Tesla was once the red-hot center of car innovation, but now it feels at risk of sinking into irrelevance as just another auto maker. Its coming Robotaxi Day may be Elon Musk’s last chance to convince investors that Tesla still has it.

Tesla boss Elon Musk is no stranger to litigation, having fought off legal challenges against his massive salary, claims of a conflict of interest between his companies and even accusations of insider trading.
