I can't see the first video, but if it's the one of the Viper spinning out at turn 1, he was an idiot.
I was at Road Atlanta that day, and the guys had just modified their Vipers and put slicks on them, but had little track experience. Both of them were being too aggressive and making bad decisions all day (blocking people from passing, trying to pass when they shouldn't). The guy came down the bottom straight away, and CLEARLY didn't have room to pass a Vette, but just stayed in it and cut him off in the turn and spun out of control.
Edit: Just got the video to work on Youtube, and that's the one I'm talking about. People were complaining about him and his friend the whole day. I don't know what the hell he was thinking trying to pass that late into the turn.
