All automobiles, trucks, buses, etc., should have ‘black box’ devices that would record important data that would aid in reconstructing events that may have led up to an accident or incident or yield data that may aid law enforcement in solving crimes or other unlawful activities, such as speeding. The black boxes should record the last 24 hours of vehicle run time. It should obviously be a crime to tamper with these boxes. Some of the things recorded in these boxes should be vehicle speed, angle of steering wheels, gas and brake pedal positions and perhaps other things like the number and direction of forces acting upon the car during a crash.
