Watch neural-net racing cars learn to drive

It's not quite natural selectioncreator Johan Eliasson picks which cars get to reproducebut there's something amazing about these virtual cars learning to drive around a track without even knowing they are cars.

Teaching a neural network to drive a car. It's a simple network with a fixed number of hidden nodes (no NEAT), and no bias. Yet it manages to drive the cars fast and safe after just a few generations. Population is 650. The network evolves through random mutation (no cross-breeding). Fitness evaluation is currently done manually as explained in the video.
