I'd do it the easy way. Anyone who wants to buy a combo car/plane or car/VTOL-thing can. And anyone who has a pilot's license can fly it in public airspace using the built-in collision avoidance.
Anyone who isn't a pilot can still take advantage of the flight mode, though - they just punch in a destination and the city traffic control flies their car from A to B remotely, lands it, and hands the controls back.
Kind of like having a skateboard and also being able to whistle for a cab when you need to quickly get to Bel-Air.
