In a city near me, when the yellow light times were lengthened back to state engineering standards, the cameras produced so little revenue, an opt-out clause with the cameras' operator (a British firm, BTW) was triggered.
And all studies done that I've read showed that accidents increased at intersections with red light cameras. I suppose a simpleton would say well, they're less dangerous rear-enders, but, well, that's idiotic.
I agree they ought to keep yellow lights at state engineering standards. I also agree that accidents increase at intersections where they have cameras. That’s why I’m opposed to them (along with the blatant money grab issue). I thought you were advocating that lights should be set to a time a lot longer than state standards indicate. I think that’s playing with fire. It appears I misread your original post. I apologize.
