What does Tesla FSD mean?

SAE Level 2 means the system can handle both steering and speed simultaneously, but the human driver must remain engaged and monitor the environment at all times. This is fundamentally different from Level 4 (Waymo robotaxi, no driver needed in a geofenced area) or Level 5 (full autonomy everywhere). Tesla's marketing uses the term Full Self-Driving, which has led to public confusion about the system's actual capability level.

Tesla FSD (Supervised) is a consumer driver-assist feature on privately owned Teslas. The driver is always present and responsible. Tesla Robotaxi is a commercial ride-hailing service operating in unsupervised mode within a geofenced area (Austin lead, June 2025). In Robotaxi mode, there is no driver to hold responsible; Tesla as the operator bears liability. The two systems share underlying FSD software but are different products with different legal and safety frameworks.

Tesla Full Self-Driving (Supervised), or FSD, is Tesla's advanced driver-assistance system. It is classified as SAE Level 2: the system can steer, accelerate, and brake in both highway and urban environments, but the licensed driver must monitor the road and be ready to take over at all times. The word Supervised in the name reflects this: it is not unsupervised autonomy.

Tesla Autopilot is the standard driver-assist system bundled on all Tesla vehicles since 2015. It provides adaptive cruise control and lane keeping on highways. FSD (Supervised) is the paid upgrade that adds: navigation on city streets, traffic-light and stop-sign recognition, automatic lane changes, and parking assistance. Both are SAE Level 2. The driver is responsible for both.
