Yes we do have them here in Lafayette, LA, but I would not call us backwards. I do not like them. I usually give the camera the ol' one finger salute when I pass them.
NOTE: Houston (one of the five largest cities) had them before we did.
It is funny watching traffic speeding down the road, then they slow down at the red light Camera, and then they speed up after the intersection.
Our red light cameras are also speed cameras.
