there was nothing much in the rahal briscoe crash - i think the line belonged to graham - but thats racing. Same with the dixon crash, he gave room to RHR but got caught in the wrong place (outside of turn 1) and got punted into the wall. No stress there from either party.

its going to happen when you have a 170mph straight leading into a 1st gear 100 degree right hander - it has crash written all over it. I'm not aware of any corners like that in F1.
