I don't think any of these videos are embarrassing. Silly, yes, but not embarrassing. They are contrived situations. How often do you have 100% traction on one axle, and zero on the other axle? As long as there is a mechanical differential involved, as in the Audi, you need something to trigger the electrical lock up so that you get drive on both axles. If that was a real hill, both vehicles would have driven up it fine.

Now if it was a comparison tire test, that would matter. But different AWD systems have so little to choose between them, that these adds just make the producers look silly, like political attack adds do.
