Although it is a person that drives THE CAR, the car itself has to work and move.
THE CAR must be ignited and move.
Then [the person] can drive it and steer it in different directions.
If THE CAR did not move, THE PERSON would have to pull the car around.
In the same way, if A PERSON does not do it THEMSELF,
someone has to pull them around [as an outside force.]
However, it cannot be done because it is too hard.
