Red Light Running Retraction?

As with most issues, automated enforcement of red light running (aka photo cop) seems to be a mixed bag.  Here is a new article from the University of South Florida claiming crashes and injuries go up at intersections with photo cop because motorists slam on their brakes and get rear-ended more often.  This finding is inconsistent with Minneapolis’ experience.  Maybe the stealthy mobile unit I wrote about in my last post would get everyone to drive cautiously everywhere instead of the few intersections where they know the cameras are mounted.
