For me, it wasn't the wind, another car, or anything rusty-screw-worthy... I just got lazy and sloppy and goofed up all by myself in the dirt S-turns, tagged a wall and broke my front shock. Very disappointing, but can't blame anyone or anything but myself.
I think Cabby may have had a car actually _land_ on him in the esses on lap 1. But I might give the Rusty Screw to Paul, who was in podium position with a great race setup in the first race and wound up on his roof.
