Driving Numbers

Thanks for the heads-up from Marginal Revolution on GM's fuel calculator. So in addition to knowing that our 2006 Chevy Aveo gets 26 miles per gallon (23 city / 32 highway), I can also know that it uses 13 barrels of fuel, emits 2.7 metric tons of CO2, and costs about $561 to gas up every year. Hopefully, it's these other numbers that will get people to make rational choices about what they choose to buy and how they choose to drive.
