I’d categorize it as ballistic flight. While it was able to control its pitch, yaw, and roll in midair, it did not have sufficient upward propulsive thrust to balance out or exceed the force of gravity while airborne. So it wasn’t the propulsive kind of flight, where altitude can be readily adjusted in the sense that we would expect from an “flying car”.

And let’s keep in mind this is 100% vaporware; the cars sold to actual buyers may differ significantly in their design and capabilities from what was demonstrated here. It is possible that the COPVs in the car on display took up the entire passenger compartment.
