I'm not sure why this is surprising? There's nothing much unique about Tesla that would preclude other, more established car companies from competing in the EV space. It was only a matter of time. This is why I've never understood Tesla's high stock prices. Sure, Tesla's got big battery factories, but those are being set up by other manufacturers as well. There's not a lot of secret sauce here.
