If you ride the subway enough in Beijing or Shanghai, eventually you will come to the conclusion that both cities are just way too big. No matter how many subways that you build, getting from one place to another takes a minimum of 45 mins (including some walking on both ends). New York, London, Seoul, and Tokyo all suffer from similar problems -- giant metro systems, but these cities are huge.

At least you can often sit down in Tokyo if you aren't traveling on peak. In Beijing, you never get to sit unless you are clever about your route (e.g. taking the line 10 the long way around when going to West Beijing, rather than transferring to line 1 in guomao). A 1 hour+ trip standing feels a lot longer than 1 hour.

As you say, the solution of course is to not go that far on a daily basis. You can make your life convenient, as long as you are living alone.

That’s why you often end up with ‘cities within a city’ (ala wards, boroughs, districts, etc) and in those cases it’s easier to mentally model the overall city more like a small state.

If you’re sensitive to commute time, you’ll want to live in the same ‘city’ as you work, for instance, or at least nearby. But it will cost you a lot of money, and you’ll get a closet.

If you want the ‘big house with a lawn’ experience, you’ll pick a distant ‘city’ or even another ‘state’ (in this case, a city in a nearby suburb).

Typical case, it’s an hour+ end to end from one side to the other even on the fastest transit for Tokyo or London, and they have really good transit systems.

Singapore similar when it’s busy (which is actually quite a feat considering how small of an island it is).

It’s been awhile since I’ve been in Manhattan, but I remember it being roughly 1-2 hrs too.

Mega cities like Mumbai? Double that.
