How would cars fly what would keep them flying

Two weeks  ago I would have said flying cars were still firmly in the realm of techno-utopian fantasy, as they have been for decades. Now I’m not quite so sure.

In the coming few years nearly 20 small airborne vehicles are supposedly hitting the market (see table below). Some are drone-like, with anywhere from four to 18 rotors keeping them aloft. Most are fixed-wing craft with propellers that point upwards for vertical takeoff and landing (VTOL), and tilt forward for flight.

if people somehow try puting airplane parts into cars than they wud use the same ways to fly etc.

come closer and become far apart and become steam/gas
