Tesla Model 3 Full Self Driving Supervised System Completes Transcontinental Journey from California to South Carolina Covering 4300 Kilometers
The Tesla Model 3 successfully completed a transcontinental trip using its Full Self Driving technology which operates under human supervision. On March 27 2026 reports surfaced detailing a significant achievement for Tesla and its driver assistance technology. David Moss who drives a Tesla Model 3 in America completed a full transcontinental drive from coast to coast through the Full Self Driving Supervised system. The trip covered a total distance of 4300 kilometers spanning the vast geography between California and South Carolina.
The expedition across the country started from the West Coast and reached its end point at the Atlantic Ocean. David Moss recorded that the entire journey required two days and 20 hours to complete. The distance equals the distance between Moscow and Krasnoyarsk based on a standard map. The vehicle drove for 4300 kilometers while the driver had to stay in the seat to oversee its operation.
The technology used during the trip is classified as FSD Supervised. The system requires human drivers to stay alert because it will automatically control steering and acceleration. Tesla does not currently categorize this as a fully autonomous system and the driver remains legally responsible for the vehicle during its operation. Moss acted as a safety observer throughout the duration of the trip to ensure the car navigated highway transitions and traffic correctly.
This specific journey across America was part of a larger personal testing project conducted by Moss. He has now accumulated a total of 19300 kilometers using the Supervised FSD software across various road conditions and environments. The documentation of the trip included short video reports and driver observations to demonstrate the software capabilities in 2026. The findings show that the system can handle long distance travel while the driver needs to provide only basic physical support as long as they keep monitoring the situation.
The 4300 kilometer trip demonstrates both safety issues and effectiveness problems with automated driving technology. The successful arrival in South Carolina marks another milestone in the ongoing collection of real world data for Tesla and the broader automotive industry.
