Justin,
Actually, according to some of the speedvision racers it is not PD faults. As you can see, PD is way in front and taking the fast lane. David Farmer could hit the brake and let the leader his line, since he owns that corner. Farmer is on his rear quarter panel. IMHO.
However, it is the start, first corner, and everybody is there in such a rush, I think the right move is to leave room for Farmer.
My point, however, if he didn't get into the avoidable accident, I think the NSX could have taken the Audi.
Again, that's just my point of view. ICBW.
