I've been watching some videos of rally racing over the last week. That is a crazy sport. As I understand it, the cars race one by one over a specified course with varying terrain to see who can get the best time. Each car has a driver and a navigator, who tries to keep the driver updated on which turns to take and what to expect while the driver concentrates on keeping the vehicle upright and pointed in the proper direction. Here are some pictures I nabbed off the net.
I don't think I've got the innards to drive like these maniacs, but it sure is exciting to watch. If you like cars at all I suggest you do a search for 'rally racing' on Youtube and check it out.
