I don’t see why it’s so hard to comprehend that if you are laying on the metal floor of a van, legs tied and hands tied behind back with head pointed towards door that if the driver hits the gas from a standing stop that you couldn’t possibly smack into the door head first and snap your neck vertebrate. The neck is a weak point on the body. Could’ve happened this way. You’ve got all the weight of your body below your neck and that adds to the force with which you would hit your head. What’s the weakest point between your head and the rest of your body? Thank you.
Not due to acceleration. Have driven numerous medium to large size vans with delicate cargo. They do not have the acceleration capabilities to slide a person across the floor with much force. Now braking, yes. That could happen. But it would be a front wall.
Nah. Not enough momentum to affect things. It would be better, if the Convict were on the floor, to have him facing forward, and then, SLAM on the brakes!
