Actually the drivers should consider the distances of cars to the traffic lights in relation to the speed of light and sound in the surrounding air - it would be more optimal if the waiting driver would start honking a bit earlier than the green light turns on so that the honk sound would reach the slow driver at the time the light from the green light reaches them.
(It just isn't optimal to wait the green light to pass two or more cars & then the additional wait time for the slow sound to reach the driver holding up the line in the front.)
