Also a huge number of people in the US travel to places that are walkable:
- Disney World
- Las Vegas (The strip is anyway)
- DC
- NYC
As an American who has experienced Deutsche Bahn, National Rail, and Amtrak, I’ll stand by Germany and the UK having pretty good inter-city rail compared to us. Lübeck and Bath are the cities there I’ve been with the worst public transit, and they would be well above average in the US.
I haven’t been to Switzerland yet, but it’s not shocking to hear the public transit there is all-around better.
