Ok so when you pull over a vehicle would it be possilble to make a script for the car to drive to the side of the road. Im sure many people are having trouble where you press shift and the car stops right infront of you in the middle of the road. Which the causes the AI cars the rear-end your cruiser. Thanks!

I think they use the script that when you begin a traffic stop its like hailing a taxi, no telling how long a new script would take.

It may be possible with the new advanced hook, but until then, just turn the sirens on until he pulls over, then start a traffic stop.
