Simple change your license plate script.

1. Will only work on the built in cars of the game.
2. Does not save the plate.
3. Yes it does work on the police motorcycle too.

This is useful if you just spawn the regular cars in the game and want the license plate to show your call sign/badge, etc.

You have to be inside/on the vehicle to change the plate and your job has to be police, sheriff or highway patrol but as will all my stuff, change what you want.
