I have been to America and used the bus, the trains, taxi cabs and the subway in and around New York state (it was 1992 so maybe things have got worse).

I'd imagine that would be more difficult way out in isolated communities but there is always room for improvement.

Maybe some could resurrect Detroit's transport Empire by using it as a hub for re-building and improving the public transport system of the nation.

How much do you think the rest of the U.S. is like New York? The whole state of New York is a tiny speck of a place, and it is very densely populated. This means short stretches of travel distances servicing very high volumes of people. I really don't think you are as well informed on most things as you tend to like to think you are.

Things haven't gotten worse public transportation wise since 1992, such a thing simply hasn't existed for the most part before or since then. These "isolated communities" of which you speak are not isolated. They are major U.S. cities tied together by the interstate highway system, home to populations of hundreds of thousands of people.

There is no "rebuilding and improving" the public transit system of the nation, there never has been such a thing to start. Most Cities in the U.S. just have a limited bus system. Building a viable public transportation system in the United States would be a truly enormous task, the cost would be astronomical, and upkeep and maintenance would also be prohibitively expensive.

A train from London to Paris is absolutely peanuts in comparison to the magnitude practical public transportation systems would have to be in most cities. Meanwhile, we have an awesome highway system and automobiles and travel via automobile is extremely inexpensive and far more practical.
