Tesla is highlighting the real-world power of its autonomy software through the eyes of a customer who recently did the unthinkable. David Moss, a Model 3 owner, successfully completed a coast-to-coast trip across the United States last December using Full Self-Driving (Supervised) with absolutely zero interventions.
According to a new customer story shared by Tesla, Moss traveled from the Tesla Diner in Los Angeles all the way to Myrtle Beach, South Carolina. The journey covered 2,732 miles in just 2 days and 20 hours. During that entire window, the car handled every turn, stop sign, and even navigated the Supercharger stops without David having to touch 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
This cross-country sprint was actually part of a much larger mission. David managed to reach a record-breaking streak of 12,961 miles without a single intervention. For nearly eight weeks, he traveled through 30 different states, trusting the car to navigate complex urban environments and long highway stretches alike.
David himself 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 only came to an end due to the weather. While driving through rural Wisconsin in January, David encountered snow-covered roads and freezing temperatures that obscured lane lines. Choosing safety over the streak, he took over manually to navigate the icy conditions. It’s a reminder that while FSD (Supervised) is incredibly capable, extreme edge cases like blizzards still provide a challenge for neural networks.
The Road to Global Autonomy
David’s journey took place on FSD version 14.2, but the software is moving fast. 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 those tricky weather scenarios that David encountered and move Tesla closer to its goal of unsupervised autonomy.
Tesla sharing the success of FSD’s long-distance runs is perfectly timed with the company’s global ambitions. The software is finally set for European approval in the Netherlands next month, which will open the door for a massive expansion across the EU.
What David Moss proved is that the "coast-to-coast" self-driving dream Elon Musk talked about a decade ago isn't just a promise anymore — it's a verified reality and inching closer to an everyday occurrence. As Tesla continues to refine the system, these intervention-free streaks will likely become the standard rather than the exception. We’re moving closer to a world where "driving" across the country simply means picking a destination and enjoying the ride.
