Certainly, the dream of having a flying car has been around a very long time. From Wikipedia, we learn that:
Glenn Curtiss, the Wrights' chief rival, was the first to design a flying car. The first flying car to actually fly was built by Waldo Waterman. Waterman became associated with Curtiss while Curtiss was pioneering naval aviation at North Island on San Diego Bay in the 1910s. However, it wasn't until March 21, 1937 that Waterman's Aerobile first took to the air. The Aerobile was a development of Waterman's tailless aircraft, the Whatsit. It had a wingspan of 38 feet (11 m) and a length of 20 feet 6 inches (6.25 m). On the ground and in the air it was powered by a Studebaker engine. It could fly at 112 mph (180 km/h) and drive at 56 mph (90 km/h).
The day of the flying car is close at hand and it will be powered by a thermopower engine. With no fuel tank and no fuel to weigh it down, the flying car will be the "must have" item for the wealthy. With thermopower engines allowing the public to drive endlessly without having to "gas up" periodically, roads will be clogged and getting from here to there will become the major frustration of drivers in the future. It will become clear to the wealthy that the only solution will be to buy their own flying car to escape the congestion on the roads below.
