As per title this download contains an alternative pit lane AI (pit_lane.ai file) for Circuit de la Sarthe, Le Mans, making the AI take the proper long entry to the pits instead of the shortcut as well as driving properly on the outer lane instead of the middle of the pits.
It's not perfect (the AI brakes a tad too heavily for the first turn in the pit entry) but to me it is better than the default. Feedback appreciated.
