You can see in that very simple, generalized scenario coasting in neutral has a clear advantage - about half the fuel burn of coasting in gear. That's what my own simple test reinforced.
Great. I am not a "hypermiler" and I don't coast in neutral with my DCT, but it is a good finding
I did coast in N from time to time when I was driving MT, but never with an AT. I always thought that the AT are not made for D to N and N to D switch endlesly.
