π UPDATE β June 17, 2026
Early real-world testing of FSD v14.3.4 is in. Prominent Tesla tester @JoeTegtmeyer reported notable gains in ride smoothness and environmental perception, saying the system moves through complex situations "with confidence." However, he flagged a persistent weakness: speed limit detection remains unreliable across a variety of road types, meaning the car still struggles to select an appropriate driving speed in some scenarios. This lines up with a known pain point from earlier FSD versions and suggests Tesla has not yet fully resolved it in this build.
π UPDATE β June 16, 2026
Real-world footage of FSD (Supervised) v14.3.4 is now circulating, showing the system completing a full drive from parking spot to parking spot on a foggy night β one of the more challenging conditions for camera-based autonomy. Whole Mars Catalog shared the run on X, with both a YouTube upload and raw 1x speed footage available. The clip offers an early look at how v14.3.4 handles low-visibility environments before wider rollout. Full YouTube video and raw footage links are in the tweet below.

π UPDATE β June 16, 2026
Tesla has kicked off a third rollout wave of FSD V14.3.4 via software version 2026.14.6.11, pushing the update to approximately 4,400 additional eligible AI4 vehicles as of late June 15. Notably, this wave introduces Summon support for Cybertruck owners β a feature not previously confirmed for this build. Teslascope fleet data confirmed the new wave within minutes of it going live.
π UPDATE β June 15, 2026
Tesla has begun pushing software update 2026.14.6.11 β the second batch rollout β to approximately 2,420 additional vehicles in just the last five minutes, according to Teslascope fleet data. This build bundles FSD (Supervised) v14.3.4 for eligible AI4 vehicles. Notably, there are no new release notes compared to the previous 2026.14.6.10, confirming this is a bug-fix update rather than a feature drop. The headline feature from 2026.14.6.10 β Actually Smart Summon (ASS) β remains the last major addition to the changelog.
π UPDATE β June 14, 2026
Tesla FSD v14.3.4 includes a newly spotted UI feature that celebrates streak milestones for drivers who consistently use FSD. When you hit a streak milestone, the car's display triggers a visual celebration β a gamification element designed to reward and encourage ongoing FSD engagement. This feature was not mentioned in any official Tesla release notes and appears to be an undocumented addition. π
The milestone UI was first shared publicly by @SawyerMerritt on X, showing the on-screen animation that plays when a streak is reached.

π UPDATE β June 13, 2026
FSD v14.3.4 includes new on-screen status messages that hint strongly at future robotaxi functionality. Owners are reporting strings such as "Vehicle will pull over near destination," "Approaching destination. Will pull over near destination," and "Driving to [location]" β the kind of passenger-facing communication a driverless robotaxi service would require. Tesla watcher @SawyerMerritt flagged the new messages on X, noting they represent a meaningful UX shift toward autonomous ride-hail readiness. These additions were not part of Tesla's official release notes for this version.

π UPDATE β June 13, 2026
Early real-world impressions of FSD v14.3.4 are coming in, and they're striking. Prominent Tesla commentator @wholemars describes the build as "beyond smooth," calling it "powerful, precise, and assertive" β more akin to "technology out of Tron than a human driver." The standout moment? Running Mad Max mode on Mulholland Drive during a dark, foggy night, which he called "just unreal." This is one of the first detailed qualitative accounts of v14.3.4 in challenging low-visibility, winding-road conditions, suggesting the update may bring meaningful improvements to confidence and smoothness in difficult environments.
π UPDATE β June 12, 2026
Real-world testing of FSD v14.3.4 is already surfacing impressive urban driving improvements. Prominent Tesla observer @wholemars reported that v14.3.4 successfully executed a U-turn in San Francisco in order to pull over on the correct side of the road closest to the destination β a nuanced maneuver that previous FSD versions often fumbled in dense city environments. The clip highlights meaningful progress in FSD's ability to plan multi-step urban maneuvers rather than simply stopping at the nearest curb.
"Tesla Self-Driving 14.3.4 just made a U-turn to pull over on the correct side of the road where the destination is. In San Francisco. Very cool"

π UPDATE β June 12, 2026
Tesla FSD (Supervised) v14.3.4 adds a fun new visual reward: celebratory confetti screens now appear when you hit an FSD streak milestone. The feature builds directly on the gamified FSD streaks system that first debuted in v14.2.2.5, deepening Tesla's push to make autonomous driving feel more engaging and rewarding for drivers who maintain clean, intervention-free runs.
@TeslaNewswire Β· June 12, 2026
"Tesla FSD (Supervised) v14.3.4 introduces celebratory confetti screens when you reach an FSD streak milestone! It further enhances the gamified experience that debuted with FSD streaks in v14.2.2.5."
π UPDATE β June 12, 2026
Tesla FSD (Supervised) v14.3.4 is now officially rolling out, bundled with the 2026.14.6.10 software update. Cybertruck owners are getting a notable addition: Actually Smart Summon (ASS) lands on the Cybertruck for the first time with this release. The update also brings UI refinements to the self-driving experience β parking options now appear directly on the map as you approach your destination, and a new on-screen message tells you where FSD plans to park before it does so.
π UPDATE β June 11, 2026
Tesla FSD (Supervised) v14.3.4 has moved beyond detection β it is now officially rolling out to owners. Elon Musk personally confirmed the deployment in two separate posts on X, encouraging owners to "try it out." Prominent Tesla tracker @wholemars also confirmed the rollout is live.
Check your Tesla app now β go to Software β Check for Updates to see if v14.3.4 is available for your vehicle.
Tesla didn't mention this in their release notes, but we found it: Teslascope has detected a new FSD (Supervised) version β v14.3.4 β appearing in the wild as of June 11, 2026. There are no official release notes from Tesla yet, which means this is an undocumented iteration quietly pushed to at least some vehicles. Here's what the detection tells us and what to expect based on the v14.3 series trajectory.
What Was Detected
Teslascope β the automated Tesla software tracker β flagged two new feature strings simultaneously: FSD (Supervised) v14.3.4 and a companion Full Self-Driving (Supervised) feature entry. These detections typically indicate that a build has been pushed to at least one vehicle in the tracking network, even if it hasn't reached most owners yet.
Tesla has not published a changelog for v14.3.4. Given the minor version bump from v14.3.3, this is most likely a targeted refinement or bug fix build rather than a feature-heavy release β though that can't be confirmed until more owners receive it and report back.
Evidence
This detection is classified as strong undocumented evidence: Teslascope's automated system flagged the version string directly from vehicle telemetry, not from a rumor or social post. The dual detection β both the version number and the feature name β corroborates that the build is real and actively deployed to at least part of the fleet.
Context: Where v14.3 Has Been
To understand what v14.3.4 is likely building on, it helps to know what the v14.3 series has already delivered. According to verified reports, the v14.3 line introduced some of the most substantial FSD architecture changes in recent memory:
- 20% faster reaction time β Tesla rewrote its AI compiler and runtime using Multi-Level Intermediate Representation (MLIR), a significant under-the-hood change that accelerated the entire system's response speed.
- Upgraded neural network vision encoder β Improved handling of rare and low-visibility scenarios, better 3D geometry understanding, and expanded traffic sign recognition.
- Reinforcement Learning improvements β The RL training stage was upgraded, resulting in more natural driving behavior across a wider range of scenarios.
- Behavioral refinements β Reduced unnecessary lane biasing, less minor tailgating, and better responses to emergency vehicles, school buses, right-of-way violators, and small animals.
v14.3.3 β the previous detected version β was rolling out to early access testers and a broader North American fleet on builds 2026.14.6.6 and 2026.14.6.7 in late May and early June 2026. v14.3.4 appears to be the next step in that same rollout cadence.
How to Check If You Have It
- On your touchscreen, tap Controls β Software.
- Look for a pending update notification. If one is available, you'll see a yellow clock icon in the top bar.
- To check your current FSD version specifically, go to Controls β Autopilot β the active FSD version is listed there on supported hardware.
- If no update is showing, make sure your car is connected to Wi-Fi and parked. Tesla typically pushes updates overnight.
- You can also check Teslascope's tracker directly for the latest rollout percentage data as it becomes available.
