Clearly an invention before its time -back then in 1939, there was someone who thought about the danger of vehicles reversing on unsuspecting pedestrians. Surely such an useful gadget should have been of mandatory use many years ago.
But it wasn't until recently, and many people have been killed or maimed in the meantime.
