The thing is, we already have helicopters. The old "flying car" concept was a vehicle that would drive on the roads between home and airport, and fly between airports. That idea is obsolete. Nobody still thinks they can do that. Instead, the new "flying car" concept is really just a large drone, which is merely a modification of the helicopter, and presumably easier to fly due to computer control of some or all of its functions. A drone may be mechanically simpler as it does not need the complicated pitch control of a helicopter's main rotor. But it's still going to be a very expensive proposition. We will certainly see passenger-carrying drones in the future, and they may compete with helicopters for some uses, but the ordinary Joe won't be able to afford to own or even take a ride in one.
