Do you have a friend or somewhere that you could temporarily leave your car? When I was trying to decide whether to go car free or not, I parked my car at the garage at my office and pretended like I didn’t have it for a a few months. I ultimately decided to keep it but I still rarely use it (I bought it new in 1999 and have put 45,000 miles on it in 13 years). I don’t have any parking costs or a car payment and insurance is less than I was paying during my experiment to use zip car or cabs on the few occasions that I needed to. There are months that I don’t drive at all and months when I drive more. But it sure is nice to be able to take a spontaneous ride or to visit friends who aren’t metro accessible.
