When I was in high school, I travelled by city bus while holding two different ultra-low-end programming jobs. I think you are underrepresenting the advantages of having a car.

If I expected to be earning and living on less than perhaps $12 an hour for an extended period of time, I would probably choose to go without a car, likely by moving someplace like Dallas TX (where I live now, and where the local wages vs. cost of living seem reasonably favorable) and renting an apartment very close to a bus line on a major suburban business artery. Judging from my high school experience, from many observations of foreigners living off their science grad school stipends, and from everything I've noticed in my years in Dallas, that'd work reasonably well. But doing without a car would constrain my life in important ways (including job options, education options, and general time efficiency) and I'd be very motivated to find economical ways to reduce the problem, e.g. sharing a car, or getting (and probably learning to maintain) an economical motorcycle.
