Ok I'll detail it betterer.
They teach the various driving aids that cars have, ESC, TCS, radar etc. They outline how these systems work and the effect they have on a car when they are activated. They talk about the issues that may present when these driving aids are disabled, and warn how touchy and potentially unpredictable a high performance car may be when fully unleashed.
They discuss how some cars will have semi slick tires and how those tires have less grip until warmed up, and that you won't get them up to temp in normal driving conditions. They further say that a high performance street tire is a better option for street driving.
Part of the course is teaching awareness about the individuals state of mind and emotions when driving a fully sick car. You may show optimism bias when you're happy and cruising and this may lead to a lack of care or a heightened sense of ability. They talk about driving and the effect emotions have on our actions, and the fact that a high performance car will far exceed the speed limit in a very short time frame, and how these factors increase the risk of dangerous driving.
Braking systems are mentioned and it is said that despite having massive brakes, the leading factor of actually slowing down is the grip between the road and the tire. Massive brakes will endure repeated high speed stops but don't make the car stop any quicker. People see big brakes and think the car will stop instantly, but if you've bought a cheap set of tires the brakes will easily overpower them and you won't slow down quickly.
One thing they talk about is general driving of a hectic car and how you should drive normally. This includes overtaking, you are not supposed to exceed the speed limit when overtaking, yet I'm sure we all know how fast you might go if you floor it past someone.
Another factor mentioned is a lack of visibility in some cars, and that is all I CBF writing for now.
