>If everyone started driving the moment they saw the light turn green, the collective traffic would move forward like a train. Yes and we would all have to maintain the same following distance all the time. I know there are some people that do like to follow me at the same distance regardless of whether I'm stopped or I'm going 65mph, but I am going to change my follow distance of cars in front of me depending on my driving speed. You can't have a seamless flow of traffic and a safe speed dependent following distances.
