According to Sawyer Merritt, more Tesla owners have purchased or subscribed to Tesla’s Full Self-Driving (FSD) system in Q4 2025 than in any previous quarter over the past 5.5 years, indicating a significant uptick in consumer adoption. This spike is attributed to the positive impact of FSD (Supervised) V14, which has improved user experience and trust in Tesla's AI-powered autonomous driving technology. Merritt notes that ongoing free trials are further boosting engagement, and anticipates an additional surge in sales and subscriptions when the free trial period ends and FSD V14.3 is released next month. This trend highlights a growing market opportunity for AI-driven mobility solutions and positions Tesla’s FSD as a leading example of scalable AI application in the automotive industry (Source: @SawyerMerritt, Dec 5, 2025).
