> not slow and no unsafe hyper-mileing maneuvers Which hyper-mileing maneuvers are unsafe other than going too slow? I assume there are some or else you wouldn't need to mention it following "not slow." Personally, I sometimes try to use just the right amount of fuel on an uphill such that once I crest the hill, I can maximize the duration/distance that I'm in complete overrun (fuel cut) before my speed drifts too far from the speed limit, and then I correct my speed at that point. Coasting to even lower speeds would improve MPG, but unsafe when followed, so I definitely avoid that. Cresting the hill well below the speed limit, knowing that the downhill will swiftly correct for that, isn't too risky in most situations.
