'Random' is just that: Random. You dont know when an AI car will suddenly just turn around and go somewhere else. 'Scan' stops driving after it finds all the Navigation nodes. Useful when you want a tour, but not for multi-lap racing. 'chase' and 'flee' only are related to the position of your vehicle in relation to theirs, so you cant pass/get passed. 'manual' causes the AI to just stop after making it to a point, therefore making multi-lap racing not possible. thats why i propose a Multi point pathing system so you can set multiple points in the order you want them achieved, and it will automatically cycle between the three or more points you specify. you can even add an optional lap selection to signify the amount of times the AI goes through the cycle before stopping. just an idea i had, because i dont know how to code these kinds of things.
