with the new AI improvements by Kunos it is now more fun to race against the AI if you don't have time to race online. So I decided to improve the fastlane and pitlane for the Circuit of the Americas (the mod is out there in the www).
Just copy the fastlane and pitlane to assettocorsa\content\tracks\united states\AI folder. Make sure to overwrite the old files or keep them as backup.
