Tesla’s latest Full Self-Driving update marks a considerable milestone for the company’s autonomous driving technology. Version 14 represents the first major FSD update in roughly a year. Tesla began rolling it out in October 2025 after focusing development efforts on its internal robotaxi fleet in Austin.
The new version promises improved performance compared to its predecessor. Version 13 achieved critical disengagements—moments when drivers must take control—roughly every 400 miles. Version 14 is expected to extend this to between 800 and 1,200 miles. However, early reports suggest the actual improvements haven’t fully matched these expectations. The system still requires frequent driver oversight despite the advancements. Tesla’s training on billions of miles of real-world driving data enables these incremental safety improvements.
One notable improvement involves how the system handles uncertainty. The new update includes better decision-making processes that reduce problematic hallucinations—instances where the car incorrectly perceives its environment. This means fewer unnecessary alerts demanding immediate driver intervention. This addresses a key concern since 90% of crashes involve human error, such as distraction or poor lane discipline.
FSD v14 can complete numerous driving tasks. The system handles route guidance, steering, and lane changes while supervised. It maneuvers through parking lots and tight spaces to reach owners when activated through Tesla’s app. The software independently selects routing forks, makes left and right turns, checks blind spots using 360-degree cameras, and parks autonomously while avoiding obstacles.
Tesla’s safety data shows Autopilot and FSD technology considerably outperform national averages. Vehicles using these systems crash once every 6.69 million miles, compared to one crash per 963,000 miles for non-autonomous vehicles. The national average sits at approximately one crash per 702,000 miles.
The feature currently operates in the United States, Canada, China, Mexico, Puerto Rico, Australia, and New Zealand. Availability varies by region based on local regulations. Drivers must continuously supervise the system during operation. FSD v14 doesn’t constitute fully autonomous driving. It remains a supervised system requiring active driver attention.
Elon Musk previously stated a goal for supervised FSD to become fully unsupervised by year-end. However, regulatory approval timelines remain uncertain. The rollout to customers has been selective, with Tesla gradually expanding access as development continues.
