I disagree. The run off that drivers use at the first corner at Hockenheim and after the last chicane at Monza in the real world is allowed because the marshals says it means you "go further" than if you respected the boundary of the track. This I don't agree with as it actually allows much greater exit speed and therefore give you an advantage over a driver who is respecting the limits of the track as defined by the white lines and is therefore, in my opinion, cheating. The fact that pretty much every driver does it does not make it right.
