I haven't gone through all the posts, so sorry if someone already mentioned this, but it would be really great for the next version if you could add the option to make the ped leave on foot in the interaction menu.
In Jeff Favigano's latest video, he pulls over a car occupied times two, no valid liscence, car is not insured and the passenger doesn't have a valid liscence either but when he lets her go after getting her id and what not, she just hops into the driver seat and pulls away... In the menu, you could have "Ask for ID, Give Citation, Give Warning, Ask to step out, Ask to leave on foot"... or something like that.
EDIT: I know a quick fix for this is to simply tow the car before you give them the citation, but sometimes that tow truck has a hard time figuring life out.
