They are working on a highspeed rail system in my area for St Louis to Chicago, but that doesn't solve most of the problems.
Highspeed is great between major cities. The problem the US has is that most people need ways to travel within the cities. Some US city metropolitan regions are larger than some european countries. I live in the St Louis metro, which isn't really all that big compared to other cities, yet we have 8,458 sq mi (21,906.1 km^2) of area, with 2.7 million people. With how things grew up, most people aren't able to work within walking, or biking distance of their homes. It isn't uncommon for people to be a half hour or hour away by car.
