So, I have come to the issue that I know the driver is either wanted/ vehicle stolen etc. So lets be honest we know the driver will 99% try to evade you.... So what if you could give the command over the Loud Speaker stating "Driver get out of the car with your hands up and etc."  I think this would really help with the annoying getting out of the car and having to run right back to the car because they take off. If there is something like this that already exists please let me know!

As far as I know, there aren't any voice files for yelling those instructions. What you can do though, is simply not walk up to their car but stay next to your own car and order them out at gunpoint. Arresting people works with peds in vehicles too, they should just get out and start the regular animation.

Not really sure why you'd walk up to the window, knowing the occupants are wanted felons. Order them out at gunpoint from behind the driver door, preferably with backup standing by. The gunpoint exit mechanic is brilliant, and was designed for just what you describe.

On that note, I do agree that a script for playing felony stop commands would be nice.
