So you're REALLY ripping on the 1/4 mile guys then....
Autocross is perfect for 99% of us though, really.
It's not door to door... so the risk of trashing your ride is minimal.
I can wake up the morning of an event and decide at the last minute to race.... throw in my tool box, kiss the kids and wife goodbye... and DRIVE my car to the race track. Hang out with my buddies all day... and drive home. There's no commitment... I make it fit MY schedule.
I get the thrill of pushing my car to the edge... and don't have to worry about the inherit dangers of a road course that has speeds capable of seriously hurting me or the car. The closest place to me is Road America... if you don't know... it's a four mile course with huge straights.
I like track fun days there... but if you put a clock on me or put someone in my mirror... the competitor in me is going to push the limits. Then I'm dangerous... to myself and to others.
So the math isn't always right....
But if you want to lend me YOUR car... well then... that's different!!!
