I should calc out how many gallons I've NOT burned bicycle commuting since 1990...
Lessee... 8 miles/day, let's say 3 days/week to generously account for some driving = 24 m/wk x 52 wks/yr = 1248 m/yr x 20 = about 25000 miles.
An SUV at 15 mpg (city) would use 1666 gallons.
Using current costs... AAA says SUVs cost 60 cents/mile... 25000 x .60 = $15,000.
Hey- I can run out and buy a new car!
