You're kidding if you think the premium brands you list don't have massive dependence on software systems. The basic physics is, as you say, better because they've kept mass distribution in line with how it was.

And how about the additional failure mode for say BMW. It's modern controllers have all the software for all the features in, just disabled unless you pay more. So a theoretic sophisticated attack could throw all sorts of crap into operation.
