I can say I have crashed just like you and with open go karts and I'm lucky I never received a single scratch. I've also taken a little smack against the wall before that made my entire right side sore to the touch and that hit wasn't even enough to bend the wheel. All I was doing is saying that going from full race speed to a sudden stop I'm happy I had my full containment seat and head/neck restraint because I wasn't sore or anything. And your right some people might not be able to race for a year and that sucks and everything but when their family is happy seeing that what they race is trying to help protect them then it should be worth waiting a year. A friend of mine puts it great with helmets area. "Do you have a $100 head or a $2000 head"
