I wouldn't think so, but it is a term that doesn't really have a solid definition.
I would define the term, based primarily on what—for longer than I've been alive—there has always been someone promising to bring to market very soon; and yet which has never materialized.
Basically, I would define a “flying car” as an aircraft that is relatively inexpensive, easy to operate, and versatile, to the degree that a common man can afford to buy one, easily become qualified to operate it, and can feasibly use it as a general means of commuting in much the same way that the common man currently uses an automobile. Optionally, it may be able to operate like an automobile, on normal roads, in traffic with normal automobiles; though there have been a few proposed “flying car”-type vehicles that lacked this characteristic (for example, the
SoloTrek XVF).
For a number of reasons, I do not expect to see any product appear on the market in my lifetime, that would meet my definition of a “flying car”.
For one, there is the matter of skill and training required to safely operate an aircraft. It unalterably will always be more complex to operate a vehicle that moves in three dimensions, and without solid contact with the ground, than to operate a wheeled vehicle in two dimensions on the ground. I do not believe that an aircraft will ever be as simple to operate safely as a ground-bound vehicle.
There is also the issue that when a ground-bound vehicle suffers a collision, or malfunction, it's already on the ground, while an aircraft is typically thousands of feet above the ground. A damaged or malfunctioning aircraft will unavoidably return to the ground, and if it is damaged or malfunctioning, then this might make this return to the ground unsafe for those aboard the vehicle, and those on the ground below it. For this reason, it will always be necessary for aircraft to be manufactured to a much higher degree of reliability, to be subject to much higher standards of maintenance, and require much higher standards of competence on the part of anyone who is to operate such a vehicle. This will unavoidably translate into significantly higher operating costs.
