An article from Popular Mechanics about saving lithium-ion battery life. Also, Hypermiling. Does anyone here drive like this? It seems to me that it's most effective in places where you have a lot of highways and traffic congestion, but I live out in the boonies and I seem to have saved ~10 to ~15 miles per full tank, maybe even 20. I haven't done any exact calculations yet, but I'm "ahead" by about 7 or 8 miles according to my odometer and where my dashboard gas gauge is at.
