I mean... yeah?
I think it is China that already have setups to do in place battery replacements? Just drive into a shed and a robot swaps out your current drained battery for a fresh new one (I want to say Tom Scott did a video on this?). I still think that is overkill and wasteful for cars but it makes perfect sense for public transit.
But yeah. Ten or so years in and your battery is starting to meaningfully degrade? Mechanics "just" have to drain it, pop off a few connectors, swap it out, reattach the connectors, and plug it in. Versus a time consuming process of disassembling and diagnosing an engine.
And that old degraded battery? Put it in a truck and get it recycled.
