Tesla has passed another milestone set by Elon Musk for "safe unsupervised driving." According to the company’s updated safety page, the cumulative mileage of Tesla’s fleet equipped with the “Full Self-Driving (Regulated Version)” function has exceeded 10 billion miles. This means that the company has reached the data threshold that Musk set for "safe unsupervised self-driving" earlier this year.

However, when Tesla owners woke up today, they did not find that the fully autonomous driving (supervised version) function in their car had been upgraded to an "unsupervised" version overnight. At present, FSD is still only an L2 level driving assistance system, which requires the driver to maintain concentration throughout the entire process, monitor the road conditions at any time, and immediately take over the steering wheel when necessary.

In January this year, Musk stated on social platform His statement at the time seemed quite suggestive to the outside world: Once the fleet accumulates this level of data, Tesla will "flip the switch" and allow all users to instantly gain unsupervised autonomous driving capabilities.

But judging from the actual results, such a "second switching" did not happen. If Tesla really opens up unmanned supervision capabilities directly at this point, it will be an extremely risky operation. There are still many questions surrounding whether and to what extent the company is willing to take legal responsibility for the more than one million vehicles equipped with FSD systems.

Under the model of another self-driving company, Waymo, if its driverless vehicles cause an accident, the company will bear liability because Waymo controls both the vehicle and the technology. Tesla, in its user agreement, places most of the responsibility on the car owner by defining FSD as an "L2 regulated system." This also leads to a core question: Once FSD crosses from "regulated" to "unsupervised", how will the responsibilities be divided? When an accident occurs, who should bear the consequences?

At present, Tesla does not seem to have given a clear answer.
