A fatal accident in Florida triggers a protracted lawsuit to hold Tesla accountable. And it's not the only incident. Shocking footage from dashcams and security cameras shows the ruthlessness of Tesla cars suddenly braking or accelerating—and the crashes that follow. Then, an employee leaks thousands of documents containing complaints from users.
