High-speed rail? This isn't Europe, with everything in an area less than the size of Texas. Just how many not-metro towns do you know with rail shipping? How many Wal-Marts, Krogers, shopping centers, electrical-generating stations (other than nuclear power plants) have a rail loading dock?
And ... how much does the cost of manufacturing rails, locomotives, and cargo cars add to the "savings"?
You want to save Mother Earth? Then design, build, manufacture, and use the most efficient methods. EV, which requires major investment, major pollution, and child labor overseas, is not it.
