Those places are comfortable with subpar transit conditions. There's nothing actually individually desirable about taking the train compared to having a private car take you directly between points A and B, people just seem to shy away from admitting that in favor of pro-social signaling in support of public transit.
Ah yeah, the subpar conditions of ... not being dependent on the car for 100% of your life. The subpar conditions of ... not having to spend hours driving on the highway. The subpar conditions of ... having a choice.
I wonder if there are psychological studies on why Americans en masse cannot even perceive the idea of there being other transportation options than cars and (to a lesser extent) planes. Even though in the rare cases when someone manages to provide a well-planned alternative Americans do use it, see Northeast Corridor (2200 trains a day, 15 million passengers a year, 14% of intercity traffic, replacing most air travel between some of the cities).

Note: it's both funny and sad reading about the state of anything in the US that keeps pretending it's not a third-world country.
For example, Empire Corridor, passenger rail corridor in New York State running between Penn Station in New York and Niagara Falls: "In the 1890s, the Empire State Express between New York City and Buffalo was about 1 hour faster than Amtrak's service in 2013." (Wikipedia)
I guess you've never ridden on the Shinkansen or anywhere in Switzerland. I'd much rather take those trains than do the equivalent drives, especially if I'm the one behind the wheel.
