The concept of coasting... Think about a red stop light a quarter of a mile in front of you on a 55mph road. You let off the gas and you can easily coast to the light without the engine slowing you down so fast.

Sure, coasting is better if the light is way ahead and you know it takes a while to change. But if it's a short cycle light, the best thing to do is to let off the gas and engine break with downshifts.
