Sister has one, they do not do well in collisions. She was rear-ended a couple of weeks ago. They lady that hit her was going an estimated 10 mph at impact (which is plenty) and it did 7500 worth of damage, and they are still finding more...
That said, she walked away with so much as a sore neck, so when I say they do poorly, the vehicle takes alot of abuse in the collision, but the passengers do very well.
