    Even under deceleration, most modern cars engines/trans still drag. It's called compression braking. This dragging will cause more fuel consumption than idling in neutral.

    IE: Gravity is using its mystical powers to turn:

    a.) 4 wheels, a trans, and an engine with multiple pistons and rotating mass
    or....
    b.) 4 wheels, a trans...................

    the dragging will just scrub off speed, but if you coasting down to a stop sign or light, then you were going to be stopped anyway, but if the hill continues upward after it is at the lowest level, then the shed speed may cause you to burn more fuel on the way up, but depending on the grade of the downward hill, you're probably getting better fuel cut from decel than the drag from speed preservation. There are always a million "if"s and loopholes fro MPG.

    ^^ Yeah, I drew a frame of a man running on each fan blade. That is him running at idle

    The popular afro hairstyle creates excessive drag which will lower your MPG when used in convertibles or targa tops.
