You made a clear assertion about the need for cars, regardless of urban density.

But it turns out that actually urban density is pretty good indicator of reasonable public transport. of _course_ there are black spots, rural england lost its trains in the 60s and busses in the 2000s.

But

The british didn't make the tube for tourism, given that they've not built anything transport wise since the 90s (except the Elizabeth line)

Paris didn't make the metro for tourists, because they are french, they're not going to spend money on dirty tourists who get in the way.

the Netherlands didn't make trams for tourists, they can cycle like the rest of us.
