That's Ken Block practicing Gymkhana (forgot that it says that in the video lol). I could probably get the car to slide, but nowhere near as good as he can. I would probably have to stop half way through though, driving like that in that kind of car is really hard on you.
You have to put up with lots of forces, and there's tons to keep up with. There's gearing, pedal control you have to have the course completely memorized and know what speeds your car is capable of in each corner, how much and when to use the brakes, the difference in grip between different surfaces, and alot more. It's alot of work to do all that in a car with rock hard suspension and try to keep the car under control.
There's nothing like the sound of a high hp boxer engine
