In science fiction, it is capable of elevating itself some distance from the ground through some repulsion technology, presumably exploiting some short range anti-gravity principle so as to eliminate most friction forces which act against conventional vehicles.
The closest devices are the hovercraft, which elevates itself above a water or level hard surface using a cushion of air retained by a flexible skirt, and the hovertrain, which is a type of high-speed train that replaces conventional steel wheels with hovercraft lift pads, and the conventional railway bed with a paved road-like surface, known as the "track" or "guideway".
In April 1958, Ford engineers demonstrated the Glide-air, a one-metre (three-foot) model of a wheelless vehicle that speeds on a thin film of air only 76.2 μm (3⁄1000 of an inch) above its table top roadbed.
An article in Modern Mechanix quoted Andrew A. Kucher, Ford's vice president in charge of Engineering and Research noting "We look upon Glide-air as a new form of high-speed land transportation, probably in the field of rail surface travel, for fast trips of distances of up to about 1,600 kilometres (1,000 mi)".
