An interesting idea
If we do something like this, can't we setup something in it to get the cars and trucks to use this system to drive themselves around too? Then we could turn this into a kind-of private public transportation system.
They say that even the coal powered energy is cleaner and more efficient than using gasoline powered cars, and hopefully people will come to their senses and start using more cleaner energy concepts, like wind farms and natural gas. They managed to spend money creating the system we use today almost a half-century ago, can't people invest in something that will up the economy, produce jobs, and eventually make nearly everything cheaper and cleaner? The trick is getting around the people who just want everything to stay exactly the way it is when the system gives them what they want.
