I do save a lot when it comes to commuting.

The price of gas goes up a lot and it doesnt effect me. I think you may be looking at it only from a strict monetary value. Things to consider:

- Commuting saves you time in the long run. When people at my work bit*ch about traffic, it does not effect me. Weather does not effect me. The cost in saving time is awesome.

- no need to budget time for exercise. My commute is 110 minutes round trip so I need not go to the gym. I head my friends complain about trying to find time to go to the gym.

-Health benefits: A given!

-Mental health: a given

-More productive at work. No need to have "wake up time" when I get there. I am already awake

A lot of the costs you mention are one time costs. Shoes, lights, etc. They will last you. Maintenance on your bike does add up but NOTHING when compared to your car. Buying a tire set for your car can cost around $400 but that goes a heck of a long way for a bike!
