The small cells means they have to have many, many. Every one is a potential hazzard point. I guess that is why I never bought Tesla stock. Instead I picked a battery company that had a better design. Now it appears to be one of the best battery cells on the market. Electrovaya is making other battery manufacturers improve their designs. That is good for the industry. When will Tesla get a descent battery cell??
