trains save a bit (Score 2, Interesting)

I dislike commuting, but at least public transit gives me the chance to read, emulate vax or make awkward conversation while I do it. I use the WMATA, D.C.-area system. It costs me $140 to ride both ways every work day for a month. If I park in the garage every day, that adds $90. If I tax the bus to the train every day (convenient), that adds $50. At the moment I have a free ride every day. Parking at work would cost me the same $140 a month, and the total cost of that with gas would be around $200. The savings are negligable, until you factor in extra repairs due to more road miles. This would increase the mileage I put on our car by a factor of two.
