    Probably could have built a lot of rail for the cost of R&D on self-driving semis…

      I’m not so sure. Infrastructure is hella expensive and the US government already maintains the highways that make trucking make sense.

        Not necessarily. A 40 tonne lorry damages the motorway as much as 1000 160’000 passenger cars. It will lead to the state having to renew the road surfaces every few years. Rails don’t have that problem, they’ll happily take 100 tonnes for decades.

          The point I’m making is that the government has already decided to maintain the highways, so continuing on is the status quo. If they wanted to make new railroads they’d have to expend political capital to get anything new funded.

            Thank you for the correction! I remembered incorrectly.

      Maybe 2 or 3 single rail lines across the country.

      You guys gotta remember that the US is double the size of the entire EU. I will say that I don’t disagree in that more rail would be nice, but you have to think about this logically.

        Oh I do, it’s where I live. At current costs its about $1.6m(1) per mile, so yea, agreed, probably not much. Will have to check back in 5 years after we see the costs to operate and lawsuits from accidents 😆

        how about historically? we had rail, and it was great. Most of it was ripped up at the behest of auto manufacturers.

          It was mostly the street car systems that got ripped up, not the stuff that carries freight.

            trams were the biggest casualty, but not the only.
