A good discussion is contained in the old Herb Adams book.

The point is not saying the MC chassis is JUST like a BD, but the principle is the same. The BD has quite a bit shorter of a WB, plus you have a plastic body bolted on to help to help. These examples also have no G-Force loads which will enhance any twist further.

I don't disagree with the premise of your argument but your example was piss poor. Your example couldn't possibly be any more irrelevant.
