Hovercar

A hovercar is a type of car that can hover a few feet over the ground, due to some type of ant-gravity unit. Unlike traditional cars, hovercars do not necessarily have wheels. Although some do, because they can convert themselves from standard mode to hover mode. Hovercars are mostly products of science fiction, although they do exist in real life as well. There are some alien species that possess such technology, but it's not that common on Earth.
