Its interesting to abstract out the contentious electric car and just try to find consumer or even professional analogies, looking at just physical bulk and practical and safety issues. Swapping giant dangerous things in and out of very expensive life critical safety issues by and for semi-trained to completely untrained consumers at random times and places. There is nothing like it in all of commerce that I'm aware of. The closest analogy I can think of is renting a u-haul trailer for a car, and that is totally survivable both for an individual customer and as a sustainable business model, but not fast, convenient, attractive, cheap, appealing. And a uhaul trailer is enormously simpler than hundred of kilowatt level electrical wiring and lithium batteries that explode when mistreated and weigh enough to kill someone if dropped, so its far too simple an analogy. There being nothing like it in current commerce means its probably doomed because you'd have to roll out something totally new in the world of logistics at the same time as rolling out something new in the world of automobiles. And you can't "cheat" and roll out electric cars first because people will get used to and not mind home charging making it a very hard sell to switch to inferior cars and batteries that can very expensively and difficultly be swapped. The only real hope I can think of for that business model is massive advancement in control semiconductors such that you can make a "raid array of batteries" so a lunch box battery can haul your car to the nearest charger when necessary, essentially the electric car equivalent of a gas can.
