We have them. I'm not too concerned about them. I don't know...it is kind of like radar detectors. Who needs a radar detector if you are going to drive the speed limit? Or do you need it because you want to speed & know where the cops are so you can slow down? (Like my husband) Same with the cameras. If you don't run lights then nothing to worry about. Speeding & running lights are against the law. Guess it is all about each persons perspective on right & wrong.
