When you're sitting at a red light, you have one job and one job only - to pay attention to the light so that when it changes, you can get moving. This
is especially important if you're the first car at the light, even moreso if it's a busy part of the day and there are a lot of cars behind you.
Obviously, I'm not trying to suggest that you floor it the very nanosecond that the green light drops... given the number of idiots who run red lights around
here, this would be pretty dangerous. IMO, the best thing to do is to keep an eye on the light that controls the cross-traffic so that you'll know when your
light is about to change, and when that happens, take a quick look around to make sure nobody's going to run the light as yours turns green. If all looks
good, GO! You'd be quite surprised at the headaches that can be caused by sitting there when the light turns green even for just a few seconds. When I was
commuting to Stony Brook daily, there was a light at the intersection of Nicolls and 347 that was a nightmare whenever there was a lot of traffic because for
the cars on Nicolls, it didn't stay green long and then would stay red for what felt like forever. So when you have 20+ cars in each lane lined up at that
kind of light, and the person in front doesn't pay attention to the light when it turns green, several people may end up having to sit through the light again
just because of their irresponsibility. So do us all a favor, and don't be that person.
