A High Performance Driving Event is usually a great place to safely learn the limits of your car, on a track, with a helpful and professional driving instructor. Unless your instructor is this asshole.
As this was the first time the owner took his MazdaSpeed3 on the track it's surprising the instructor freaked out. Seriously, he seems to have done nothing wrong other than a couple of jerky shifts. Luckily, the student got it all on film, uploaded it to YouTube, and the instructor's boss saw it. Guess who won't be frightening newbie drivers at Thunderhill anymore?
