Some of the aforementioned driving tactics for mpgs are illegal around here. Drive safely.
On the highway, I'm sometimes the one driving around other cars even while employing hypermiling techniques. This is due to our speed limit being 100 km/h, while my engine typically hits peak efficiency at 115-120 km/h which is also the convention the left lane follows (even at that speed, I keep right except to pass) and which LE tends to ignore so long as you keep it under 120 km/h and aren't tailgating (which I don't do and its a major pet peeve of mine).
"Hypermiling" is a catch all phrase that describes everything from techniques that are safe and completely transparent, to those that are illegal, unsafe, or just plain inconsiderate to other drivers.
I opt for the legal (the mild speeding could be called "illegal," but when I'm driving at that speed behind a police car, along with the rest of traffic in front of him, the shoe doesn't really fit), safe, and transparent ones only. This means mainly avoiding jack rabbit starts, coasting to a red light instead of approaching it at full speed and braking at the last moment, and keeping the engine at lower RPM while staying at (or slightly above) the speed limit.
The upshots, aside from increased FE, is less wear on the car (particularly the brakes) and increased driver alertness and awareness.
Don't lump all who employ hypermiling techniques into the same basket, or assume the inconsiderate driver is using these techniques (most probably are not familiar with the term, are not driving to improve FE, and are more likely just plain inconsiderate).
