Observation: The cars tend to optimize to get over a challenging hurdle (while it's being worked on, the cars converge to a single solution: which works well), but then are no longer general enough to get over later hurdles.
Unlike those cars we can move in three dimensions, so you're free to find another set of hurdles to overcome. :)
If only we could move freely in four dimensions, as to navigate around events that are difficult hurdles to overcome, such as comet strikes and nuclear holocausts.
that would still be a third dimension since you're just choosing to avoid something entirely within our realm, ever advancing technology is still not advanced compared to forever... or something like that =)
Remind me Fringe!
That somewhat depends on the mutation rate. I have it set to 20% and the cars are optimizing down to big wheels connected by what can only be described as a bar, which means they can drive in any orientation and are clearing later and later challenges quite effectively.
