The US, needs to do a thorough review of all transportation systems across the globe and determine which is the most efficient. Once they identify that system, then they need to know the best way of also improving it and incorporating it into our nation's system. Perhaps starting with an underground tube system that can magnetically transfer cargos that would normally be put on 18 wheelers, to relieve a lot of the traffic, more "bullet trains" like Japan has and mass transit systems that run from skyscraper to skyscraper in major metropolitan areas. Any other ideas out there?
We don't live in the rest of the world. Our transportation needs are not like anyone else's. Nowhere in Europe is there a place where towns and cities might be so far apart or where populations travel so much by car. Even Australia, which is of a similar size, has a completely different transportation problem because, often, their towns or facilities are even further than those in the US.
To try to make us into Germany, or France, or the UK won't work. It's a different land, different economy, different people. I'm sick and tired of people telling us how Europe does it. Americans who want to be Europeans should go to Europe.
