The only bit there that I disagree with is the battery swap. They actually did that, and I think it pretty visibly demonstrated what a dead end that approach was likely to be.

Otherwise, though, you are right, and they even prepped for that in the presentation. I always get it done, just not on time. So when this isn't done in 2020... well, 2022 then. They make great cars, IMO, but this stuff is more than a little annoying.
