Dude that sucks!!!
Ouch! That's never good. I see most get knocked out by 4wheelers.
I've almost done that with my quad in the truck.
I don't Break the rules, I Modify them.
I have and have seen it happen. Speed bumps and rubber mats that slide are recipes for disaster.
Good thing I have a tool box in my truck, my x bent the heck out of the toolbox loading the 4 wheeler once. I fixed the toolbox but doubt the window would have taken it as well.
