Well, I don't think the logistics of 90nm chip manufacture are simple or cheap. It's still pretty high tech stuff, people aren't doing it in their garage. I don't know why automakers didn't engage their partners here to expand manufacturing. I am sure they asked, and the companies that can build 90nm fabs decided not to. Maybe it doesn't make sense after the backlog is cleared, maybe they like the higher prices? And if a car company wanted to start manufacturing chips themselves, they'd have to hire engineers, license patents, work out bugs, etc. and the risk is that the shortage is completely gone after you do all of that. (And, all this during a pandemic. If they wanted to use wood to build the physical building containing the fab, there was a shortage of that. So, a lot of problems to solve, and 10 billion dollars starts looking like a small number.)
