Tesla 2026.14.6.10 adds FSD v14.3.4 and a route shortcut

Tesla has started sending out software version 2026.14.6.10 and the build includes Full Self-Driving (Supervised) v14.3.4. The release brings changes across driving behavior, parking logic and the system used to process driving inputs.

A screenshot shared by an owner points to a new button in the trip card that appears to make it easier to add a waypoint to an active route. Tesla has not explained that button in public release notes.

FSD v14.3.4 brings a deeper software update

Tesla’s release notes say v14.3.4 includes a rewritten AI compiler and runtime built on MLIR, along with a new reinforcement learning training stage. The company says the update cuts reaction time by 20% and speeds up model iteration.

The update also brings a new vision encoder that Tesla says improves response in rare and low-visibility scenes. And the release notes say the system handles emergency vehicles, unusual objects and parking maneuvers with more precision.

Parking gets more attention

Tesla says the car now predicts parking spots on the map when a driver reaches a destination. The release notes say the system can present parking options at the end of a trip, which may reduce some of the guesswork once a drive is nearly over.

That change sits alongside other parking updates in the same build, including better spot selection and improved parking behavior in tight spaces. And for drivers who use navigation often, that part may be the most practical change in the update.

The new waypoint button (undocumented)

The image shared with this update shows a new icon next to the trip controls, placed near the End Trip button. Tesla has not documented the feature, so users may see different behavior depending on the car and software state. Still, the button fits a clear use case since many Tesla drivers add stops during a trip and want a faster path to do it.

This is a small change on the surface, yet it can save time inside the navigation screen. A quicker waypoint action is useful when plans change on the road and the driver needs to add a stop without working through extra menus.

The rest of the update is more technical, but it may have a larger effect over time. Tesla says the driving stack in this build is faster, better trained and more accurate in edge cases, which is the kind of update owners tend to feel over many drives rather than in one quick test.
