If true, the move would offer a major boost to Musk's EV firm. Tesla is staking its future on the idea of rolling out mass fleets of autonomous vehicles, known as "robotaxi" services. At the firm's "We Robot" event in October, Musk unveiled the firm's Cybercab self-driving concept car.
Tesla has yet to deliver on Musk's promise of offering truly autonomous vehicles. Tesla's Autopilot and paid "Full Self-Driving" services still require a human behind the wheel to supervise the system's actions and take over if needed.
