So lets see...
Statistically all 16 year olds will have a wreck according to my brother the insurance agent. My two boys did not. they both had a 2.5rs or a WRX as their primary vehicles. I taught both to drive. One was just incredibly careful and the other was just a good driver, but I don't think that had anything to do with it. Teenagers brains just aren't finished developing and some just make stupid decisions. Add that with a little bad luck and boom!
