Sure, but there are plenty examples of it being done.

America had an intercontinental rail system in the 19th century. We know that building track over long distances is possible. Even in geographically challenging countries such as Switzerland, robust rail systems are possible. You ever see European trains? WAY nicer than anything you’ll see here.

Yes, America is unique in size, but even large nations like China are accomplishing incredible feats of public transport engineering.

Are the situations identical? No. Will it be difficult and expensive? Definitely. But isn’t America all about being an example for the rest of the world and whatnot?

Something has got to give in the US. Car focused planning is quite literally unsustainable
