The AI spawner in this addon is real fun, but the derby AI is lacking speed and actual hits, right now all they do is reverse into each other, occasionally changing targets, if they'd gain some distance and blast into someone, that would be real cool. And there should be one extra AI, attack player only, that would go great for chases. And cars seem to be turning mid-air. If you could, maybe it is possible to make the wheels flop around when the car has taken lots of damage, as in the cars engine starts to smoke. All-in-all, a very awesome addon.
