Try not to send them on patrol too much because they'll just freeze in a spot. This happened to me and the traffic backed up a little too far. About 2 blocks full of cars with no one in front of the police car.
I've had the exact same problem. Just redirect or burn 'em up by shooting at it then tow it. make sure all of the other cars are backed up from the car being shot.
How do you put sirens into your mods and make it turn on and off? please help me. Also, how do ake or edit lightbars. Do i need that zmodeler2 and the $495.00 google sketchup? Please put it in step form.
