|Or even a hoverboard?|
In the real world, of course, there are a myriad of reasons for this. Gravity manipulation, if even possible, is still years away, and while more mundane versions of flying cars have been developed, they still run into the problem of being much harder to use than the traditional auto.
In fiction, of course, things can get much more interesting. For example, in Captain America: The First Avenger we see Howard Stark showing off a car retrofitted with "Stark Gravitic Reversion Technology", a feat all the more impressive for being achieved in 1943.
True, it doesn't last very long, but the technology seems well-developed enough to become widespread in fairly short order. That it doesn't can, I think, be explained by this later development:
Clearly, "Gravitic Reversion" is one of the things that S.H.E.I.L.D has been keeping under wraps for all these years - Lola is, I understand, based on a 1962 model Corvette, although of course the hover-conversion could have taken place at any point subsequently. Of particular interest, to me anyway, is that Lola's transition process looks and sounds a lot like the DeLorean's. It's very tempting to conflate the two, and having hover-tech be suppressed by S.H.E.I.L.D for much of the development period explains how it becomes so widespread so soon after it becomes public.

rejected for consideration.
For obvious reasons.
For now, though, flying cars and anti-gravity skateboards remain the stuff of fiction, looking forward to the day when we really aren't going to need roads.
