    Not really viable - the battery is often heavier than the rest of the car, more expensive than the the rest of the car, and structurally integral to the rest of the car. It’s more like “swapping cars” than swapping batteries.

    It might make sense for special niches like trucking… but in that case it’d really make more sense to just swap the trailer to a different truck. Or use a train with batteries on one or two of the carriages, or run a power line along the track to power the motors, or use hydrogen (which has a power to weight ration that makes diesel look terrible), or use a wind/solar (not everything needs to arrive quickly, and on the ocean you don’t need to worry about slow vehicles holding up traffic).

    Technically, it can be done, but realistically swapping is only an option on motorcycles (those batteries are exponentially smaller and lighter and cheaper, because they get more range by not having to haul a massive battery ever time you leave a traffic light).
