I think scooters are about where it stops working well at a consumer level. Battery swapping exists in the forklift industry but it is complicated and dangerous. Forklift batteries are about a thousand pounds (less than car batteries) and often open cell lead acid (which has additional challenges that lithium doesn't like spills, watering, and gas discharge). In the type of forklifts I occasionally see, the batteries sit on rollers with a side access door and lockout. the tunnel the battery lives in is a little wider than the battery, has a gate that must be reinstalled, and the battery slides around a little during operation. Battery is connected to the system with a flexible connector. Despite the electric forklift battery swapping industry being a lot smaller than the car charging industry it seems to be a reasonably dangerous affair. there are significant OSHA regulations, and a nonzero number of yearly injuries. If you were going to operate a car battery swapping lot, you would probably need: powered battery swapping trucks manned by professional operators, a very flat well maintained driving surface, an indoor charging room, a standardized car battery placement, access system, tie down system, and battery size. you would need to worry about things getting caught in the battery doors, the battery - car cable getting severed, making sure you were perfectly lined up with the access door, and about doing some sort of tie down routine. It's doable but it would be a LOT of work to get right. Batteries aren't as fungible as tanks of gas so you'd probably only use such a system for corporate vehicle fleets or special lease pools.
