Good points but 1) If your car is in the intersection when the light is red what is there to dispute constitutional or not?  2) Tinting of windows especially the back window should be similar to the side windows for cars and not trucks. In fact, truck tinting should be the same as for vehicles as well.  3) The time between yellow and red should be based on the distance between the lights, exiting freeways, etc. The time lapse between the camera being activated and the initiation of the red light should be adjusted based on the speed limit for that area, exiting, etc.. 4) The length of the yellow light should also be location adjusted as well. and 5)  Yes, there is a possibility of rear-ends but that means you were probably to close to the vehicle ahead of you to react in time.
