Elon repeatedly tries to misdirect from the issue at hand. Teslas do not catch fire more often than the average U.S. car. But that is not in question. The question is, "after a collision, what happens?" And so far, the answer is, "the Model S has a 25x increased chance of catching fire." That is the focus of the investigation. Fires post-collision are a bad thing, even if the never reach the occupant: they can ignite other cars gas tanks (or other objects), and impede rescue work.
