Lights seem incredibly inefficient to me. How many times have I been driving towards a green at the speed limit and it turns yellow just in time to force me to slam on the brakes or the gas pedal, all to let one waiting car go? Why not detect my coming and wait for an efficient yellow timing, thus I am not wasting gas and braking unnecessarily? This would substantially improve carbon emissions and brake dust, yet dozens of times per month, I see lights inefficiently block traffic unnecessarily.
