Tesla says FSD (Supervised) has logged 10 billion miles, but it remains a Level 2 system
Tesla's FSD (Supervised) system has logged 10 billion miles, meeting a key internal metric, but remains a Level 2 system for public use.

Tesla says vehicles using its Full Self-Driving (Supervised) feature have accumulated more than 10 billion miles as of May 4, 2026, according to an update to the company’s safety page.
The milestone lines up with a rough benchmark CEO Elon Musk has previously cited for reaching “safe unsupervised” driving. However, Tesla has not shisourcesed its customer-facing system to an unsupervised mode.
Tesla continues to describe FSD (Supervised) as a Level 2 advanced driver-assistance system, meaning a human driver must remain attentive and be ready to take control at all times.
That classification also affects crash responsibility. In a supervised Level 2 model, responsibility typically remains with the driver rather than the technology provider, unlike some autonomous fleet operations where the operator assumes responsibility.
Internal robotaxi deployment remains limited
Tesla’s internal robotaxi program is expanding its use of unsupervised vehicles, according to the report.
It says Dallas is operating five unsupervised robotaxis, Houston has six, and Austin includes 22 unsupervised vehicles alongside 29 supervised units.
The split between supervised and unsupervised operation suggests a phased approach to autonomy, while questions around liability and any broader public release remain unresolved.
