A flying car would be so extremely cool, let's call it one even if it's not one (and nobody's going to use it anyway)

The 18-Rotor Volocopter Is Like a Flying Car, But Better | WIRED

"OK, fine, strictly speaking it isn’t a flying car, because you can’t drive it on the ground, but who cares? It flies."

I saw my first vaporware flying car some time in the late 1940’s, by which time the idea was already old hat in Popular Mechanics. It’s one of those ideas that’s entirely wonderful in concept and would be terrifyingly awful if any significant number were actually in use. Imagine a rush-hour expressway full of airplanes, or everybody trying to take off at once when the opera lets out, eighteen rotors or not.
