You're putting words in my mouth: I've never said any such thing. I've spoken exclusively about Toyota and their software development practices, which is what this thread is about. I've literally not mentioned any other manufacturer at any point, let alone expressed the opinion that any of them "are any better" - although now that you mention it I'd frankly be very hard pressed to see how any of them could possibly be much worse than what is described here. That'd be difficult to do while still having your code even compile.

I've see a lot of code over the years, written in numerous languages and running on a very wide variety of hardware. Some of it was... Terrible. I've yet to see anything anywhere that had a global shared state space of 10000 distinct variables. That's beyond insanity.
