No in the midwest they actually police for traffic. The cops will have the highway DOT actually pave little asphault pads when they resurface where they like to sit and take radar. They will get you for out of date registration. They will get you for traffic violations and they do actually send out police to monitor intersections for bad behavior when its bad.

They just don't do anything like that in socal. I've not once seen a cop take radar in socal. Not once. I can't even remember the last time I've seen someone pulled over in socal but it happens probably three times in my view whenever I go elsewhere to visit.
