>fully autonomous, no driver vehicles like freight, mail, hell even passengers. maybe that means one lane ... and predefined gas station stops and/or some other requirements. I bet the government could even subsidize with an infrastructure spending bill, politics notwithstanding. Yup, that's a train. I really do wish US rail hadn't been turned into what amounts to private property. I live along the Amtrak Cardinal line and would love to use it to travel. But the low speed and frequent stops for higher-priority freight mean a trip takes longer than driving and usually costs more than I would pay in gas.
