I have always been a very firm believer in the safety afforded by seat belts but I am intrigued by a portion of the current COI TV commercial that says that if you don't wear a seatbelt and have a crash "….your body carries on and hits the inside of the car, you stop but your internal organs keep moving hitting the inside of your body and tearing under the force of the impact, etc.". I don't see how wearing or not wearing a seat belt changes the momentum contained within your internal organs that has to be dissipated. Or am I missing something?
