Earlier quoted context omitted.
What purpose does selectively quoting an article serve? I don't see the point (if any) you're making here.
The quote is a representative sample of the article, an article which is illustrative of Musk's apparent disinterest in (or ignorance of) the Toyota Production System. I've never seen a Musk quote that clearly demonstrates he has any idea how TPS works or what he is really competing against.
"The car industry thinks they're really good at manufacturing and actually they are quite good at manufacturing. But they just don't realize just how much potential there is for improvement. It's way more than they think,"
Or
"Musk acknowledged that Tesla had been "a little overconfident, a little complacent" in its ability to crank up production volume for battery packs - its specialty - at its massive battery gigafactory near Reno, Nevada. "
But yes, I could have make Musk sound like an idiot too. I chose not to needlessly take someones words out of context for click-bait. You're free to have your own opinion, and Tesla will keep selling more cars I guess. I'd like to buy one but I cannot afford one at the moment..
