Very gnarly automotive television program. I think Discovery (or one of their sister networks) carries it in the US. Their host Jeremy Clarkson did a pretty neat DVD called "Heaven or Hell" not too long ago. That's worth a watch too.
Last night they had a nun drive a monster truck, physics profs doing burnouts, and grannies doing donuts. They had a marathon on dicovery so I watched it for a few hours.
"If you do encounter someone over there(USA) who’s fond of performance cars they’re only really interested in how much g can be generated in the bends, whereas here those of a petrolhead disposition don’t care at all about grip, only what happens when it’s lost and the car is sliding. Then you are into the world of handling. A world where nothing but skill keeps you out of the hedge."
