A) It has been shown that yellow lights with such cameras are very often set to a yellow duration briefer than generally accepted engineering practices to increase revenue *1

Then create and enforce laws that require a given yellow light timer for a given speed.

B) They discourage a rare misbehavior, actually running red lights, whilst causing another to become common. That is slamming on the brakes even when it isn’t safe to stop. Exacerbated by A. Better slam on the brakes when it flicks yellow even if you are way too close to reasonably stop whilst going only the speed limit.

Guess you’d better leave a safe stopping distance between you and the car ahead of you. If you can’t stop quickly enough to not rear-end someone slamming on their brakes, you’re following too closely. Kids and animals run into the street all the time.

You and others like you are letting the perfect be the enemy of the good.
