old3eyes: I believe in the US in the quiet time traffic lights go flashing amber which means the normal give way rules apply. Speeds up the flow at say 3.00am in the morning.. Here when the lights go flashing amber no one seems to know what to do but they could always be educated..
Brilliant idea. My issue as a motorcyclist is my bike does not set traffic lights off, so if its a night, or a quiet road, or when I'm unlucky enough to be first in the queue, no matter how long I wait the lights will never I green. Just 3 hours ago I waited 4 full phases of the lights to turn onto Tinakori road until someone pulled up beside me into the going straight lane which then changed them to green!
