Tesla Full Self-Driving Fleet Hits 10 Billion Miles

Tesla's fleet of vehicles using the Full Self-Driving (Supervised) system has driven over 10 billion miles, crossing a threshold that CEO Elon Musk identified in January 2026 as necessary for safe unsupervised self-driving. In a post on X that month, Musk stated that roughly 10 billion miles of training data is needed to achieve safe unsupervised self-driving.

The milestone, announced via Tesla's updated safety page, comes as the company ramps up its robotaxi operations in Texas.

Tesla launched its robotaxi service in Austin, where it now operates 29 supervised vehicles with employees in the front passenger seat and 22 unsupervised ones, according to Robotaxi Tracker. The company also started services in Dallas with two vehicles, expanding to five unsupervised robotaxis, and in Houston with a pair, now totaling six unsupervised vehicles.

During an earnings call last month, Musk stated that unsupervised driving was coming when it is legal to do so.

He predicted that unsupervised Full Self-Driving in customer cars would arrive in the fourth quarter of 2026. Tesla maintains on its website that Full Self-Driving (Supervised) requires active driver supervision and does not make the vehicle autonomous. The system is classified as a Level 2 feature, necessitating a fully attentive human driver.

Separately, a federal jury in Florida found Tesla partly liable for a deadly 2019 crash involving its Autopilot software and ordered the company to pay $243 million to the victims' families.

Tesla appealed the ruling, but a judge rejected the appeal.
