To be fair, products like Lilium with their retractable wings that you can drive to the supermarket like a car and fly like a plane to the next country really muddle the definition of both plane and car.

>the moment it flies its no longer a road vehicle and by definition not a car,
Also, by your definiton, a car that falls off a cliff or does a short jump from going over a hill ceases to be a car during that short liftoff, which is evidently absurd.
