huh, interesting question...

I've always wondered something similar with drag cars: it seems like you're always worried about your own work passing, which is pretty decent and as far within the rules as possible (there are times that the chassis or the driver force you to make decisions that are not _exactly_ within the letter of the rules even though they try to follow the intent as close as possible) and then it always seems like there is a decent percentage of cars at the track with certified cages that have booger welds, the wrong size bars, bars in the wrong places... and don't seem to have any problems with tech.
