How fast you accelerate off is not important, what is
important is that you be alert to the light change. When the green
light comes on, move! It is very annoying to be four, five cars
behind, and be caught by the red light again, just because the lead
driver is dreaming. And watch out for green arrows too. Many times,
I have seen drivers waiting to turn, but not moving when the green
arrow comes on in their favour.
