Tesla is ready to unveil its new line of self-driving cars in Austin, Texas, challenging Waymo’s dominance in the robotaxi industry.

Tesla's promise of launching fully self-driving cars is a decade old, but so far its vehicles have always required constant driver supervision. But CEO Elon Musk announced on Wednesday that the automaker's first true "unsupervised" self-driving system will be launched in June, starting in Austin as a paid ride-hailing service.
