This is a demonstration of a car 'learning' it's way around a track. Start it with the green flag. The red and yellow sensors detect a crash and this affect how it tackles that part of the course next time it tries it. It takes a few minutes to learn the whole track but please watch it learn at least part of it. NEW IMPROVEMENT It works faster by not repeating as much and also shows the lap afterwards without any sensors as proof that it has learn the track.
