    One of the dumber statements I’ve seen lately:

    Surveys show that drivers have been changing their habits in order to cut fuel costs. They’re doing things like shopping for cheaper gas or putting less in the tank instead of filling up.

    Actually, in a time of high inflation, it costs more to buy two half-tanks than one whole one.

    This morning I made a real gas-saving change– I biked to work.

    I walk to work everyday. Also, we have cut back on trips to the farm. Trying to keep it to 4 a week versus the previous 6. It’s $10.50 in gas every time they go to the farm.

    I heard something the other day about a habit-changer that saves gas — some sort of black box feedback device recording data on how you drive (acceleration, turns etc) and you use it to retrain yourself, saving maybe 20% on gas used driving the same routes.

    Well, you may have to swim home, at least if you all are getting the rainstorms that the Triangle area is getting hammered with…

    For the last month or so I’ve been trying to change my driving habits to save gas. Slower acceleration from a stop, timing the lights better to avoid idling, more coasting, etc. – My mpg has gone from about 25 to 27. Doesn’t sound like much, but it gets me about an extra 25 miles for every tank of gas, which should come out to around an extra 1000 – 1200 miles per year.

    Actually, filling up a whole tank would be more expensive, because you would have to wait until it was empty before filling.

    Assuming inflation, the price would be lower after a half-tank of use than a full tank.

    But then, what would be the optimal strategy? Some sort of Xeno’s paradox, I guess!
