The distance between the US coasts is very roughly Amsterdam to Ankara. How often are Europeans doing this journey by train? Coast to coast travel is very common in USA.

Also the idea of scheduling a trip and then a not uncommon European transit strike cancelling it sounds like just what the USA needs. I am delighted our country has defended the rights of interstate travel because I was in Asia during Covid and I quickly realized how scary it was to be on the other side of the state barrier from the airport when interstate travel was essentially halted

Arguments about European transport are tired and fail to account for the geography and population distribution differences between our continents.
