I think that concept is easy arithmetic. If you look at commercial drones, the four propeller design have created a stable platform that makes it easy to use for novices. Ever see those early flying contraptions people thought of before the Wright brothers' first flight? I'm sure whoever that flying car concept belongs to will attempt it. And they'll probably have to innovate to make it more practical. That's really the point.

I think the quad copter type design is actually not as stable as helicopter type design. It is used because the pitch-able blade of the helicopter type design adds mechanical complexity. As size gets larger a single larger fan is more efficient than 4 smaller faster ones. Also controlling the 4 rotors by changing their speed gets more difficult to be fast responding the larger they are.

No since a flying wheel creates angular acceleration which counters the rotor's own angular motion. As I have said it going to be heavy to counter the force though.
Try studying how gyros work. It has nothing to do with the air that drags along with the rotating surface since it works in a vacuum.

The angular acceleration can't go on forever. The angular velocity of the flywheel will reach a maximum point and, at this point, no reaction force will be exerted back by the flywheel.
