> But most of the time, when it hits zero, it will go from green to yellow, then you have roughly 3 seconds left. it depends a lot on the speed limit, at least where I live. the yellow light usually lasts a lot longer on a 45 mph road than a quiet 20 mph street. I think having a countdown on the green light would be very helpful, but I worry that a countdown on the yellow light could lead to people cutting the red light even closer. what I would really like to see in the US is a yellow light before the green so I know when it's time to put the car in gear. of course, this could also worsen the "drag strip" effect.
