I don't understand what you mean Nio the car manufacturer is already doing 100k+ battery swaps a day for passenger cars. I mentioned ev trucks as some mentioned that hydrogen would be easier / cheaper for trucks which I think is wrong as using explosions to move object won't be as cheap or maintenance free as using electricity to move magnets/motors.

I've gone and watched a video on this now and am impressed, it is a lot further along than I knew about.

Consider this as it scales up, though - I can get electricity from anywhere for my car, from a 120V socket in front of a building that a nice owner lets me borrow for an hour, to a 600VDC superfast charger. I can get gasoline anywhere. Heck, there are even hydrogen stations around here now.

I just don't see this kind of thing being scalable to anything other than small urban areas, which are exactly the place they're not needed, because you can charge a car with 300-400km battery range once a week or less and be fine in the city. Where I need my battery swap is more likely to be while I'm on a road trip going for distance. How could I be confident a full battery that's compatible with my car is going to be available for me, and that all the automation to replace it will be in perfect shape, and that the bottom of my car hasn't rusted to the point where this doesn't work anymore?

Actually battery swaps and needing fast charging are for city car owners for rest of the people that own houses they mostly don't need fast charging. They can install solar and can easily charge at home. Most private cars run for less than 2 hours a day. And are parked somewhere most of day I think need for fast charging is mostly about non ev owners not realising they do not need to do things the way they used to with gas cars. Battery swapping is more useful for commercial vehicles that are constantly running
