in a 2 wheeler you get thrown off
In a car, you are in a cage and you roll inside of it.
4 wheeler or snow machine ,the darn thing rolls over you..you are the crumple zone

We had a VP in Utah get rolled over by his quad, from VP, top of the world of a major Sofware company, to quadriplegic in the blink of an eye..

3 things scare the **** out of me, I'll never even try em: Quads, snow Machines and parapente chutes (low wing loading= high risk of collapse from gusts or fancy maneuvers )
