The Self-Driving Collision

Model answer

**1. DALE WAS NEGLIGENT** Every driver owes a duty of reasonable care to others on the road. Dale breached that duty by securing a seven-foot metal extension ladder to the side of a flatbed with bungee cords at highway speeds. But-for causation is met: had the ladder been properly secured, the Lumen would not have struck it. Proximate causation is met because the foreseeable risk of inadequately secured highway cargo is exactly the kind of collision that occurred. Worth FLAGGING for investigation: a commercial truck hauling construction equipment on an interstate may be subject to cargo-securement statutes or regulations, which could support negligence per se or evidence of negligence. These facts do not identify the governing rule, so do not declare a violation - ordinary negligence remains the established analysis.

**2. FASTFREIGHT IS VICARIOUSLY LIABLE** Dale was hauling cargo for his employer when the ladder fell. That is squarely within the scope of his employment. Under respondeat superior, FastFreight is vicariously liable for Dale's negligence. The handbook's weak instruction to "secure cargo when practical" does not immunize the employer. Stop there rather than reaching for negligent supervision: that theory ordinarily needs evidence FastFreight knew or should have known Dale was incompetent or unsafe, and the handbook supplies none. A negligent-policy or training theory would need its own causation evidence the facts do not give.

**3. THE OBSTACLE-DETECTION SYSTEM WAS DEFECTIVE (MANUFACTURING DEFECT IS THE CLEANER THEORY)** Corvus is strictly liable for a product defect that caused foreseeable harm. Camera miscalibration impairing the integrated detection system in 2% of a specific quarter's build is a classic manufacturing-defect pattern: the product deviated from its intended design. Do NOT reach for design defect on these facts. Nothing suggests the intended DESIGN of the detection system was defective - the evidence is of factory miscalibration in a subset of vehicles, which is a failure to execute the design. A design-defect theory would require evidence that the intended design itself was defective under whatever test the jurisdiction applies (jurisdictions differ - reasonable alternative design, consumer expectations, or burden-shifting), and these facts do not supply it. The 2% incidence SUPPORTS the inference of a manufacturing deviation without being diagnostic on its own - a design, component or process problem could also affect a subset. The stronger facts are the factory miscalibration itself and the deviation from intended calibration. The factory miscalibration and its persistence in the vehicle of Harper support the inference that the defect existed when the vehicle left the control of Corvus and remained substantially unchanged thereafter - that, not merely leaving a factory, is the operative question. On CAUSATION, be consistent with section 4 rather than assuming it: the facts establish why the detection system failed to register the ladder, but plaintiffs must still show that proper camera calibration would have produced a timely response capable of preventing or mitigating this crash. One status point worth stating: Pam is a BYSTANDER rather than a user or consumer, but strict products liability extends to foreseeable bystanders under the majority rule and the Restatement (Third) of Products Liability, so under the majority and Restatement rule Pam may sue Corvus directly as a foreseeable bystander, subject to governing state law.

**4. FAILURE TO WARN; POSSIBLE INDEPENDENT DUTY TO RECALL** The internal Corvus memo is the heart of this claim (its punitive-damages significance is taken up in section 8). Eight months before the accident, an internal memo documented that the forward-CAMERA calibration was compromised in a subset of vehicles - strong support for Corvus's knowledge or notice, though the memo's author, recipients and authority are unstated. The narrative also supports an INFERENCE that Corvus understood the compromise could defeat obstacle detection, though the facts do not say the memo itself documented that consequence. The memo's RECOMMENDATION of "service-bulletin notification rather than a full recall to contain reputational risk" is the heart of the warning claim. Separate what is ESTABLISHED from what is not: no recall occurred and Harper received no notice, but the facts do not say the recommended bulletin was ever formally adopted. Be careful with the TIMELINE, though - the facts say Corvus knew eight months before the accident, but NOT whether it learned before or after THIS VEHICLE LEFT CORVUS'S CONTROL or was distributed by Corvus - and that, not Harper's purchase date, is the milestone that separates the two theories. Knowledge acquired BEFORE the vehicle left Corvus's control supports the ORIGINAL duty to warn, and depending on local law may ALSO support a continuing post-sale obligation - a later warning is not unavailable merely because the knowledge came first. Knowledge first acquired AFTER it left Corvus's control is the conventional post-sale-duty theory. Identify which the facts support before picking one, and keep RETAIL PURCHASE separate: it does not CLASSIFY the warning duty, though it may bear on notice feasibility, timing, and other local-law issues. Either way Harper received no notice. And keep FAILURE TO RECALL separate: a common-law duty to recall is much narrower than a duty to warn and is recognised only in some jurisdictions - do not merge the two. CAUSATION is the remaining element, and it is the one these claims most often fail on - breach is not enough. Pam and Harper must show an adequate warning WOULD HAVE ALTERED THE OUTCOME: that a recall or notice would have reached Harper, that she would have followed its effective instruction - obtaining recalibration, or refraining from using Assist, or whatever the warning directed - and that doing so would have avoided this collision. Many jurisdictions supply a HEEDING PRESUMPTION that a user would have followed an adequate warning - but do NOT say nothing rebuts it here. Corvus MAY ARGUE that Harper driving inattentively despite the manual's warning is rebuttal evidence - admissibility and weight depend on local law, and it is not necessarily strong, since a general attentiveness warning and a defect-specific recall notice call for materially different conduct. Do not add the chime to that argument unless evidence shows it actually sounded and she perceived it. Its weight is for the factfinder. Whether detection would actually have averted this collision is likewise a question of fact, not a given. Note also that Pam is TWO STEPS REMOVED: she must show a warning to a THIRD PARTY (Harper) would have averted her own injuries.

**5. HARPER WAS NEGLIGENT IN USING ASSIST MODE** The Assist mode requires the driver to "remain available to take control," and the manual warned it. The 90-second chime is a system FEATURE on these facts, not an established event - do not assume it sounded or that Harper perceived it. Opening a laptop and replying to work email breaches ordinary care - call it NEGLIGENT USE contrary to the warnings, not doctrinal misuse, unless local law defines misuse that broadly (distracted driving is foreseeable). Symmetry note: just as section 1 flags possible cargo-securement regulations for Dale, applicable DISTRACTED-DRIVING or electronic-device statutes may support negligence per se or evidence of negligence here - the governing jurisdiction is unidentified for both, so flag rather than decide. It matters in two places, both CONDITIONALLY. Against Pam it makes Harper a POTENTIAL concurrent cause - potential, because breach is not causation. Harper may be a causal contributor by EITHER of two routes, and the facts (ladder impact at 62 mph, then a veer into the right lane and a collision with Pam) support asking about both: (i) an ATTENTIVE driver could have avoided or mitigated the LADDER impact; or (ii) an AVAILABLE driver could have maintained or regained control AFTER that impact and avoided or mitigated the collision with Pam. Both stay conditional - the facts give no timing, steering or reconstruction evidence. Against Corvus on her OWN claim, keep the routes separate - there are two. (i) The same collision-avoidance route: could an attentive driver have avoided or mitigated the crash? (ii) An ENHANCEMENT route independent of that: placing a laptop on the steering column may have caused or aggravated her airbag injuries EVEN IF the collision was unavoidable - though that route needs medical or reconstruction evidence connecting the placement to the nature or severity of her injuries; the facts say only that the laptop was there. Either can support reduction, and WHICH comparative-fault rule applies depends on WHICH Corvus theory succeeds: a strict defect claim or a warning theory classified as strict products liability raises the special question whether this jurisdiction applies comparative responsibility to strict-products claims, whereas a NEGLIGENCE-based post-sale warning or recall theory is governed by ordinary comparative-fault rules without that prerequisite. Foreseeable negligent use does not automatically defeat a strict-products claim.

**6. APPARENTLY INDIVISIBLE HARM TO PAM - JOINT AND SEVERAL LIABILITY** The causal role of DALE is strongly supported on these facts. IF Harper and Corvus are also found liable and causally responsible, their combined conduct produced a single set of injuries from one collision - and note Corvus's exposure is STRICT PRODUCTS liability, not negligence, so do not call it all "negligence." That harm is APPARENTLY INDIVISIBLE on these facts, absent a reasonable basis for apportioning the injuries among causes. In this jurisdiction joint-and-several liability applies to indivisible injuries, so Pam may collect her full COMPENSATORY damages from any defendant FOUND LIABLE - including a party vicariously liable for a causally responsible tortfeasor (joint-and-several does not extend to punitive damages). She may obtain only ONE TOTAL SATISFACTION of her compensatory damages, not a full recovery from each. Keep the defendants straight when apportioning: FastFreight's liability here is VICARIOUS, deriving from Dale's conduct, so Dale and FastFreight should not receive DUPLICATIVE fault allocations absent proven independent negligence - and as between them the remedy is typically INDEMNITY rather than ordinary proportional contribution, though the exact verdict-form and indemnity mechanics are jurisdiction-dependent.

**7. COMPARATIVE FAULT APPORTIONMENT** Pam bears no fault, so her recovery is NOT reduced - allocation governs responsibility among liable defendants and their contribution, not her total. Apportionment is for the FACTFINDER, and these facts will not support precise numbers: there is no evidence of detection time or of Harper's opportunity to react. Name what the factfinder weighs instead - each actor's causal contribution, and, TO THE EXTENT the allocation rules of the jurisdiction permit and the theory makes them relevant, relative culpability - the duration and seriousness of the distraction by Harper, and whatever corporate knowledge, response and attributable decision-making the evidence proves (corporate culpability bears on a negligence-based warning theory or on punitives, and is not necessarily an appropriate allocation factor for STRICT manufacturing-defect liability) - plus the strength of that missing evidence - and resist inventing a split. TWO PREDICATES before Corvus is allocated anything. - LIABILITY AND CRASH CAUSATION under at least one Corvus theory, and note the theories take different causal routes. The MANUFACTURING-DEFECT theory needs proof that proper CAMERA calibration would have prevented or mitigated the crash. The FAILURE-TO-WARN theory can succeed even if it would not - for instance if an adequate warning would have led Harper not to use Assist at all - provided plaintiffs also prove that refraining from Assist would probably have prevented or mitigated the collision. Not using Assist does not by itself establish avoidance. - VERDICT-FORM TREATMENT, which is THEORY-SPECIFIC. For claims classified as STRICT products liability, it turns on whether this jurisdiction applies comparative allocation to strict-products defendants. But a POST-SALE failure-to-warn or failure-to-recall claim is often NEGLIGENCE-based, and if Corvus is liable on that footing, the special STRICT-PRODUCTS classification question may not arise - though ordinary allocation and verdict-form rules still apply. The same distinction governs the contribution mechanics. HARPER gets a share only if PAM, or another party seeking to allocate fault to her, proves causation - breach is not causal fault. Harper may be a causal contributor by EITHER of two routes, and the facts (ladder impact at 62 mph, then a veer into the right lane and a collision with Pam) support asking about both: (i) an ATTENTIVE driver could have avoided or mitigated the LADDER impact; or (ii) an AVAILABLE driver could have maintained or regained control AFTER that impact and avoided or mitigated the collision with Pam. Both stay conditional - the facts give no timing, steering or reconstruction evidence. DALE AND FASTFREIGHT should not receive DUPLICATIVE fault allocations absent independent negligence, since FastFreight's liability is vicarious - though the exact verdict-form and indemnity mechanics are jurisdiction-dependent. FINALLY, keep Harper's OWN claim separate. Any allocation made for the injuries of PAM concerns a different claim, different injuries, and an independent causal-fault determination, so it does not carry over. In the claim by Harper against Corvus her recovery is reduced by whatever percentage the factfinder independently assigns THERE - and only if the applicable rule permits reduction, which depends on the theory: the special strict-products comparative-responsibility question for a strict defect claim or a warning theory classified as strict products liability, ordinary comparative-fault rules for a NEGLIGENCE-based post-sale warning or recall theory - with the 51% bar eliminating it above 50%.

**8. PUNITIVE DAMAGES AGAINST CORVUS** START WITH THE PREDICATE: punitive damages are available only if a plaintiff first establishes an underlying Corvus claim INCLUDING CAUSATION - which sections 3 and 4 leave unproved - plus any jurisdiction-specific damages predicate. There is no standalone punitive award. On the merits, the internal memo is POTENTIALLY SIGNIFICANT evidence: it strongly supports Corvus's KNOWLEDGE OR NOTICE of the defect: it shows (i) the defect was documented internally, (ii) quantified the affected population, and (iii) considered reputational risk when recommending a service bulletin rather than a recall. It does not by itself establish CONSCIOUS DISREGARD. Treat what is missing as factual GAPS bearing on the conscious-disregard and corporate-attribution standards of the jurisdiction rather than as a fixed element list - whether Corvus understood the miscalibration created a serious SAFETY risk, whether it knowingly pursued an inadequate response, and whether any decision is attributable to the corporation. So do not characterise the memo as strong evidence of conscious disregard. If the jurisdiction permits corporate punitive damages for conscious disregard, plaintiffs must satisfy its substantive AND attribution requirements - and state the BURDEN, which answers routinely skip: most require punitive damages to be proved by CLEAR AND CONVINCING EVIDENCE rather than a preponderance. The punitive claim could satisfy that standard if ADDITIONAL evidence shows the weaker response was knowingly inadequate and the decision is attributable to Corvus under the jurisdiction's rules for corporate punitive liability. Do not treat the memo as self-proving: a service-bulletin recommendation is itself a proposed safety response, and the facts do not say whether it issued, who made the final call, or whether senior actors authorised or ratified it. Constitutional limits (BMW v. Gore, State Farm) constrain the ratio - but state them accurately. State Farm says ratios EXCEEDING single digits are suspect; it does not make every single-digit award permissible. The defensible ratio turns on reprehensibility, comparable civil or criminal penalties, and the SIZE of the compensatory award - where compensatory damages are substantial, due process may push the ratio toward 1:1.

**9. HARPER'S CLAIMS AND DAMAGES** Harper's $40,000 injuries sustained during the crash and airbag deployment support a POTENTIAL direct products claim, subject to proving defect and causation. Note the theory is the obstacle-detection defect - NO airbag defect is alleged; the airbag describes how she was hurt. IF the applicable rule permits reduction - the special strict-products question for a strict theory, ordinary comparative-fault rules for a negligence-based warning or recall theory - AND her conduct is found causally relevant to her own injuries - by the collision-avoidance route OR by the laptop having enhanced her airbag injuries even if the crash was unavoidable, which would need medical or reconstruction evidence tying its placement to the nature or severity of those injuries - then her recovery is reduced by her share and the 51% bar eliminates it above 50%. Both predicates matter - do not skip to the arithmetic. IF the call asks for potential claims BEYOND those pleaded, do not write off Dale and FastFreight. The only claim by Harper specified in the facts is against Corvus, but she appears to have a POTENTIAL claim arising from the same collision, if timely pleaded and not otherwise procedurally barred: DALE'S negligence was a but-for AND proximate cause of it, and FastFreight is vicariously liable for Dale's negligence. Neither the detection-system defect nor the inattention of Harper SUPERSEDES Dale, because a road collision is squarely within the risk created by unsecured cargo - you do not need to argue that a defective detection system was itself foreseeable to Dale. Any such recovery would be reduced - and potentially barred - ONLY if Harper's conduct is proved to have contributed causally to the collision or enhanced her injuries and the factfinder assigns her a corresponding share. Negligence by itself is not comparative fault.

**10. PAM'S DAMAGES** Pam claims $180,000 medical and $60,000 lost wages; she recovers the proven REASONABLE AND NECESSARY medical expenses and the proven collision-related lost wages, not the pleaded figures automatically. Non-economic pain-and-suffering damages are recoverable; the fractured pelvis and ongoing pain will support a substantial award. Collateral-source and insurance offsets depend on local rules.

**KEY POINT:** The call usually asks which defendants are liable and for what. The core conclusions are: (a) against Corvus, a MANUFACTURING-DEFECT claim is the cleanest theory, but liability requires proof that proper camera calibration would probably have prevented or mitigated the collision - with FAILURE TO WARN a potential additional theory that becomes strong only if the distribution timeline, the applicable ORIGINAL or POST-SALE warning-duty law (depending on when the vehicle left Corvus's control), the content of an adequate warning, heeding and avoidance causation are all established; (b) negligence + respondeat superior against Dale/FastFreight; and (c) concurrent-cause joint-and-several liability exposing each defendant FOUND LIABLE - including one vicariously liable for a causally responsible tortfeasor - to Pam's full COMPENSATORY damages, subject to one total satisfaction, and subject to any contribution and indemnity rights recognised under governing local law - ordinarily contribution among INDEPENDENTLY liable parties, and indemnity between Dale and FastFreight - with no duplicative Dale/FastFreight allocation either way. Harper is a defendant to Pam and also a plaintiff against Corvus, potentially subject to comparative-fault reduction if her conduct causally contributed to her injuries - under the special comparative-responsibility rule of the jurisdiction for a strict defect claim or a warning claim classified as strict products liability, OR under ordinary comparative-fault rules for a negligence-based post-sale warning or recall theory.
