Im not a circle track racer but I can understand how tough must be to see your car get scrapped because of somebody elses stupidity. but I think the majority of racers understand and respect the work other people put into their cars.
The way I see it, your only competition on the track. if your in the pits and have a problem with your car I will bend over backwards to help get you back on the track so I can compete against you again because racing is where the fun is at! and others have done the same for me when I have had problems with the car.
