I do that with traffic lights...like 13 for instance. If I see the light turning red from a distance, I can usually coast depending on the distance long enough for it to turn green, saving my brakes and gas consumption. Va Beach Blvd. is tough though. Many cities have timers for roads like that which helps keep traffic rolling. Not the Commonwealth.
With traffic I don't have the patience. It would be very tough for me to break old habits.
