Tesla Passed 10 Billion FSD Miles. That Is Not a Safety Verdict

Correction: The original version of this article said Tesla had crossed 10 billion Full Self-Driving miles “this week” around April 15, 2026. The milestone was reached in early May. It also compared 10 billion miles with 600,000 driving lifetimes, a calculation that was wrong and has been removed.
Tesla's safety page showed more than 10 billion cumulative miles driven with Full Self-Driving (Supervised) in early May 2026. Barron's reported 10.05 billion miles on May 5. The number reflects extensive use of the system, but mileage alone does not establish that it is safer than human driving.
What the milestone tells us
Ten billion miles gives Tesla a large pool of real-world driving data. It can help the company find unusual road situations, train newer software and measure how often certain events occur. It also shows that many owners are willing to use the system regularly.
But cumulative mileage is an exposure figure, not a controlled safety comparison. To judge safety, researchers need comparable definitions of a crash, similar roads and weather, vehicle age, driver behaviour, geographic coverage and clear reporting of when the software was active.
Why Tesla's safety comparisons need care
Tesla calls the product Full Self-Driving (Supervised). The driver must remain attentive and ready to take control. It is not the same operating model as a driverless service that runs without a person behind the wheel.
A later Reuters examination of Tesla's safety methodology found that some company comparisons used different crash definitions for Tesla vehicles and the broader U.S. fleet. Researchers interviewed by Reuters said those mismatched definitions could make the safety advantage appear larger than a like-for-like comparison would support.
What Canadian drivers should know
The feature's name does not change the driver's legal responsibility. Canadian owners need to follow the instructions shown in the vehicle, keep their attention on the road and understand that availability and capability can differ by software version and location.
The 10-billion-mile milestone is real and noteworthy. The original publication date and “600,000 lifetimes” comparison were not. This revision corrects those errors and keeps the safety conclusion narrow: the mileage total is evidence of scale, not proof of autonomy or a complete safety verdict.
