Public transport is very different in the US than in Europe, and a large part of the reason is density. If that were the only reason, I think we could solve that, but unfortunately, a large percentage of Americans' attitude is public transport is for poor people, especially off the eastern seaboard.

I was alway hugely impressed with the public transport in Europe. Utah has pretty good transport (this project wouldn't be necessary, for example), but it is still difficult to use if you aren't either traveling around or to the downtown Salt Lake City area or have a lot of time you are willing to drop on the commute.
