I think if people were more willing to put the effort into reporting incidents that break the stcc rules, then we wouldn't be having this discussion!
Not just the blatent wrecking incidents though - the ones where drivers make a mistake and cause an accident, then instead of waiting to be re-passed, they speed on down the road leaving carnage in their wake. If people expected to be reported for these kind of misdemeanors, they would be far less likely to cause the accident in the first place:
They might think:
"ooh, I better be careful here, if I take that guy out, I will have to wait for him, and I will lose lots of places == lots of points"
instead of:
"hmm if I go in hot here I just might be able to get through safely and take the place, but if not, that guy in front will be a good cushion to keep me on track, and if he loses out thats his tough luck"
