Genetic Algorithm Breeds cars

I let this genetic algorithm run a few nights in a row to breed the "fittest" car for this course.  The difference between two nights isn't as dramatic as from the beginning.  The cars started pretty squat and then turned out spiky, and then rearranged he spikes a little.  I think that the spikes help when the cars tumble to let them right themselves again.  It may also have to do with weight distribution.

3402 generations in human terms is about 85,000 years, so these cars have gone from hunter gatherers living in caves to spaceflight.  Although really they have just gotten pretty successful at running this course.  The best performance ever was around 1000 generations and they have just been spinning wheels since then.
