Flying car huh? Eh. Nice concept, but I'd rather have an ordinary aircraft.
(Personally, I wish I could afford a Cirrus SF50, but... That's in a whole other league, and makes this flying car look cheap...)
Still, $350,000 isn't actually all that much for an aircraft... Though I'll hazard a guess and say it has relatively bad aerial performance given the likely added weight and that rather small wing design.
Also... Pusher props... Some people claim they are inefficient. They certainly make for more elegant designs, but one thing's for sure, they are notoriously noisy.
(Also they make take-off and landing more difficult because if you raise the nose too far, the propeller strikes the ground... Which is... Bad... )
