But other than that I mostly agree, I don't think that the over-engineering is greed driven - but the EU Manufacturers (but honestly, even other ones) have a really hard time with anything software based. Be it in car or outside of it. But BMW is far from the worst on that front.
P.S: VW ODIS original diagnostic is based on Eclipse :D
That kind of thinking along with some calcification of organizational structures in/around R&D teams seems to be the cause for the rather dysfunctional software development at the German car companies. Software dev doesn't thrive in this environment.
Volkswagen probably had the right idea on paper when they created Cariad as a subsidiary software development company to isolate the devs, but then they ruined it by importing their own culture into it again.
