The driver was driving a van ( Tempo traveller ) and when he had to drive through a hump on the road, he slowed down, made sure the front feels went first, then the back wheel and rode smoothly.
Now imagine, if he was walking then he doesn’t have to plan so much, he can just walk over the hump and it will not cause any trouble
The fact that, since he is in the vehicle, and if just rides over it, his back might be hurt, because by choosing to be inside the vehicle he is part of the vehicle and has to undergo what the vehicle undergoes
Same with our body, when we chose to take a bodily form, then whatever impacts the body also impacts our soul. The more you are attached to the body, the more pain we fell we have to go through the hump( humps of life ), without slowing down
