The hovercraft was invented by Christopher Cockerell in 1956. He patented it, no-one paid him to suppress it, and large numbers have been built. It is not the hovercar of SF and never will be; it is a "ground-effect" vehicle and can't hover more than about 10 feet above the ground.
Or above the sea ! Many have been used as car ferries, and the Marines love them as assault craft. A vehicle that travels across the water at 100mph and goes right up onto the beach without slackening speed has some advantages.
