yeah as far as passing and crowding it seems, from what i have seen in person and in videos, that the D1 guys are pretty respectful of one another...they get close and try to match front wheel with back wheel while going into or through a corner but it seems they understand and recognize when to back up and when to close in...then again these guys do have ultimate control of their cars...amatuers doing the same thing would bump 9/10 times is my guess..lol..
