The thing he doesn't show is just how much weaker CF is in compression than it is in tension. As much emphasis as we place on torsional chassis strength for performance, any amount of crash safety requires compressive strength.
Could it work? Certainly. There are plenty of carbon tub cars out there. However, the first chassis would not be quick, easy, or cheap to design and build correctly.
The reason I'll stick with steel for any safety critical elements is that it's
far more forgiving to the TLAR (That Looks About Right) engineering used for these types of builds.
