they all rely on the internal combustion engine, as did and do boats. They just are variants of this form of engine. They also all rely on steel and the industrial revolution. Without steel, no trains or tracks, no cars and no modern airplanes.
Meh, if you put a gun to my head I'd say the most important of the 3 is the car as it's accessed by the most people the most amount of time.

A good barometer of how modern a society is can be the car, I'm not saying it's the end all be all, but a way to chart the progress of the society.
