> You Americans are so funny.

People like you are funny too but its easy to make posts like yours. Density in most urban parts of Japan and Taipei are wildly higher than say a Houston Texas. Again like I said, you are oversimplifying the problem which I get it, its easy to do. I don't think this is as simple as "build the rail, then upzone the area around stations", would happy to be wrong but I think like all of the world there are cultural and historical reasons for the difference.

It would take decades, you need buy in from both tax payers, commercial buildings, retail spaces, home builders etc.

It would be great if you could have a central planner like a China to just build a city with all the infrastructure in place but in places like America, that does not happen and so its a very tough egg to crack. Keep in mind its not just about being hot, definitely lots of Japan and Taiwan are very humid but you are also in city centers that have 8-9x the density of Houston. Lots of things to do and often you are most likely not walking that far, relative for city walking. I could walk a mile in Houston and still have not left my starting spot.
