. Both cut against Amazon.
    Polybutylene was a plastic used for water piping.
    “Beginning in the late 1970s, polybutylene plastic plumbing
    systems—touted as being cheaper and more durable than copper
    pipe systems—were installed in new homes nationwide . . . .
    Over the years, several million homes, many of them mobile
    homes, were built with polybutylene plumbing systems. Before
    long, the plumbing systems began to experience failures of the
    fittings and of the pipe itself.” (Hensler et al., Class Action
    Dilemmas: Pursuing Public Goals for Private Gain (2000) p. 375,
    fn. omitted (RAND).)
    Polybutylene piping was the classic defective product. It
    seemed like a good thing when introduced, but over time it
    literally failed to hold water. Chlorine in drinking water
    apparently caused it eventually to crack and leak, leading to
    nationwide litigation and massive settlements involving some
    220,000 replumbing jobs and many millions of dollars. 
    (RAND, supra
    , at p. 390.)
    In 1977, Shell Oil Company had begun manufacturing
    polybutylene resin—the raw material for the pipes—and it was
    12
    the sole manufacturer of polybutylene resin. But Shell entirely
    withdrew the product from the U.S. market in 1996. 
    (RAND, supra
    , at p. 375.)
    The Bay Summit decision was one chapter in the
    nationwide litigation that drove Shell out of the polybutylene
    market. In Bay Summit, the case’s record was very limited and
    in conflict as to (1) whether Shell did in fact control the
    manufacturing or distribution process and (2) whether it was an
    integral factor in bringing a polybutylene plumbing system to
    market. (Bay 
    Summit, supra
    , 51 Cal.App.4th at p. 778.) The
    court remanded the case for a factual determination of whether
    Shell “had control over, or a substantial ability to influence, the
    manufacturing or distribution process.” (Ibid.) Absent this
    ability to control or influence the manufacturing or distribution
    system, Shell could not be strictly liable for leaking polybutylene
    plumbing systems.
    Bay Summit is a disastrous precedent for Amazon because,
    unlike in Bay Summit, there is no doubt about Amazon’s ability
    to control the distribution system Amazon invented. Amazon is
    the distribution system. It thus should be strictly liable for
    defective products people buy from its site.
    Beyond the particular Bay Summit decision, the entire
    polybutylene saga is an example of how tort law can lead to
    socially rational decisionmaking by forcing commercial actors to
    internalize the costs of their actions. According to the RAND
    analysis, the final outcome was that polybutylene piping
    disappeared from the U.S. marketplace because it was faulty.
    Apparently it was cheaper to switch to different kinds of plastic
    than to bear the tort liability for polybutylene. If the product is
    13
    defective, the sooner it is fixed or disappears, the better. This
    saga favors Loomis, not Amazon.
    These six cases show courts have used cost-benefit analysis
    to decide whether to impose tort duties. Six cases on the other
    side of the coin show the same method.
    B
    Courts refrain from imposing tort duties where measures to
    avoid accidents are burdensome and unlikely to be cost-effective.
    This notion initially may seem off-putting: do we not seek to
    avoid accidents at all costs? No, we do not. As Calabresi
    explained, “[w]e take planes and cars rather than safer, slower
    means of travel.” (
    Calabresi, supra
    , at p. 18.) At some point, a
    quest for perfect safety becomes irrationally expensive. Six cases
    show how judicial cost-benefit analysis can locate this point.
    1
    The previously cited Berkovitz decision illustrates this
    judicial instinct. It used the cost-benefit method long before that
    terminology appeared in tort decisions.
    The Berkovitz accident was in 1919. Two couples in a
    “Dodge touring car” were breaking the speed limit at 2:00 a.m. in
    a city and rear-ended a gravel truck going about 10 miles per
    hour. 
    (Berkovitz, supra
    , 191 Cal. at pp. 197–198.) People in the
    Dodge sued the truck company, claiming the truck’s coal-oil tail
    lamp was out. If true, that would have violated the law requiring
    a night light and thus would have been negligence per se. The
    evidence conflicted about the coal-oil lamp. The truck driver said
    he saw the reflection of the tail light three or four blocks before
    the accident scene and it was working then, so by his account the
    light must have failed in those three or four blocks—just
    moments before the crash. (Id. at p. 198.) The Supreme Court
    14
    ruled that, under these circumstances, the truck company was
    entitled to an excuse instruction. (Id. at pp. 199–200.) The
    Berkovitz court permitted the excuse defense because it, in
    essence, decided the conduct the trucker described was efficient.
    The trucker claimed he made sure his light was working just
    before the accident. There was no other better and yet practical
    way for the trucker to check his tail light: in 1919, dashboard
    alerts about failed tail lights were things of the future. In that
    year, the only way the trucker could have been more cautious
    would have been to post a person “over the rear light to observe
    whether it is constantly burning.” (Id. at p. 199.) This lookout
    notion was obviously preposterous in the court’s view. This
    extreme measure would have been socially uneconomical—like
    forcing all interstate traffic today to drive at 10 miles per hour to
    minimize accidents. That much safety would be socially
    irrational.
    Because the precaution cost would have been high while
    the accident risk from a very-briefly-unlit tail light was low, the
    Berkovitz decision refused to impose an absolute per se duty on
    the trucker. The cost of the additional precaution was socially
    irrational: posting lookouts on the back of every motor vehicle
    would have been more costly than the safety benefit would
    justify.
    2
    A second example is O’Neil v. Crane Co. (2012) 
    53 Cal. 4th 335
    (O’Neil). Amazon relies on O’Neil, but that decision
    contradicts Amazon’s argument.
    The key feature about the O’Neil case was that defendant
    Crane made valves but was being sued for replacement asbestos
    gaskets Crane did not make. When workers refurbish an old
    15
    leaky valve, they predictably put new replacement gaskets in the
    valve. But the O’Neil decision held valve maker Crane owed no
    tort duty, either in negligence or strict liability, to people
    repairing its valves who breathed dust from the replacement
    asbestos gaskets Crane did not make. 
    (O’Neil, supra
    , 53 Cal.4th
    at p. 342.)
    Crane could foresee workers repairing its valves would use
    asbestos gaskets made by other companies. 
    (O’Neil, supra
    , 53
    Cal.4th at p. 342.) So why did Crane have no tort duty? Because
    the Supreme Court said the cost of imposing this duty on one
    firm to warn of dangers from products from other manufacturers
    would outweigh the benefit of resulting injury reductions. This
    duty would be tremendously and ineffectively overbroad: like
    requiring “match manufacturers to warn about the dangers of
    igniting dynamite.” (Id. at p. 361.) But when every firm must
    warn everybody about everything, the costly exercise does no
    good. “ ‘To warn of all potential dangers would warn of nothing.’ ”
    (Id. at p. 363, quoting Andre v. Union Tank Car Co., Inc. (1985)
    
    213 N.J. Super. 51
    , 67 [
    516 A.2d 277
    , 286].)
    O’Neil’s cost-benefit analysis meant the court refused to
    impose a tort duty where it would be socially irrational to do so.
    Crane did not control the marketing of gaskets made by other
    firms. Amazon, by contrast, completely controls its river. There
    is nothing socially irrational or ineffectively redundant about
    making Amazon strictly liable for accidents from products bought
    from its website.

    The same principle governed Peterson v. Superior Court
    (1995) 
    10 Cal. 4th 1185
    , 1188–1189 (Peterson), which ruled land
    and hotel owners are not strictly liable for injuries to their
    16
    tenants and guests caused by an unknown defect in the premises.
    The owners remained liable in negligence; injured guests
    retained a strict liability action against the manufacturer,
    distributors, and retailers of the allegedly defective products.
    But to extend the strict liability duty to land owners for unknown
    defects owners did not create and could not discover through a
    reasonable inspection would mean imposing costly duties without
    a compensating benefit in accident reduction. “A landlord or
    hotel owner, unlike a retailer, often cannot exert pressure upon
    the manufacturer to make the product safe and cannot share
    with the manufacturer the costs of insuring the safety of the
    tenant, because a landlord or hotel owner generally has no
    ‘continuing business relationship’ with the manufacturer of the
    defective product. . . . ‘The cost of insuring risk will not be
    distributed along the chain of commerce but will probably be
    absorbed by tenants who will pay increased rents.’ ” (Id. at p.
    1199.) “Because of the practical impossibility of obtaining expert
    knowledge of all the components of an apartment, landlords must
    rely on others for their safe manufacture, installation and repair.
    In this respect, landlords are in no better position to know of
    defects than are tenants.” (Id. at p. 1209.)
    By contrast, Amazon is in a better position than its
    customers to learn of and to combat defects in products on its
    website.

    Parsons v. Crown Disposal Co. (1997) 
    15 Cal. 4th 456
    (Parsons) is conceptually similar to O’Neil and Peterson. Darrell
    Parsons was riding his horse on an urban bridle path when a
    truck noisily lifted a nearby trash bin. The crashing sound made
    the horse bolt, throwing Parsons to the ground. (Id. at p. 462.)
    17
    Parsons sued the trash company. The Supreme Court ruled the
    company owed Parsons no tort duty. The Supreme Court used a
    “social utility analysis” to evaluate accident avoidance measures
    the trash company could have taken: “changing the hours of
    collection, temporarily ‘blocking off’ the area with warning cones
    or tape, posting warning signs, providing riders with a schedule
    of collection times, or a combination of these methods.” (Id. at p.
    474.) The court rejected Parsons’s proposals because they would
    increase “the burden on machine operators over what was
    considered reasonable.” (Ibid.) These precautions “unreasonably
    would impair the utility” of the trash company, which ran a
    business “of high social utility.” (Ibid.) And imposing these
    duties on the trash company would imply similar restrictions on
    a wide “range of socially useful activities that may produce such
    noises and provoke such fright.” (Id. at pp. 474–475.)
    The Supreme Court illustrated its cost-benefit analysis
    with commonsense examples:
    “Should a homeowner whose property abuts this extensive
    bridle path (or who has horse-owning neighbors) be obligated to
    peek over his or her six-foot fence to make sure that no horse is
    near before starting a power lawn mower? Should he or she be
    required somehow to keep a constant lookout while mowing the
    lawn, lest he or she frighten a horse that approaches shortly after
    lawn mowing begins? Should a homeowner or building contractor
    be obligated to undertake similar procedures before and during
    use of chain saws, leaf blowers, or other loud power tools? What
    about noise from passing cars and trucks on the adjacent
    highways, or from a picnicker’s radio, or from an emergency siren
    or alarm, or from a jetliner’s sonic boom? We conclude that
    imposing a duty in the present case to guard against fright to a
    18
    horse might well subject all manner of actors to the same duty
    and potential liability, with obvious and detrimental
    consequences stifling to the community.” 
    (Parsons, supra
    , 15
    Cal.4th at p. 475, emphasis in original.)
    In short, this seat-of-the-pants cost-benefit analysis showed
    the accident avoidance Parsons had proposed for the trash
    company was not worth its cost. These proposed safety measures
    were just as obviously inefficient as lookouts on 1919 trucks to
    see if the coal-oil lamp was still lit. (Cf. Grady, The American
    Negligence Rule (2019) 53 Val.U. L.Rev. 545, 576 [Parsons
    basically held the untaken precautions “flunked the Learned
    Hand formula”].)
    When accident avoidance will be costly and ineffective, the
    Supreme Court refuses to burden defendants with tort duties.
    Amazon loses under this rule, for it can take cost-effective actions
    to minimize the cost of accidents. Indeed, it claims it already
    does.
    The same rule explains the lower court California cases on
    which Amazon relies. These Court of Appeal decisions concern
    two situations: secondhand dealers and finance lessors. We treat
    each in turn.
    5
    The secondhand dealer cases declined to impose a duty in
    strict liability because the dealers were unable to take cost-
    effective measures to minimize accidents from the secondhand
    machines they sold.
    Wilkinson v. Hicks (1981) 
    126 Cal. App. 3d 515
    (Wilkinson)
    is representative. Robert Wilkinson injured his hand operating a
    50-year-old Niagara punch press at the Mac Smith Company.
    Benmatt Industries owned the press for many years. Then
    19
    defendant Roy Hicks, a dealer in secondhand industrial
    machinery, bought it from Benmatt and sold it “as is” to Mac
    Smith Company. Wilkinson sued Hicks, but the trial court
    disallowed the strict liability claim. Only the negligence action
    went to the jury, which ruled against plaintiff Wilkinson. (Id. at
    pp. 516–519.)
    On appeal, the court affirmed secondhand dealer Hicks
    owed no strict liability duty to Wilkinson. Imposing strict
    liability on secondhand dealers would require them “routinely to
    dismantle, inspect for latent defects, and repair or recondition
    their products.” 
    (Wilkinson, supra
    , 126 Cal.App.3d at p. 521.)
    That rule “would effect a radical change in the nature of the used
    product market, which would deprive that market of [its]
    desirable flexibility.” (Ibid.) The proposed rule would make used
    goods dealers the insurers of the goods they sold. (Ibid.) This
    would increase the prices of secondhand goods. (Id. at p. 520.)
    In a nutshell, plaintiff Wilkinson proposed requiring
    secondhand dealers to take expensive safety measures:
    dismantling, inspecting, repairing, and granting a mandatory
    warranty. The court, quite reasonably, was not convinced these
    steps were cost-effective in light of the existing strict liability
    duties on the original manufacturer and its original distribution
    network. Wilkinson’s proposed safety measures were too
    expensive and ineffective to be socially desirable. So Hicks owed
    no strict liability duty to Wilkinson. (Accord, Brejcha v. Wilson
    Machinery, Inc. (1984) 
    160 Cal. App. 3d 630
    ; Tauber–Arons
    Auctioneers Co. v. Superior Court (1980) 
    101 Cal. App. 3d 268
    .)
    In contrast, the measures Amazon can take to minimize the
    cost of accidents are cost-effective and socially efficient.

    The same principle guided the finance lessor decision in
    Arriaga v. CitiCapital Commercial Corp. (2008) 
    167 Cal. App. 4th 1527
    . Guillermo Arriaga suffered a work injury while operating
    a glue spreader machine. Black Bros. manufactured the glue
    spreader and sold it to Klors, which resold it to CitiCapital
    (actually, its predecessor, which we ignore), which leased it to
    AVP, which sold it to Orepak, which employed Arriaga. (Id. at
    pp. 1532–1533.) The injured Arriaga sued many parties,
    including CitiCapital. The court analogized CitiCapital’s role to
    that of a bank that loaned purchase money to AVP. (Id. at p.
    1536.) The court refused to put a duty of strict liability on
    CitiCapital in part because the court could not see what
    CitiCapital might do to “enhance product safety.” (Id. at p. 1537.)
    “[T]he finance lessor is not in any position to either directly or
    indirectly exert pressure on the manufacturer to enhance the
    safety of the product.” (Id. at p. 1538; see also
    ibid. [“the finance lessor
    does not have control over, or a substantial ability to
    influence, the manufacturing or distribution process”];
    id. at 1539
    [“the finance lessor’s relationship with a particular manufacturer
    does not, in the normal course, possess the continuity of
    transactions that would provide a basis for indirect influence over
    the condition and safety of the product”].)
    In short, there was no action, let alone any cost-effective
    action, the finance lessor could take to reduce the likelihood of
    glue spreader accidents. The Arriaga court thus refused to
    impose tort duties on the finance lessor. The contrast with
    Amazon’s situation is obvious.

    Amazon’s citations thus offer it no support. All involve
    defendants who, unlike Amazon, had no cost-effective way to
    reduce the costs of accidents.
    This case is easy. Amazon is well situated to take cost-
    effective measures to minimize the social costs of accidents.
    Strict liability will prompt this beneficial conduct. Loomis wins
    this appeal. The case will return to the trial court for resolution
    of issues the appeal has not addressed.
