Amtrak

"AMTRAK lives on subsidies; always has, always will. Americans have limited demand for passenger-train services. Nearly everyone prefers to use a personal automobile, for all sorts of good reasons, including privacy, flexibility, and convenience. None of this is news. Transportation economists have been documenting it in study after study for decades."

"The average intercity auto trip today uses less energy per passenger mile than the average Amtrak train."
