Tesla is a tech company that happens to make cars, they are valued as such because they have separate individual companies within the company itself. 1) They own Perbix which manufactures robotic for factories, 2) Mobile eye which is a develop company for the other auto industry brands. 3) Tesla power storage division 4) Tesla Gigafactory manufacturer for batteries for anything out there that uses batteries not just for their own cars. I know I'm forgetting more but these was on top of my head, each in their own are worth lots of coin and make additional value for Tesla. Google, and Apple are two other tech companies in talks in making their own cars in the future. Electric cars are here to stay and Tesla was the first in a long time to disrupt the auto industry, also this might be hard to believe here on this forum but there is millions maybe billions of people that can care less what a car sounds like.
