it's great that BMW leaves no stone unturned in engineering their cars
I wish that it was true.
Unfortunately, they don't seem to spend enough time in certain areas. Reliability for example. We still hear about windows regulator failures. If they were obsessed with reliability-by-design like Honda, this problem would be resolved by now. And before you ask, I don't think that is incompatible with driving dynamic.
They also have a tendency to create problems, answering questions nobody asked. Run-flat tires WITH NO SPARE TIRE ROOM (that is the point IMO) is incredible. In order to save maybe 2HP, they have an electric water pump that costs 1500$ to fix instead of 500$.
No surprise that nobody really followed them in this kind of craziness in 7 years.
