i have made a small update to your AIW
in your original one when ai cars leave the pits and drive to first corner they would allmost come to a complete stop.
i made a small vid about the issue

(sorry for the graphic resolution i know not a much about recording etc>
in the decription on youtube there is a downloadlink to the fix
its not perfect but the cars dont slow down any more in the first corner or bend after leaving pits.
