Does the AI use the same physics as the player? I ask because I did at 50 lap race at a track with the Mini's. By lap 27 my front tires were solid yellow and I'd been giving up a few tenths per lap to degradation. The AI cars never seemed to slow (confirmed post race looking at lap times). I took a slightly above half fuel load and pitted but the AI didn't ever pit. So do they run the same physics as the player? Also, when do they decide to pit?!
