This was posted by our own ChazOutlaw on how to get better racing from your AI rides in game.
Pretty simple really. I leave the min setting for everything at 40. I set the max on everything somewhere around 80. Sometimes a little lower if a car is meant to be a piece of shit running in the back. With such a wide range 40-80ish theres a good possibility a car will qualify great, then run like crap come race time or vice versa. A car might start way in the rear after a bad qualifying run. Then run very strong throughout the race. In my offline races it always seems like a car or 2 up front drop through the field. While a couple charge up from the back. To me this seems to work, and be fairly realistic. As an added touch. I set a few cars at MAX aggression. After a few races you get to recognize these cars in your mirror, and if you're a little off pace, you know to get out of the way cause you know the AI/guy behind you is an asshole, and gonna spin you if you give him a chance.
I've set em up this way for a long time. It's hella good racing, though if you get stuck behind, or in front of the wrong guy it can be frustrating.. Now thats simulation.
