Being car-less in America is hard, I lived in a the suburb of a main city and if I was to use transit options to get to work I would have spent 3 hours a day on commute alone. That's simply not feasible. Similarly I used to work a job from midnight to noon (and a year later noon to midnight) and there simply was no feasible transit option for such a schedule, and with the sprawling nature of the suburb carpooling wasn't much of an option either.
