Aaaaand we’re back to reinventing trains. There should be a name for this phenomenon. How long do tech folks discuss how to improve transportation until they attempt to reinvent trains?

Come to think of it, wouldn’t it be much more logical to automate trains first?

  City trains are often automated[1]. Have been for decades as far as I know. Long distance or regional trains are often driving on very very old train networks. I don't know much about trains, but I guess if you would build a new train line now you could also automate it. But that is just a guess.

> we’re back to reinventing trains The term you’re looking for is armchair logistics. Trains and trucks have been competing for a long time. Autonomous trucks, even in convoys, even where freeways have RFID signs, are vastly different from trains. You don’t need to lay and maintain tracks. You’re not limited to where tracks go. You can assemble and disassemble on demand.

  Yet you need to lay and maintain roads, you're limited to where roads and RFID signs go. You also have the added inefficiency and environmental problems of rubber-to-asphalt contact. In addition, you need to carry batteries which means even more inefficient transportation.

    > you need to lay and maintain roads, you're limited to where roads and RFID signs go No, the roads and signs are already there and being maintained.

      You could probably save a lot on maintenance if you didn’t have trucks driving on the roads.

Stop being moronic. Different transportation mediums exist for a reason. Trains in the US are currently suited for long haul transportation at which they excel at. We already tried running rail lines to warehouses and distribution centers and determined trucks were a better form of last mile transportation. Do you think that no one at UPS, FedEx, Walmart or Amazon has ever looked at how much more efficient or what cost saving they could get if "only they had a rail line to their warehouses verse a road?" What the discussion is looking at is making a micro improvement to what we have already tested as the better method of delivery, trucks in this case. Where the issue is coming about is we are trying to build autonomous actions into a hybrid roadway verse dedicating a portion of a roadway to autonomous driving. The article states the following: "Trucking was supposed to be the ideal first application of autonomous driving. Freeways contain predictable, highly structured driving scenarios" When sharing the road with human drivers this statement makes no sense as all. Vehicle's are their own entities with no connection to each other outside of the road, signage and defined lanes.
