RV seat belt safety

School buses also have shell that will not collapse to 6 inches in roll-over, or after hitting tree branch.
We all did lot of dangerous things in our life. We did survive, but did everybody? I lost several friends in automobile accidents.
Couple of them in parachute accidents as well, so safety doesn't narrows to roads only.
What I would suggest is not to negate the dangerous designs, but simply demand better.
I know better cost more, but how do you put price on your own life and life of your family?
