Tesla began rolling out software version 2026.20.6.6, which carries Full Self-Driving (Supervised) version 14.3.5, on July 13, 2026. The update reached non-employee vehicles first and, as of this writing, is limited to cars with Tesla’s Hardware 4 (HW4) computer, according to TeslaNorth. It follows 2026.20.6.1, an earlier build on the same software branch that Tesla released July 2 and that GetTesla covered at the time.
The most visible change for owners is an expanded Camera Preview. Tesla first added the ability to view a car’s external camera feeds from the touchscreen in 2023, but that view previously only worked while the car was parked. With this update, drivers can open Camera Preview — under Controls, then Service, then Camera Preview — while the car is in motion, including the interior cabin camera, according to Tesla Oracle‘s review of the release notes. Tapping an individual camera in the on-screen grid enlarges that feed; tapping the grid icon again returns to the full view.
Tesla also raised the top speed of Actually Smart Summon, the feature that lets a car pull itself out of a parking spot and drive to the owner in a lot or driveway, to 8 mph (13 km/h). Tesla’s release notes describe the underlying driving model as now “unified” across Actually Smart Summon, FSD (Supervised), and the company’s robotaxi service — meaning the three now share the same core software rather than separate versions — according to the official notes mirrored by Not a Tesla App.
On the driving side, Tesla says this build improves how FSD handles traffic lights at complex intersections, including ones with multiple signal heads, curved approaches, or a yellow light, and increases decisiveness when selecting and pulling into a parking spot. When a car nears a parking destination, the map now shows nearby parking options marked with a “P” icon. The Tesla mobile app also gained a running count of miles driven in FSD without the driver needing to intervene, along with a driver’s longest such streak.
Some of the language in this build’s release notes — an upgraded reinforcement-learning stage for training the FSD neural network, an improved vision system for reading traffic signs and handling low-visibility conditions, and a rewritten AI compiler using a framework called MLIR (Multi-Level Intermediate Representation) that Tesla says makes the car’s reaction time about 20% faster — is carried over from FSD v14.3, the version Tesla introduced in April 2026, according to Electrek‘s reporting at the time. Tesla repeats this description across every build on the v14.3 branch, so it describes the architecture v14.3.5 continues to run on rather than a change unique to this week’s update.
For owners, none of this requires action. Like all Tesla software, 2026.20.6.6 downloads over Wi-Fi and installs automatically once the car is parked and idle; owners can check whether it has arrived under Controls, then Software, on the touchscreen. Because the update is currently limited to Hardware 4 vehicles, cars with Tesla’s older Hardware 3 computer will not receive it.
