Nice site, keep it up! I am a local cabdriver and very much agree with what you have written.
Well since I am getting credit for the writing, I thought I should take a moment to introduce myself. I'm the transit man, I run the Seattle Transit Blog and I collaborate here on I am Seattle Traffic. There are many ways to take responsibility for the commute, and simply not taking part as a driver the way I choose.
I take transit to work nearly everyday. Transit has nice side-effects for others. Because I am sharing my road space with other transit riders, I am not adding to traffic. Also, I am achieving my Primary Goals because the bus is safe, rides in the HOV line so it is fast, and since I am free of driving I arrive relaxed. Finally, I can realize my Secondary Goals of the commute without inconveniencing anyone else.
If you are in a position to do so, consider riding traffic and take responsibility for your part in traffic.
