This is quite interesting. An algorithm that "evolves" to discover the best "car" (2D graphic representation) for the terrain that it's driving upon.
What is interesting about this is less the program than the idea that we can somehow create software that evolves with the tastes of the times and the user. Solutions that anticipate problems and "evolve" to overcome them. Programs that can evolve strategies to solve problems in mathematics and physics, like the Big Bang Theory or String Theory, or how to calculate prime numbers...
