Whatever. I know I feel safer when I'm buckled in, and everyone else is, too. I have one of those nifty seat belt cutter/window smasher tools, just in case.
Another personal story concerning that:
A bowling buddy didn't show up one week which caused the team some concern, so the next week everybody was waiting to hear what had had kept him away.
Turns out he was T-boned in an intersection and ended up with his car on its top and he was suspended alone caught by his shoulder harness; a kind soul walked over to the car to ask if he could help and when our friend said yes, the guy cut his strap, slipped his wallet out of his pocket and high-tailed it down the street.
Let's face it, driving has so many risks we can't even name them all, let alone pass laws to try and eliminate them.
