56.2 cents/mile, to be exact. That's how much it costs the average American to drive these days, assuming you drive a new car 5 years for 75,000 miles, according to the American Automobile Association.
That doesn't include your property taxes that pay for all that road upkeep, of course -- just your out-of-pocket expenses for the car, insurance, gasoline and maintenance. (And one suspects the insurance costs are a wee bit higher here than the AAA average.)
So a 40-mile roundtrip to Logan Airport, for example, costs you an average of $22.48, excluding Pike and tunnel tolls (and parking). Logan Express roundtrip is now $20.
