Public transportation is _really_ bad in some places. Where I live, sometimes you can be two hours later than the schedule would suggest relying on public transit. I suppose you can then go to work 3 hours early to compensate. But it sure doesn't make it easier.

And I live in a reasonably sized city, it can be even worse in other places, like no bus route at all.

Our society is not set up for poor people, let alone homeless people. _everything_ is harder when you are poor, and an order of magnitude more so when you are homeless.
