No current Waymo or Tesla full self-driving car is fully autonomous.

“The claim is accurate. "Fully autonomous" corresponds to Level 5 on the SAE scale, where a vehicle can operate anywhere under any conditions without human oversight. As of March 2026, no company has achieved this. Waymo's driverless service operates at Level 4, meaning it is autonomous but restricted to specific geographic areas (geofencing). Tesla's system, despite being named "Full Self-Driving (Supervised)," is classified as a Level 2 driver-assistance system, which requires the driver to remain fully attentive and ready to intervene at all times. Context: The distinction between different levels of automation is crucial. Waymo operates a Level 4 autonomous ride-hailing service in several cities, which does not require a human driver within its operational domain. Tesla's FSD is a Level 2 system available to consumers that assists with driving but legally requires constant human supervision.”
