Tesla software update 2026.20.10 was listed on July 28, 2026, adding another build to the 2026.20 family. This update covers supervised driving, vehicle convenience and trip planning. Its 10 documented entries explain changes to the ownership experience, from the features used inside the cabin to the software operating behind them. Availability depends on the vehicle and the requirements of each entry.
FSD (Supervised) v14.3.5 Down Under is listed for Model S, Model 3, Model X and Model Y. Availability follows the requirements of each entry; the update number alone does not identify which driving branch a vehicle receives.
FSD (Supervised) v14.3.5 Down Under improves learning and visual understanding for unusual or low-visibility situations. Changes address parking decisions, lane positioning and responses to emergency vehicles, school buses, animals and complex traffic lights. The revised AI runtime is described as delivering 20% faster reactions. These refinements concern how the driving system interprets the road and chooses maneuvers while the driver continues to supervise. Intervention feedback and driving-distance statistics also provide more information about the journey. Arrival Options saves parking or drop-off preferences separately for each destination. Speed Profiles uses driver preferences, road limits and traffic to select driving pace. SLOTH uses lower speeds and more conservative lane choices than CHILL. UI Improvements puts driving preferences directly in the center display visualization. Driving statistics and touchscreen activation are also documented. Arrival preferences can be adjusted there as well.
Brake Confirm makes the activation pedal-confirmation step configurable and defaults it off in this entry.
Second Row Child Safety Seats directs Model Y L owners to additional installation guidance.
Navigation Lane Guidance needs Online Routing and maps 2026.20 or later. Send Destination to Car shares locations through app 4.57.0 or supported Korean mapping apps. Weather Maps displays rain, snow and the previous hour of conditions with Premium Connectivity. Points of Interest makes map landmarks selectable for exploration or navigation.
Driving assistance continues to require continuous driver supervision. The documented capabilities can include features carried forward within the same software branch.
