> There is a major difference between Western Europe and the US: The former has a population density of 184 people per sq km, whereas in the continental US it's 43 per sq km.
Wrong, the population density of a country is irrelevant. People aren't uniformly distributed over an entire country's area. A low density usually means a country is big and has a lot of nearly deserted areas, which is true of the US.
> Moreover, the major cities in the US have more distance between them.
Yet another simple average that has no bearing on anything relevant. NYC is far away from San Francisco? No shit.
> The result is that even if you increase the density in some US city, the people in the surrounding areas will still need cars, and then will come to the city in their cars because it's the only city within reasonable distance of them.
Yeah, that's literally the same everywhere else in the world. Therefore, the argument is moot.
> The subset of the US where that isn't the case is basically the New York Metro Area.
Obviously untrue.
> If you draw a 250 mile radius around Rotterdam, it contains Paris, London, Frankfurt and the entire countries of Belgium and Luxembourg. If you draw a 250 mile radius around Portland, Oregon, the only major city is Seattle some 175 miles away and mostly it contains a lot of trees.
Yay, cherry picking! In any case, now explain why despite sufficient density existing in a lot of places in the US there's 0 investment into mass transit there either? It's almost like density is not relevant at all when it comes to the US, weird.
> And then even though they're the sort of people who like mass transit and build it, the large majority of people there still don't use it.
Uhuh, "the sort of people". Let me make one thing clear. There is no place in the US that has any sort of a half workable mass transit solution, with maaaybe NYC as the sole exception as something that can maaaaybe aspire to be half as good as your average European city. So if you're telling me Portland, Oregon built mass transit, then your idea of mass transit is very different from what that actually means.
