In that case, ride the bus. That saves a shltload of gas and you'll likely meet a chick who has less money than you do. Problems solved.
That being said, I have NEVER worried about the price of gas. I fill my tank and thats it. I'm not the kind of person who ponders trivial things like $.60 saved on a gallon. Who gives a crap? If you're worried about $3.60 savings per tank, don't drive a car.
