The “flying car” has taken many forms over the past 100 years or so, and none of them have been very successful. Some have been little more than cars with wings, others have just been planes with number plates, many hundreds have fallen somewhere in between, but all have been united by a single trait: abject commercial failure.

There was the Convair Model 118, for example, which was a fibreglass-bodied four-seat car that would tow a pair of snap-on wings behind it. More recently, the Plane Driven PD-1 was a road-going derivative of the Glasair Sportsman light aircraft, basically an aeroplane that you could legally drive home if you needed to. Inventors have iterated on the concept for as long as there have been planes and cars but – for many reasons – nothing has really worked.
