Average cost of car ownership is now $8946 per year according to the linked articled from May of this year.

My friends colleagues don't understand me when I say that money is not the reason I'm commuting by bicycle. Sure it plays a minor role in that I don't want to buy another/second car but that's about it.
I ride because I simply enjoy the rides (for the most part, there's been a few moments). The costs/savings and health benefits are just a bonus.
