On the joys of public transportation

I love public transportation. At least in concept. In practice, there's usually a lot left undone, unfinished, half-done or patchy. Bombay (aka Mumbai) is an example of a system that serves the population well, but suffers from overcrowding. People commute everywhere by train and/or bus and in their hustle and bustle miss out on the simple joys of public transportation. Atlanta has MARTA.
