Not trying to be thick but in all american cities ive lived in, there was sufficient transit in the urban core. I understand arguments that it doesnt extend satisfactorily to the suburbs but your claim is much more specific
The only Asian cities I've spent any noticeable time in are Bombay and Hong Kong. Bombay -- I guess it's called Mumbai now -- is a shit show, in every sense of the word. It's one of the largest cities in the world. Transit is awful and dangerous. The only reason my parents took it growing up was because when they were young they were too poor to afford anything else. When we go back now, as rich foreigners, we always take a private driver or taxis everywhere. It's just not worth it.
Hong Kong is a different story of course, due to the British influence and the fact that it was Britain when I last visited. Also, its constraints as a small island mean transit is a must have. And I would agree that it's transit system is better than most American cities.
That all being said, the American cities with densities approaching that of London, Hong Kong, etc all do have rather good transit options. As I stated elsewhere, the issue is the US has no large cities in the European and Asian sense. Our cities are sparsely populated. Yes, a lot of that is due to government policy, but it's also due to the fact that America is -- for the most part -- completely empty land.
Then more people live in the suburbs, but you need a car to get from the suburbs to the city. Then you get more demand for roads and parking in the city and people stop using the public transit even there.
Your assertion ignores the fact that network coverage means nothing if the time to traverse the network just to get from point A to point B is much more expensive, time-wise and economically, than simply using personal transportation to get to where you want to go.
This I totally agree with
I am curious if the intent here is that people should not live in the suburbs or the country, just in cities where transportation can be most efficient.
