Tesla's Autopilot and Full Self-Driving (FSD) are Level 2 driver-assistance systems, meaning they require continuous driver supervision despite the "Full Self-Driving" branding. Standard on all Teslas since April 2019, the system provides autosteer and traffic-aware cruise control, while the optional FSD (Supervised) package adds semi-autonomous navigation, self-parking, and summoning. In a notable milestone, the NHTSA announced in May 2026 that recent Model Ys were the first to pass its new advanced driver-assistance benchmark. However, CEO Elon Musk has predicted full Level 5 autonomy since 2013, a goal still unmet as of July 2026, leading to criticism that the branding misleads consumers. The technology evolved from Mobileye-based hardware in 2014 to Tesla's own suite in 2016, with the FSD upgrade briefly removed in 2018 due to confusion. While Tesla claims safety benefits, the systems have faced regulatory scrutiny and media attention over collisions and fatalities.
