Tesla reaches 10 billion FSD miles — is there’s a magical milestone for autonomy

Tesla’s Full Self-Driving (Supervised) fleet has crossed the 10 billion mile mark, according to the automaker’s updated safety page. It’s the threshold that CEO Elon Musk himself set earlier this year as the data milestone needed for “safe unsupervised” driving.

The achievement represents a massive acceleration in data collection — the fleet was logging roughly 29 million miles per day by late April, up from 14 million miles per day at the start of the year. But hitting a round number doesn’t mean Tesla is about to flip a switch on Level 4 autonomy.

A goalpost Musk set himself

In January 2026, after Tesla failed to deliver unsupervised FSD by the end of 2025 as promised, Musk stated that the company needed approximately 10 billion miles of real-world driving data to achieve safe unsupervised self-driving. That figure itself was a moved goalpost — he had previously indicated 6 billion miles would be sufficient.

Tesla’s safety page now reports one major collision per 5.3 million miles under FSD (Supervised), compared to one per 660,000 miles for the average US driver. The company frames this as evidence the system is dramatically safer than human driving.
