Because high speed trains are not economical in most of the country. A high speed rail line between Kansas City and Denver, for instance, would simply not have enough passengers to break even with either flying or driving, even in terms of CO2.

Our travel options are flying, driving, and not going. The realistic answer is a mix of all three, each with better technology. Flying in carbon composite planes. Driving in cars that get 50 mpg, maybe still more. Not going, but going virtually.

I’ve noticed in Chicago and D.C. (the only metro areas I go to with any regularity) the trains are very popular.
