Because we have a remarkable highway system?
What’s with people being so turned on with high speed trains? Travel to a country that has them and “enjoy”. Think all of the money wasted on mass transit boondoggles that mainly line the pockets of unions and politicians. What BS. Shinkashan works in japan because it has its own dedicated lines, no rail “crossings”, many people are concentrated in cities, many people don’t have cars and the distances aren’t like here. Also, they don’t seem to have ferals in Japan so it is generally safe. In America ferals will be attracted to transit hubs and assault you one way or another.
HSR has this going for it: big city Leftists would never have to even stop to by gas in the rest of the country.
Hmmmm ... build their HSR and cut the roads leading out of the cities?....
