Im 20 years old and I guess im a fast driver. ive had one ticket, in one of the slowest cars ive ever owned(96 eclipse gs). but especially now that i have a turbo supra as a daily.. its insane how hard it is to not spool it up. There is just something about the feeling you get boosting down a straight-away and throwing it into a corner at the end. I believe that your ability relies greatly on "Knowing the limits" of your car, and second is Knowing your environment. There is a time and a place for everything. A buddy of mine and I were roll racing down a long straight-away with a bunch of s bends at the end. He had very little tread on his tires and we got to the first bend at about 115. I could feel my tires beginning to slip so i backed off, As he blows past me and catches fifth.. he played bumper pool between the jersey barrier and the guard rail at about 120mph all the way down the hill. How he survived is beyond me but That was a perfect example of "Over-Driving" Your car.
