Exactly, with industry-standard infrastructure and plenty of highly-qualified and experienced professionals up for grabs, it is puzzling how they are failing so hard.

My guess is a mentality of "everything is wrong, let's rebuild it from scratch internally and it will be better", ignoring decades of practice and experience.

It turns out that buildings don't know how to build cars. People do.

Which is kind of amazing because their issues of just trying to get cars down the line and trying to fix them after they are built before delivery sounds exactly like the kind of stuff GM used to do that Toyota amazed them by avoiding.
