All of the transit systems in Asia (Taiwan, Hong Kong, Bangkok, Singapore, Tokyo, Kuala Lumpur) that i've used make ours seem pitiful and just reinforces how the USA is falling behind in terms of infrastructure. Some are better than others, but across the board they're superior to anything i've used here.

European cities are better as well but tend to be a bit more mixed in my experience.

It's amazing how much of an improvement it is when you use a train and don't worry about whether it's going to show up in a few minutes.
