And that's not all. I used to work with a guy who spent a large portion of his career at a famous car manufacturer. I can't say which one cause their operation and output is rather small(niche, hyper-wealthy customers that take their international passport when they go for a drink across the street, "just in case"). From what he told me, their cars have 11 individual computers with full operating systems on them for various reasons. While compute has become more expensive over the last few years, courtesy of slop, small, embedded ARM devices are still inexpensive and incredibly powerful. I also spent a short time in the automotive industry(where I met the guy I mentioned) and modern cars are an absolute integration hell and even their engineering teams can't say fully what's in them in terms of hardware and it's magnitudes worse with software.
