in the last update there was introduced city traffic behaviour for AI, but it replaced previous one. so now you can't place some cars in freeroam and make them "race" each other, they will drive around the track like they are in the city, so they will avoid crashing even to full stop. i want to have a switch or button to be able change AI behaviour so i can use traffic behaviour for use on regular roads and more agressive racy behaviour to use on race tracks
That's similar to my suggestion. But if you spawn the other cars manually and set them to chase, flee, or random they will still drive more aggressively than regular traffic, but on random they still have rather cautious collision avoidance which should be tweaked.
