The essential element for surviving an accident is removing kinetic energy from the driver's body slowly. A stock car is a type of a race car. NASCAR race cars reach speeds of about 200 mph, but they could go much faster if restrictor plates that reduce engine power from about 750 hp to 450 hp were not used.
