Wow, small world and interesting to see the video. I have met him at autocross, and although I don't know him well by any means, he does not seem like a tool to me. I liked his M3, but at least he wasn't injured. He was in a Cayman at a recent cold and wet December autocross and he drove well. He ended up with the fastest raw time of the day on his last run, just as it started to dry out.
Not having much road course experience myself, forgive me if it seems dumb but would you comment more on why he should have come in for a break? Because of the back end getting loose, then him running off near the Porsche, perhaps his concentration was just not where it should have been?
Also what went wrong? Was he just too aggressive on the bumpers, and it upset the car? Or was it too much throttle too quickly on the corner exit?
I know myself that if I make that many mistakes in a lap I am way overextended.
Losing it at that point in 6 is just the result of getting on too much power too fast, but why did it take so many tries to catch it, add power slowly, feel it slip lift a little and correct and it doesnt need to be a huge deal. He just stayed in the power over the curb and never lifted a little when it got hairy. Watch the throttle graph. Then when he goes off at 11 it is the result of him just following the car in front of him, he missed the braking point by like 50 feet...
Lastly when he does go off at 19 he should have backed off and driven into the giant runoff field IMO, but it looks like he tries to save the "drift" after it is way too late. When I get loose there I just let it carry me over the "curb" there is no punishment for doing so.
I don't know the guy and tool is probably too harsh of a word, maybe a $20K bmw is like $100 to him and he doesn't care, but it obvious the incident could have been avoided.
