1st time shame on you, 2nd time shame on me, 3rd time you get punted. This is the way I look at dirty drivers. Alot of them don't like being raced the way they race others. This being said the flagger should have waived the black flag in the heats then at intermission the promoter should have told him that his style of driving will not be tolerated and if he does it again at least a 3 race suspension from the track. This would avoid the other racers equipment being tore up. But if they don't do it then that's when I take matters into my own hands.
