One event we had was a tight gymkhana like affair, for time. The first 200 feet or so required a full throttle acceleration and then hard braking to make a 90° turn (cones). My group did it 3x each, I got slightly better, but was still a laggard. One fellow in our group beat everyone handily.
Then they had one of their guys do it, they claimed he'd never done that pattern before or even seen it. He beat our fastest guy handily. Of course, he knew the car well. But he was a "pro" of some ilk, part of their team.
I don't think I could beat his time if I was there every day for weeks.
The most fun was driving on COTA flat out, we were hitting about 140 mph on the back straight. That got a bit scary, you had to keep at it and then hammer the brakes near the end. Of course ABS makes this a lot easier, and the computers would iron out a lot of other mistakes for us. Driving it with all the nannies turned off likely would have meant a lot of grass.
