Your comment is a fascinating take on perspective. To you it's a fractured, difficult system. To this American, it has been absolutely futuristic every time I've been there. Wish we could get such an awful system anywhere near where I live.
Yup. As an American, I found it quite easy to navigate transit systems every time I visited Germany; most recently Berlin. Especially these days with things like Google/Apple maps transit directions that work more-or-less flawlessly. But maybe it's because I'm used to systems like Caltrain that don't even have a functioning app, and which just randomly cancel trains for huge chunks of the day, or BART, which has an even-more-insane pay-per-distance system than anything I've seen elsewhere.
If you go from the US to Europe, you'll think European public transit is great. If you go from Europe to East Asia, your perspective will change again.
