Tesla is showcasing the real-world capability of its autonomy software through a customer feat: David Moss, a Model 3 owner, completed a coast-to-coast U.S. drive last December using Full Self-Driving (Supervised) with zero interventions.
In a customer story shared by Tesla, Moss drove from the Tesla Diner in Los Angeles to Myrtle Beach, South Carolina. The trip spanned 2,732 miles in just 2 days and 20 hours. Throughout the journey, the car managed every turn, obeyed stop signs, and even handled Supercharger stops without Moss touching the steering wheel or pedals.
Tesla has released a new video with @DavidMoss, highlighting his recent cross-country trip on FSD (Supervised) with zero disengagements.

Crossing the 10,000-Mile Threshold
The cross-country sprint was part of a larger effort. Moss achieved a record-breaking streak of 12,961 miles without a single intervention. Over nearly eight weeks, he traveled through 30 states, relying on the car across complex urban streets and long highway stretches.
Moss shared his excitement on X after reaching the Atlantic coast, stating, "This was accomplished with Tesla FSD V14.2 with absolutely 0 disengagements of any kind even for all parking including at Tesla Superchargers."
The streak ended due to weather. While driving through rural Wisconsin in January, Moss encountered snow-covered roads and freezing temperatures that obscured lane lines. Prioritizing safety, he took over manually to navigate the icy conditions. It underscores that while FSD (Supervised) is capable, extreme edge cases like blizzards remain challenging for neural networks.
The Road to Global Autonomy
Moss’s journey used FSD version 14.2, and Elon Musk recently confirmed that version 14.3 is already in testing and should see a wide release shortly. Each update aims to further close the gap on the tricky weather scenarios Moss encountered and move Tesla closer to its goal of unsupervised autonomy.
Sharing the success of long-distance runs aligns with the company’s broader ambitions. The software is set for European approval in the Netherlands next month, which could open the door to a wider rollout across the EU.
Moss’s accomplishment shows that the "coast-to-coast" self-driving milestone Elon Musk referenced a decade ago is now a demonstrated reality and edging toward everyday occurrence. As Tesla refines the system, intervention-free streaks are likely to become the norm, bringing a future where "driving" across the country can mean choosing a destination and enjoying the ride.
