Also i would assume that the non-Tesla offerings will be cheaper. What i saw about the automobile industry ist that they are very good in building factories/supply chain's where they can produce as cheap as possible. The setup of such a supply chain takes years but when it's there i assume that the prices will be lower than Tesla's. (Also so far i know Tesla need's still a relativ big amout of work hours per car, 60h compare to 30h industry standard)
