From the Heli Cam, it shows that driver B had loads of room and went for the grass purposely, but viewing it from his on board camera it looked like he was rubbing against him and staying on the track was out of the question.
You can see driver A turn to block the line, knowing that the only place left for B to go was the grass. From my experience in the FOX at Aston, I know as soon as you go on that grass you've pretty much had it. Driver A knew this.
Driver B should of come off the trottle, and slipped behind driver A.
I voted for both...
