Even better with trick for AI traffic in track days! I found that it`s possible to have both ways traffic if you copy the "pit_lane.ai" from the "\layout_uphill_wet\ai\" and rename it to "fast_lane.ai" in "\layout_drift\ai\". Then you need to make a simple pit lane in the game with the developers app and Voila - the traffic starts going for the whole 12h. Better to turn off the damage, tho!
