Somebody has been trying to develop a flying car since cars hit the production line.

With car autonomy, maybe it could actually happen. But with how terrible people drive in 2 dimensions, even if it was technologically and economically feasible, I just don't think we could get people to drive safely in 3 dimensions. We can't get people to drive safely in 2 dimensions.

Anyway. Another interesting flying car prototype about to be released.
