Here is my video of AI fails at Beez with the GTL-Mod. I have not tried other mods or Simbin cars.
There is a tricky corner to take fast for both human and AI drivers. At 2:04 is my fail and three AI drivers and later in the video at 3:29 loads more AI drivers get it wrong in spectacular fashion.
This seems to happen more in free practice than in the race. I guess the AI drivers are more cautious in the race. The track builder must be able to change this setting. I would love to know how to do this so I could make the AI drivers take more risks at other tracks.
