What I have found since coming to America is that I don't tend to encounter much in the way of escalators at all. There is the rare two-story mall with an underused escalator, but most of the time, I'm dealing with short sequences of steps or just operating on the first floor. Perhaps the reason this is so is that I'm in California, but thinking back on my time in Pennsylvania, I can't say that I recall using escalators much there outside of the very rare trip to an airport. In fact, the experience was so rare in my birthplace that, when my mother had to use one, she was afraid and couldn't manage to time her steps onto the machine to ride one. It just visually confused her.
It turns out that, the good manners I appreciated so much on escalators in Tokyo don't really need to be exercised in the places I've been in America. I can't miss what I'm finding I don't need.
