A Tesla vehicle equipped with Full Self-Driving (Supervised) version 14 has completed a 5,008-mile journey entirely autonomously, with the human occupant not touching the pedals or steering wheel once. This feat, reported on social media, equates to the distance from Miami, Florida, to Anchorage, Alaska. The drive consisted of 10% city streets and 90% highway, with no interventions required.
On December 18, 2025, Tesla enthusiast Sawyer Merritt shared impressive statistics from a real-world test of the company's Full Self-Driving (FSD) Supervised version 14. The test was conducted in a 2025 Model 3 Long Range Rear-Wheel Drive vehicle owned by David Moss.
The autonomous system covered 5,008 miles, while the human in the car drove zero miles. Merritt described the achievement as 'the equivalent of driving from Miami, Florida to Anchorage, Alaska without ever touching the pedals or the steering wheel once,' calling it 'incredible.' The route breakdown showed 10% city driving and 90% highway, and notably, there was not a single intervention by the driver throughout the entire distance.
This demonstration highlights the advancing capabilities of Tesla's FSD software under supervised conditions, where a human remains present but does not actively control the vehicle. Such tests provide valuable data for improving autonomous driving technology, though they occur in a controlled, supervised environment rather than fully unsupervised operation. The results underscore Tesla's ongoing efforts to refine its AI-driven features for safer and more reliable long-distance travel.
No further details on the exact route or environmental conditions were provided in the report.
