In saying this DQ'ing yourself should only be done when you know you have broken the rules (me last series @ Sarthe for example), not when you cop engine damage.. I think it's in the GTP rules that you pull over out of harms way and wait till race finish.
Also, stewards will also have to take a look at two other things I found odd. Your overtaking in race 1. Questionable how you went to pass people whether their there or not.
2. You continued to make comments towards Stig even though Oni said to stop. Referring to your commenting during Race 1.
The grass technique is more of a physics glitch how it improves turn in by widening the track and when you time it right improves handling by throwing you into the apex. I for one think it should be outlawed because it's not necessarily against the rules, but the spirit of the game.
I hate negative comments, but I had to give my 2c since I have been lurking this thread I know Dan has been the root of most arguments.
We had a good battle towards the end of Race 1... You'll get there
