    I don’t think I need to know how air drag works, I just need to know that busses and trains exist. Build up those systems and you’ll have better efficiency than anything requiring cars.

        A lot of hyperloop proposals are pods not trains. Never mind that a little thought proves the concept is only viable with large trains.

      yeah I think you’ve got that vegas loop in mind, that’s not what a hyperloop is. a hyperloop is a train, a maglev train inside a vacuum tube.

        Have you seen how hard it is to convince governments to invest the most efficient and cost-effective medium to long distance mean of transport we have today that has proven itself over hundreds of years?

        Now imagine trying to convince them to invest in pretty much the same thing but with a tiny fraction of the throughput and many times the cost.

        It’s not much of a technical issue. They can be built and will be feasibly buildable in the not too distant future. The problem is economical.

        (Though I must admit that I could absolutely see the US investing in Hyperloops to transport aristocrats instead of high-speed rail for the peasants. I was more thinking of countries here that are republics with half-decent democracies.)
