actually ive been thinking this is exactly the win self driving vehicles have been looking for. upgrade, certify, and maintain cross country interstates like I-70 for fully autonomous, no driver vehicles like freight, mail, hell even passengers. maybe that means one lane with high-vis paint and predefined gas station stops and/or some other requirements. i bet the government could even subsidize with an infrastructure spending bill, politics notwithstanding.
there cant possibly be a problem with _predefined_ highways that is harder to solve than neighborhood and city driving with unknown configurations and changing obstacles. i feel like everyones so rabid for fully autonomous Uber that the easier wins and use cases are being overlooked.
