I have read a lot about this car and also various other flying cars from other makers. This one is still a long way from flying. And I am not really sure it ever will. BUT good on them for giving it a go. God likes a trier as they say.
The biggest problem is that the TPTB do not want people to fly. They lose control over you. Having the ability to go anywhere is not what they want. Besides they still have roads to maintain, who will pay for that ?
The car/aircraft shown in this demonstration is certainly an upgrade of what I have seen before.
