After reading most of the posts, i want to add something to this thread, that has to be fixed in the AIW. A long time ago, Chris (redapg) pointed me to a problem that causes different strange or wrong behaviour of the AI. It's when corridors of the main track and the pitlane are overlapping between the xpitin and xpitout object, what is the case here, as you can see on the below screenshot, where i have marked some waypoints where corridors are overlapping in that area. Chris has written a tutorial about it long time ago, that can be downloaded on his online tools website. Here is a direct link of that tutorial. I would strongly recommend to fix that issue.
