I think there are two different things though, and in the UK the bar is (mostly) just a practical one.

Lots of my colleagues cycle to work, because the cycling infrastructure is great (both from Cambridge City, and from my employer). For those along the Guided Busway corridor, quite a few get to work like that because it is convenient.

Step 1 is to make the public transport good enough so that it is at least as good as taking a car. But the US has Step 2 - convince people that they aren't looking poverty stricken if they take a bus.
