Amotorist driving home one night on a desolate two-lane road stopped when he saw a person lying on the road next to a bicycle. the cyclist had slipped and fell off his bicycle, and was knocked unconscious when he hit his head on the pavement. not wishing to get involved and seeing that no one else was around, the motorist got back into his car and drove away without making any effort to the cyclist, even though he had a cell phone with which he could have summoned aid. the cyclist remained lying in the same place and was later struck by another car. if the cyclist brings suit against the motorist for injuries suffered when he was struck by the other car, will the cyclist prevail? a yes, because a reasonable person under the same circumstances would have come to the cyclist's aid. b yes, because by stopping and examining the cyclist, the motorist, as a matter of law, assumed a duty to aid him. c no, because the motorist was not responsible for causing the cyclist to be lying by the side of the road. d no, because the cyclist's injuries were caused by the negligence of another driver.
