Those Germans are Frick'n Smart!
I was watching one of my favorite show Fifth Gear and discovered that the germans at Volkswagon created a Golf that can actually race around the track as well as any human can! You just lay out a bunch of cones to describe the track like in a autocross event. The car does an training lap at around 25-35 mph to calculate the fastest line. Then its able the race around the track. In the test, the car managed to get within 1 sec of the human racer's time even with an extra person in the car. Not too bad, i'd say.
