> when they seriously start releasing electric vehicles They've been "serious" for a long time. Chevy has been selling the Volt since 2010. If they were going to muscle out Tesla they would have done it by now. And it's not just about technology. Tesla has the customer reputation that companies like GM will never have again.
GM isn't a threat to tesla unless Cadillac starts selling something to compete with the model S. As a Tesla shareholder what keeps me up at night are Mercedes, BMW, and Lexus.
