Actually, no, because the car example is not the same.  The car is more
like a screw driven system in that it moves through a medium, instead of
ejecting a medium to move.

Granted, it rolls over the "medium", but the point is the difference
being illustrated is that it is more efficient if you don't store a
medium on board, but rather use one external to you.
