To be honest I don´t understand why you moan about the decision now. The rules clearly state where you are allowed to drive, and as you see there were many who knew it and didn´t run wide. (and if it doesn´t give you an advantage why did you go on the green surface anyways)
A cut is not messured by gaining time or not, it´s just about if you stay where you are allowed to stay.
@ Clayton
the problem just is in real if you go wide or cut the inside of a corner you usually loose time.
There have been races in the past here (most 2007 as from 2008 on races were checked for cutting) where the drivers had 2 wheels on the curb and the rest of the car on the grass or in the gravel and they gained time by this. So in order to prevent this we have these cutting rules. And they are so simple to follow....
They did not state where weare allowed to drive... AT ALL we were not told.. if you look where my car is its 2 wheels on kerb and then the kerb runs out.. its a naturla line... EVEN all your drivers had there wheels on this kerb... and the astro turf.. but they did not get penaltys...
