In a breakthrough in the history of autonomous driving, Tesla has managed to drive across the United States, uninterrupted, coast-to-coast on Full Self-Driving (FSD) Supervised, without any human intervention whatsoever. Completed by the Tesla owner, Davis Moss, in late December 2025, it is the first known example of an autonomous system working with a full cross-country route from start to finish in real-world conditions.
The motivation immediately ignited celebrations in the Tesla community on X, and it was also celebrated by senior Tesla executives. To a firm that long boasts of complete autonomous capability, the accomplishment is symbolic and technical.
A True Coast-to-Coast Autonomous Journey
The historic work was done using a stealth gray Tesla Model 3 with AI4 hardware and FSD Supervised v14.2.1.25. As per community trackers and FSD database information, the last time Moss drove 10,638.8 miles, FSD was engaged 100% of the time.
The coast-to-coast trip was only 2,732.4 miles and took only 2 days and 20 hours to accomplish. It started at the Tesla Diner in Los Angeles, California, and ended at Myrtle Beach, South Carolina, over highways, city streets, charging stops, and parking maneuvers along the route.
Moss posted on X to highlight the importance of the run: the drive must have zero disengagements, regardless of whether it is in parking or at Tesla Superchargers. He subsequently explained that the trip had no near misses to show that the system was consistent and reliable throughout the cross-country trip.
I am proud to announce that I have successfully completed the world’s first USA coast to coast fully autonomous drive!
I left the Tesla Diner in Los Angeles 2 days & 20 hours ago, and now have ended in Myrtle Beach, SC (2,732.4 miles)

A Long-Standing Goal Finally Realized
The significance of the success is much bigger than the one road trip. An autonomous coast-to-coast drive has long been declared by Tesla executives, when the Tesla Autopilot 2.0 was revealed. Former Tesla CEO, Elon Musk, forecasted at the time that by the end of 2017, such a drive would be able to be completed.
The original schedule was very ambitious, yet the successful run of Moss proves that the original vision was not that unrealistic; it was just too early. Almost a decade later, with the developments of neural networks, hardware, and training in the real-world, that goal has finally become realizable.
Even Musk admitted that the milestone on X was a milestone that many consider an iconic point in the Tesla independence path.
What This Means for Autonomous Driving
Although still considered a supervised system, where a human driver must be alert, the coast-to-coast successful drive is a gigantic top of autonomous real-life advancement. It demonstrates that the vision-only system of Tesla, driven by the large-scale neural networks and fleet data, can be able to cope with long and complicated driving situations without human intervention.
To the critics, the success is yet to be self-driving that is approved by a regulator. As proponents might see it, though, it is strong proof that Tesla is more than ever on the brink of achieving its decades-old autonomy goals. With FSD continuing to develop, the drive across the country may be considered the time when the technologies of autonomous driving ceased being a promise and became a proven fact.
