The shot at 2.20 is pretty cool, hahah. Trippy seeing a steering wheel in the cockpit.
The take-off at 1.50 is a bit iffy. You can see it's not that stable in yaw because it's so short - and it already has some pretty large tailplane surfaces. That would be the main challenge I'd reckon. And the requirement for as short a wingspan as possible. I wonder what the car/aeroplane runs on. Seperate fuels presumably.
Test pilot Reuben Snodgrass flew the prototype, registered NX90850 for the first time on November 15, 1947 but it made a low fuel forced landing near San Diego, California on November 18, 1947, while on a one-hour demonstration flight, destroying the car body and damaging the wing, although the pilot escaped with minor injuries. The pilot reputedly took off with little or no aviation fuel aboard although the fuel gauge he was looking at showed full fuel, but it was the automobile fuel gauge.
Yeah about the only benefit is that you could drive it home from the aerodrome to park it at your own house. You aren't going to drive this to the shops, and you sure as hell wouldn't be allowed to take off from anywhere that isn't a regulated aerodrome.
I don't think flying cars will ever happen. There's enough people who can't drive on a 2D plane, without complicating things and adding a third. The only way that would ever come to be is if every flying car was autonomous and linked up to a massive communications system.
