a lot of kids have the "If they can do it, I can do it!" mentality, and they don't actually THINK "hey, these guys are pro's that have trained for MANY years"
I've had my run in with people like that. I know my limits quite well, but i suppose a lot of kids haven't had that smack in the face of going upside down in the rain due to hydroplaning into a ditch yet.
(i was going under the speed limit, but the car spun a full 360 and slid into a very steep ditch, it was hopeless, even though i managed to get the car straight)
