Humanity has been promised a flying car for about as long as it has had cars in general. The dream has shown up in science fiction, world's fair exhibits, and a steady stream of prototypes that made headlines and then quietly disappeared.

The gap between the promise and the product has always been the same story. The technology wasn't good enough. The regulations weren't ready. The money wasn't there.
