Building on his prior 5,008-mile zero-intervention journey in December 2025, Tesla owner David Moss completed a 2,732.4-mile cross-country trip from Los Angeles to a South Carolina beach on January 1, 2026, using Full Self-Driving version 14.2.1.25. This first third-party verified zero-intervention drive spans two time zones over two days and 20 hours, showcasing FSD advancements amid mixed reviews and ongoing challenges.
Tesla owner David Moss marked another milestone for Full Self-Driving (FSD) v14 on January 1, 2026, driving a Model 3 with v14.2.1.25 and AI4 hardware from Los Angeles to a South Carolina beach—a 2,732.4-mile journey completed without any human interventions, as third-party verified. Following his earlier 5,008-mile achievement in December 2025 (mostly highway), this cross-country trip fulfills Elon Musk's vision for unsupervised long-distance travel and has been hailed on social media as passing a 'physical Turing test.'
FSD v14 integrates with Grok AI in vehicles delivered since July 2025, forming a 'dual-brain' system: FSD manages driving, while Grok enables dynamic routing (e.g., avoiding tolls, scenic stops), self-diagnosis, explanatory decisions, and personalized features.
Reviews remain divided. While some praise v14's stability, Electrek's Fred Lambert reported interventions during a 125-mile test, criticizing untimely lane changes and emphasizing that FSD still requires supervision, falling short of promises. User concerns echo this, with one noting supervision feels like 'a chore.' A California judge recently ruled Tesla misled consumers on self-driving claims, amid sluggish 2025 sales despite EV market growth.
These drives advance Musk's 'trinity' of FSD, Grok, and Optimus (shareholder-approved November 2025), with Optimus Gen3 now handling factory tasks using data from millions of Tesla vehicles.
