I keep thinking of Tesla as a battery manufacturer. I don't know enough to know where Panasonic ends and Tesla begins. I know they share the gigafactory and I've seen it a few times on HN that it's Panasonic that have the knowledge and not Tesla, but it seems to me like a vast part of it is Tesla. I do wonder why Panasonic didn't build the gigafactory themselves. I think BMW are on their way to building they're own battery factory but I don't know the scale. But then it would seem that for anyone to be competing with Tesla they'd have to be doing it on the same ridiculous scale. I'd imagine it's hard to keep that kind of thing quiet at least if you're doing it in Europe. I for one still hope the Model 3 succeeds. If it can do 500,000 miles on the battery and nothing else blows up then it'll probably be the last car I ever need to buy.
