So here is one of the ways that we lie to ourselves about our driving habits: we don't think about how much each mile costs us. We calculate how many miles per gallon our cars get. We are concerned about the price of gasoline in dollars per gallon, but we don't think about the price per mile to drive everywhere we go.
We have a Honda CRV which sounds all nice and efficient, but the truth is our actual mpg in the city is 22. That's as good as 1980 mileage. So our cost per mile is roughly 25 cents/mile at current gas prices. So it adds up way too quickly.
