I too have had many adventures on the track. At the schools I have taken (Barber, Roos), you are trained how to run as fast as possible, while running within your limits. Roos teaches flat out accell, and good braking, so it takes a good car to live through that driving.
I have open tracked many cars in my days. The 69 Mach lived through many a SAAC conventions, running quite hard. Key to always driving home, was ALOT of prep before going, and knowing when the car has hit its limits.
Conversely, now that my Cobra is a track veteran, I have taken a different approach, pushing the car as far as I dare. Yes, I've already broken it and spun it off the track, but that is why we all do it, to go as fast as we can, push ourselves and our machines, and strive to shave that last tenth off lap times. Also, we learn what can break, and fix it so it won't break again!
Good comparison - If you cannot stand physical pain, why play any sports?
