Steve, I really enjoy reading your editorials about non-computer subjects and hearing about life on the farm and other things like your Prius update.
I live in a banking town that is vastly conservatives where most vehicles on the road are luxury sedans and SUVs (although $3 gas is starting to change that finally, even here). I often hear comments around here like global warming is a farce and how people will use as much fuel as they want to since they can afford it and it is their money to spend (which is true, but is irresponsible to me).
In 2004 I had a contracting job where I was driving 120 miles roundtrip each day and that is when gas started going up. When it got to $1.75, I decided it was time to park my 2000 Explorer and get something economical for a daily commuter. I bought a new Toyota Corolla because it was cheap and rated at 32/40 (city/highway). That immediately cut the weekly fuel cost in half (although offset by additional insurance for 2 vehicles, but still a savings overall compared to driving the Explorer exclusively). The purchase price was not a factor since I would have needed to get a new vehicle anyway since the miles on the Explorer were getting up there (not to mention that the initial cost of the Corolla was half what the Explorer was 4 years earlier).
Today I have a 20 mile roundtrip commute and still have the 2004 Corolla and can get 2 weeks out of a tank of gas (fill up for about $32 at $3 per gal). It still gets about 30-31 mpg in the city and that is with aggressive driving (necessary in this town to keep from getting run over). I still have the 2000 Explorer...it is driven a couple of thousand miles per year to the home improvement store and hauling my labrador retrievers to the park occasionally and other short trips where something needs to be hauled or a trailer towed.
So I'm saving money on gas that I can spend on things I would rather have or things I would rather do anyway, and at the same time making a positive difference (albeit small) in the environment and our nations dependence on foreign oil. Now if we could get everyone else to think like that...
If it was easy, everybody would be doing it!;)
