Sure, but even Berlin doesn't have Tokyo level of public transit. By my comment I mean that the things GP list aren't the only things that separate SF public transit and Tokyo public transit. You'd also need crazy high population and density too. I don't disagree with GP's list of things, I just think they're not exhaustive. They might be sufficient to get SF to Berlin level of public transit.
