Isn't a vehicle that goes from anywhere to anywhere on your own schedule, safely, privately, cleanly, and without billions in subsidies better?

I don't think individual vehicles can ever achieve the same envirnmental economies of scale as trains. Certainly they're far more convenient (especially for short-haul journeys) but I also think they're somewhat alienating, in that they're engineering humans out of the loop completely which contributes to social atomization.

    I think you'd be surprised. Look at the difference in cost per passenger mile.

    • I'm looking. Comes out unfavorably to cars. Obviously.

      I guess you're comparing the total cost of trains vs a subset of costs of cars, as is usual. Road use and pollution are free externalities after all.

Trains only require subsidies in a world where human & robot cars are subsidized.

As soon as a mode of transport actually has to compete in a market for scarce & valuable land to operate on, trains and other forms of transit (publicly or privately owned) win every time.

>cleanly >without subsidies

Source? The biggest source of environmental issues from EVs, tire wear from a heavier vehicle, absolutely applies to AVs. VC subsidizing low prices only to hike them later isn't exactly "without subsidy" - we pay for it either way

Cars don't work in dense places.

  • Sure but most of the world has a density low enough that cars work and trains don't really. I like trains as much as the next nerd, but you're never going to be able to take a train from your house to your local farm shop or whatever.

    Where trains work they are great. Where they don't, driverless electric cars seem like a great option.

    • Most of the world's population lives in places where trains and public transit works far better than cars. Density doesn't move around, people do.

Is there a magic road wand?

  • No, but roads are paid for by road users (i.e. everyone).

    • AFAICT, the majority (60%) of funding for roads doesn't come from direct user charges...

      Roads are subsidized, free parking (and generally a lot of paid parking) is subsidized, and the sprawl encouraged by car dependence combined with the resulting infrastructure costs has and will continue to bankrupt cities.

      I don't think we should "just only have trains", but the current US transit landscape is absurdly stupid and inefficient.

    • Huh? Last I looked, roads are paid for by the general public, not (car) road users?

better for the person vs better for the people

sure, a private vehicle is better for me, but a train is better for the world

Billions of subsidies? Im confused you talking about cars or trains.
