I wonder how many folks are practicing some form of hypermiling without knowing it. For the past several weeks I’ve been employing a few of the most elementary tricks while in my 1998 Caravan. Things like accelerating slowly, not (being caught) stopping fully when possible, and doing the speed limit. I’ve been keeping detailed records of my gas usage and mileage since I bought the Caravan new and it appears that just these simplest things have increased my gas mileage by at least 10%. The thing is (and in some contrast to my post on civility) quite a few folks don’t seem to mind and are often found to be doing the same thing I am. I suspect the high price of gas has changed attitudes on the road as well as those in the automobile showroom.
