I am trying to understand what are the influences on the game engine and AI when controlling various cars on the same track. As an example I like to use Longford 1967 for most of my car tuning testing. The long straights, unforgiving 100% commitment braking zones and bumpy undulating track surface make it like a mini Nurbergring for car setup. My main question is what causes the AI to stick to the racing line in some cars but in other cars have them take liberties with the braking points even appear to try cut corners in other cars. It makes trying to drive with the AI frustrating as in some cars they lap very well, while in others they try cut some corners and end up crashing, Is the track missing some important data or are some cars missing some important data, and if so - what data files of the cars or track should I be making changes to? Thanks in advance.
