not in the us because train/bus is horrible way to get around and it cost just as much or more for a longer trip.
planes are main transportation if its long distances.
I wanted to take a train 90 miles from here. I would have to go all the way to Chicago (like 5 states away) just to get to my destination 90 miles away.
I like the bus, but once people start using it more they will upgrade the security to be just as harrassing as it is on the planes. Who knows after that
