Looks like you spend almost 20% of your waking hours in a car. I hope for your sake that is part of your job and you are getting paid to do it.I drove 56,000 miles last year.
20,000 in my truck at 17-18 ish mpg average = $4,433 in diesel (3.99/gallon)
36,000 in my car at about 27 mpg = $4,666 in gas ($3.50/gallon)
sweet.
My girlfriend drove another 20-25k in her car.
