Seattle can be tough at least. Really depends on a lot on where you live and where you work. Almost any commute can be done but it easily gets to 2h+ which is just ridiculous.
Seattle is the only one I have personal experience with and I've found it to be pretty good. Usually walking < 1 mile total is reasonable. If you live out in King county things are a little different of course. Are the other cities better than that?
Hence why I mentioned "average-wage" in GP; usually you can avoid owning a car only by living in housing that is out of reach for anyone making <$6k/month.
Most places in the US, housing near transit options is pretty expensive. Further out, where you get to housing being affordable, is nowhere near transit.
