Tesla has serious quality control issues. They have serious design issues like being deliberately obtuse in the name of “innovation”. They haven’t made any significant improvements to any of their cars since the launch.
Most importantly, they have serious leadership issues. Particularly, a long history of deception and broken promises.
Musk was in the right place at the right time to launch Tesla. He’s got a pretty good corner on the battery market, and hopefully he doesn’t abuse that.
