>have even gone a whole month without needing to get gasoline

Every time I consider getting a plug-in hybrid, I'm reminded that they're not for me. Even with daily commuting, I only fill my 12gal tank 10 times annually. I've put, at most, $8000 of gas into my car in the last decade.

I want the geeky toy, but it's just not sensible. If I want to make 50mpg instead of 35, I just have to drive carefully and draft behind trucks.

It's hard to do but I'd love to see some kind of calculator that takes that all into account to figure out one's co2 emission.
