Battery & battery replacement cost is a big piece of ammo for people who fight non-combustible automotive energy sources, so fantastic as always.

I'm interested to know what sort of contributions Musk & Co have been able to make with regard to battery efficiency and longevity in their time with the Tesla line. That, to me, is the big missing piece to take things from "sure, it could work" to "ok I'm ready to switch" for many.
