Yes, most 16 year olds are morons. No, I wouldn't give the keys to a car with a limited slip differential to 99% of the 16 year olds out there. But driver skill is driver skill, there are professional race car drivers 21, 22 years of age that can drive better than anyone on this forum.
I'm 24, and I'd be willing to bet that I drive better than 95% of the 45 year olds out there. It's about reaction time and experience pushing cars limits, and the knowledge of how the car will react.
