Calvin (from Calvin & Hobbes) sitting at a lemonade stand, smiling, with a sign that reads, “Trains and micromobility are inevitably the future of urban transportation, whether society wants it or not. CHANGE MY MIND.”

    The more people try to “innovate” transportation the closer it gets to going back to trains. Driverless cars, for efficiency have them communicate with eachother, to accelerate and brake at the same time, for example. That’s just less efficient and more expensive trains.

      There’s a massive failure condition for your example - sure, autonomous cars behave like trains when they communicate with each other to sync acceleration and deceleration, but they can also separate themselves from the collective to drive you to the door of your home. In the train metaphor this would be like you sitting in your own train car, and the train car separating from the rest of it and driving you to your doorstep.

        Or you could have a train that drops you off either close to your home or close to a bus station that drops off near your home. This would require a walkable city, so it’s definitely not as simple as just building tracks and bus stations. The issue is that Americans are so used to car dependent infrastructure, that when they try to imagine what public transport would be like, they think of it in the context of where they live. That’s why I think so many are opposed to the idea. It’s not an impossible task, it’s just that it’d require money and effort, so it probably won’t happen.

          It also won’t happen because not all of us live in cities. The “fuck cars” crowd never has any solutions for rural locations other than “don’t live there” as if rural areas serve no purpose. As long as farms are a thing there will be people out here, either farming themselves or supporting farmers,and things like scooters and trains either won’t work or only partially solve the problem.

          Anyone who thinks getting rid of cars is a viable strategy in the US of all places is delusional.

            You are talking about a minority of vehicles though. 77% of US personal vehicles are non-rural, hence, fuck them.*

            I also don’t think many people want to get rid of every single car everywhere for every purpose. Most cars are personal vehicles in built up areas and that’s where they cause the most problems and make the least sense.

        oh no, if only someone hadn’t centralized like, a point, say, a station, where people could conveniently access the train of cars…

        they could call it a… hmm… TRAIN STATION?

        You reinvented switches.

        I think you miss part of transportation system that says system. It’s more than one element.

      That not true!

      For some places rail is too expensive or inflexible. So you need driverless cars, but you can make them cheaper by not having so many of them, instead having really big ones, and since driverless is not ready we hire a human to drive for now.

      So sometimes you get buses!

      How to not make a train out of cars:

      1. Remove driver
      2. Make them follow predefined path
      3. Make them accelerate and decellerate together
      4. Link them together for better space-efficiency

      Now you got Certanly Not A Train™.

      Why it’s certanly not a train? Because it still has terrible rollong resistance and low material efficiency.
