guess its a lot of work to implement a 'perfect' AI.
fast drivers often hav hundreds or even thousands of laps on a track and they r no stupid computers
for making a genetic algorithm improve fast u need lots of individuals (cars) and evolutional steps (laps) and of course a tricky mixing of genes to hand down just the 'racing' qualities. but still i guess it'd take a bigger amount of laps as a good racer'd need to get quick on a track.
anyway..it'd be nice if there was an interface to make a race-bot program.
