Good post, but I disagree with this. If you are engine on coasting down a hill, then slower does not take less energy to travel the same distance. Also, going slower up a hill does not always take less energy. If you go 1mph up a steep hill, enormous amounts of energy will be wasted just maintaining position on the hill.

There is a balance of engine efficiency, speed, wind resistance, and rolling resistance.
