Is It More Efficient To Coast In Neutral Or In Gear?

What uses less gas? Coasting in neutral, or engine braking? Of course, the answer is it depends. A simple example? If you're approaching a red light, and know that it's going to remain red, engine braking will slow you down without using any fuel, and will be the most efficient option. If you know for a fact that the light is going to turn green before you reach it (which, you don't, but hypothetically), then it's more efficient to coast in neutral and maintain your speed, then get back on the accelerator once the light has turned green.
