Clark was in a car wreck when he was about five years old. There were no seat belts in the back seats of cars back then, so Clark went flying and hit his head. Today, things are much different. There are air bags and side air bags and electronic stability control. There is even a requirement now that the price sticker on cars shows how safe the car is. Every car is ranked on various safety tests and the ranking must be displayed. Accident avoidance devices and adaptive cruise control are also getting more popular in cars. Clark would like it if there were a temporary block on all lawsuits involving these new devices – just until we can tell if they actually help.
