> I always like to show these videos to illustrate:

The videos are fun, but of a very limited scope. I would like to see the corresponding videos made by an independent person, or by people who make steel, aluminium and titan frames. People who sell carbon frames at a higher price point have every incentive to bias the results of these experiments in their favor (for example, by intentionally producing less robust aluminium frames for their lower end products).

That seems unlikely as there's plenty of competition amongst bike manufacturers, so deliberately weakening a cheaper model would just lead to a drop in reputation. There's a reason that carbon frames are popular - it can be made extremely strong and still be light.
