I think in the sand dunes industry, whats looked over more than anything else is proper belts, seats, and how to wear/adjust them to keep you safe. I see SO many guys just haphazardly clip in a loose belt. If you roll at anything over 25 your belts stretch a ton. Also see a grip of people not wearing the crotch strap... Then I'd suggest probably 75% of cars out there have suspension seats. While comfortable, they compress and expand by more than a foot in a big crash. So if we want to talk about safety, every car should take a look at their belts, how they mount them, how they wear them, the seats, and the quality of the seats. You should be SUPER strapped down. I always say, they aren't meant to be comfortable, they are meant to keep you safe and anytime you sit in a moving car, you should have 5 points strapped in. If your belts and seats aren't correct, helmet or not, you're gonna make contact with one of the bars. You just jiggling around in your seat to see if your head will hit a bar does not constitute for a proper test of belt and seat viability.
