Every decade someone comes up with a new design for a flying car, or more accurately a driveable airplane. But the problems are still there. Light weight to fly, means poor passenger protection in an auto accident. Wings are big, and folding them back makes a long car -- can you imagine backing this one out of a parking space? On this one the tires barely protruded from the aerodynamic farings. I was surprised he was able to make the grass strip landing.
Best version of the idea I remember, from the '70s I think, took a small four passenger car - a Ford Pinto perhaps, and backed it up to a removable frame containing the wings, pusher engine & propellor, a tail boom for the rudder and elevator. When on the ground you left that portion behind at the airport, and your car drove normally. In the air it flew --- at least somewhat. But, if I remember correctly a test flight crash ended its development (and the inventor's life).
Better to fly a normal plane, and bring a foldable bicycle for ground transport.
