If you need engine braking to slow you down, you're going too fast. Next time go into neutral and start to coast sooner. It takes some readjustment to get the timing right, but when you to you'll see an improvement at the pump.

If the car is in gear, that's not coasting. That's engine braking. Especially a Honda automatic - they programmed it to engine brake like crazy.

You want to be coasting as much as possible. If you're going to fast, then go into engine braking. If still too fast, use the normal brakes. If you're going too slow, give it some gas and then get back into neutral.
