Race and stunt driver Ken Block is the master of gymkhana. Don't know what gymkhana is? It's this video. In which he propels a car around a "track" like it had been built in a video game and he'd done nothing but play it for ten months straight.

This clip was made to promote the upcoming Need for Speed game, but really, apart from a neat sequence at the start (copying the third-person viewpoint of a game) this is just sliding, screeching and people watching on the internet going "whoah".

And some Slayer.
