I also wonder if some of these lights might ought to be flashing yellow in the night hours - that used to be standard practice in Ohio years ago for lights at the entrance to shopping centers or sidestreets where traffic was not an issue at night. Such lights would flash yellow on the main road and flash red on the side street or driveway.
The Washington Times has run a couple of pieces about this. IIRC, there is an 80% drop in red light citations for each additional second of yellow light.
Long yellows save lives with or without cameras. Short yellows increase revenues if there are cameras. Municipalities choice revenue over public safety. It's that simple.
I remember one of the suckup newspaper's articles pimping for the all Democrat city council One of these clown princes said the city would work hard to get us through town quicker. Then they put in cameras and speedtraps and closed our only freeway for three years.
And there's no recourse. They divided the city into wards with at large votes. The crappy areas of town get to vote for my councilman. Hence, all Dems. All cons.
