That could've happened to anybody. That track gives you little room for error. I like the thought of the desert or grass when I make a mistake, not a steel fence 10 yards off the track. He should've waved the guy by.
He was having problems with that corner on a consistent basis. Race tires and grass, Mr. Fender meet Mr. Armco. Depending on the track, although I dont think he hurt the armco, you can be held responsible for repairs to the track equipment.
Clear case of running out of talent. Nice to be in the lead but you got to have a feeling for when you're pushing beyond your abilities and he just kept on messing up that turn (and many others). Nice driving in the camera car, just stayed back and saved the tires for when the Corvette ran off.
