Anti-gravity is the best idea of creating a flying cars or any other objects that is free from the force of gravity. But under general relativity,
anti-gravity is impossible except under contrived circumstances. General relativity holds on the altered shape of space, deformed by massive objects, that causes 'gravity'. Many scientists involved on anti-gravity for many years but a result being always failed. Another door of creating a flying cars is Parrot AR. Drone
technology. Once see this video.
