Your practical examle (crosswiring):
Let's assume it would have happened on a 777. After take-off, in the very first turn the crosswiring would have produced such a awkward feeling and looking situation (Captains yoke turns one way, Copilots the other) that any crew would have picked it up. On a Airbus, with dead sticks, only if the Captain would have done this first turn manually. Apparently this was not the case and they only picked it up at landing.
I will stop by now, not wanting a A vs. B match, but this example very nicely sustains my argument.
Off to a nice flight with my Airbus!
