Am I correct that the most expensive part of an electric vehicle is the battery? The battery is the main driver behind range/performance. With the gigafactory tooled to produce batteries en mass, wouldn't it allow Tesla to produce batteries cheaper than anyone else? Cheaper batteries make for cheaper cars or better performing cars at the same price point. This would seem to me, a bright future for Tesla ahead if they have a significant production/costing advantage for their EV against other EVs making long positions a good one for Tesla? Also, would Tesla be willing/get interests to do so about selling their batteries to other EV manufacturers? Like a Tesla battery inside a Toyota, GM vehicle etc. Would appreciate any agreements or disagreements with the above.
