Q: A new truck, manufactured by General Motors Corp. (GMC), stalled in rush hour tra?c on a busy interstate highway because of a defective alternator, which caused a complete failure of the truck's electrical system. The driver stood nearby and waved tra?c around his stalled truck. A panel truck approached the GMC truck. Immediately behind the panel truck, Davis was driving a Volkswagen fastback. Because of the panel truck, Davis was unable to see the stalled GMC truck. The panel truck swerved out of the way of the GMC truck, and Davis drove straight into it. The accident killed him. Davis's widow sued GMC. GMC moved for summary judgment, alleging
(1) no duty to Davis;
(2) no factual causation; and
(3) no foreseeable harm.
Comment on the three defenses that GMC has raised.
