How do you figure? Red light cameras decrease frequency and severity of crashed at signalized intersections. crsreports.congress.gov/product/pdf/R/R46552

There is some increase in rear ended, but those are much less severe than right angle or pedestrian collisions.

Cities adjusting the dilemma zone, or increasing speed limit; is a problem with revenue usage of red light cameras; and revenues should be going to victim funds. It also seems to be a uniquely USA problem? That could be a taxation and funding source issue.
