I'm willing to accept that motive batteries will be less expensive in general in the future because of market expansion etc. But does that really mean motive batteries for a specific vehicle will be less expensive?

People in comments are always talking about replacing individual cells from packs, but I don't think that's actually a common service now, and labor and support considerations may not make it a real option either.

(Battery wear seems to be a lot less than people expect as well, more data would be great, but I don't know if that's likely to appear.)
