A 63 year old bicyclist was badly injured when an 80 year old driver crashed into him on a Brooklyn street, according to officials. The driver was apparently fleeing from another accident in which he had crashed into a school bus minutes earlier and kept going, according to police. One witness “heard the screeching of the tires” and “saw the man fly over the car and land on the windshield.” This post impact motion is common to many bicycle and motorcycle collisions with cars. Once the cyclist is thrown off his bike, he may land on the car hood-windshield area or he may travel over the car and land on the ground. In either case, such accidents can produce severe injuries to the cyclist, who is likely to have little impact protection, other than a helmet.
