Battery swapping schemes have already been tried, theyy all flopped. I don't mind if people attempt it again, as long as they don't fall into the "it failed because it wasn't large-enough scale" trap.

And I'm sure battery-swaps are possible, they're just a really dumb idea. Engineering isn't about what can be done, they're about building the best solution to the problem - and that includes not overengineering it.

As the saying goes: any idiot can build a bridge that stands up, but only an engineer can build a bridge that barely stands up.
