That's a difficult one.
If it's a slight crash, I think the flexibility of the unit gives you less impact. You don't have as much ejection and so much sudden, abrupt stop-standing. The coach absorbs some of the energy of the impact.
It all depends how significant it is. If you have a 65,000-pound tractor-trailer coming toward you, let's be fair, it's not going to withstand it. I don't know what you can make that would withstand that. It's horrific. It's very dangerous and nasty.
