I read so many trivia and reviews that police cars are the wrong color for the location. This isn't a mistake, it's intentional to avoid confusion. It can create a tremendous legal liability issue if legitimate local police cars are used, as those who require emergency assistance have been known to approach actors and stunt drivers in police cars that are identical to local law enforcement vehicles. "Sorry, I'd love to stop the man from shooting at you, but I'm not a police officer!"
