I don't Understand this exceeding track limits rule. If you chop a turn on the inside line like Seb at Montreal then you are taking a shorter line and cutting track distance. But drifting wide like they where all doing on the final turn is making the track wider. And going the long way round, A car hooked up will do this to some extent. The racing line just pushes you out there. Not that any one got a penalty for putting 2 tires over curb. Make a rule and enforce it every event, Or where is the consistency (Watch Senna movie for that Ron Dennis quote)
By going wide you are able to carry more speed through the corner and also higher speed out of it. Thus make it faster.
No one will ever be penalized for putting 2 tires over the curb. However, if no you leave the track with all 4 wheels (white lines are track limits). Then that is illegal (per the rules).
However, the Federation of Incompetent Amateurs are not able to enforce their own rules, and to further prove how amateur they are, they are not even able to enforce their race,- and corner specific rules for Austria.
