According to Project_RCC on Twitter, recent discussions highlight that Tesla's Full Self-Driving (FSD) system is restricted by NHTSA regulations from performing rolling stops, even at minimal speeds like 0.5 mph, despite internal Tesla data indicating that fewer than 1% of human drivers come to a complete stop at stop signs (source: Project_RCC via X, Dec 23, 2025). This regulatory barrier significantly impacts the real-world deployment and perceived competitiveness of autonomous vehicle solutions, as compliance requirements can lead to less natural driving behavior, affecting user adoption and business scalability. The situation underscores how regulatory frameworks directly influence AI-driven mobility innovation and present both challenges and opportunities for companies developing autonomous driving technology.
