Battery replacement also seems like a huge sustaining capital cost that never gets figured in when looking at the costs. What is the lifespan? Maybe a few years if you are lucky?

I know they've considered that for the cars, but I haven't heard anything about that being a serious part of the game-plan for a while anyway.
I do agree that that would take care of the issue of having to sit around for an hour or two while it recharges.
That said, battery lifespan on the Teslas at least doesn't appear to be a huge concern.
