“The CorzineCrushDummy demonstrated how not wearing seat belts can make dummy subject to thrust from the air bag and subsequent flight towards the back and cargo space, with broken ribs, spine and legs.”
Sounds like this fellow would have been better off wearing his seatbelt and having the air bags disabled.
There were problems one time with air bags firing up for no reason. Some people pull out air bag fuse to disable them and rely on belts. The better alternative is the four point safety belts, like in the aircraft and race cars. Nice uniform distribution of load across the upper body and positive retention (except head clonk).
There are stories of people being hurt more by the air bags than actual collision.
