Tesla Rolls Out FSD 2026.20.6.10: Self-Driving App, SLOTH Profile, and HW3 Gets HW4 Intelligence
5 min read read
Tesla pushed software update 2026.20.6.10 on July 20, 2026, the fourth FSD-focused release in the 2026.20 cycle. Where the prior update (2026.20.6.6) brought FSD 14.3.5 to HW4 vehicles with reinforcement learning improvements, this build targets something different: it brings V14 Lite to HW3 vehicles by distilling the intelligence Tesla developed for its newer hardware onto the older camera and compute stack. The result is an update that touches FSD behavior, the user interface, and parking logic simultaneously.
HW3 Gets a Piece of HW4’s Brain
The headline engineering story in 2026.20.6.10 is what Tesla calls “distillation.” The intelligence embedded in HW4’s V14 neural networks — including reinforcement learning outputs and offline model improvements — was compressed and transferred to HW3 hardware, allowing older vehicles to directly benefit from training advances that were previously HW4-exclusive.
“The intelligence from HW4 V14 was distilled into HW3, allowing HW3 to directly learn how to handle scenarios using HW4 V14 as a guide — unlocking improvements that have been made to HW4 including Reinforcement Learning and offline models for HW3.” — Tesla official release notes, 2026.20.6.10
In practice this means HW3 owners should see smoother steering, fewer false slowdowns, improved lane centering, and better handling at complex intersections — capabilities that previously required HW4 hardware to access. Tesla confirmed the update is rolling out to HW3 Early Access users first, with wider availability expected to follow.
The FSD Self-Driving App
The most visible UI change in 2026.20.6.10 is the introduction of the FSD Self-Driving App, accessible via the App Launcher on the center display. The app serves three purposes:
- Subscription management: Single-tap subscription activation for owners who haven’t committed to the standalone FSD purchase
- Activation guidance: Step-by-step onboarding for drivers new to FSD Supervised
- Usage metrics: Ongoing stats tracking including FSD streaks, miles driven on FSD, and behavioral data
The inclusion of streaks as a tracking metric — rewarding consecutive safe FSD sessions — suggests Tesla is continuing the gamification approach introduced in earlier 2026 builds. Drivers who complete sessions without disengagements see their streak count increment in the app.
New Features at a Glance
| Feature | What It Does | Available On |
|---|---|---|
| FSD Self-Driving App | Stats tracking, subscription, onboarding | HW3 + HW4 |
| SLOTH Speed Profile | More conservative than Chill: lower speeds, cautious lane selection | HW3 + HW4 |
| Arrival Options | Choose Parking Lot / Street / Driveway / Parking Garage / Curbside | HW3 + HW4 |
| Start from Park | Engage FSD with brake pedal tap; disable brake confirm option | HW3 + HW4 |
| HW4 Distillation for HW3 | RL + offline model improvements transferred to older hardware | HW3 Early Access |
| Forward Camera Cleaning Panel | Service mode: live stream + zoom for camera cleaning | Select vehicles |
SLOTH: A New Speed Profile Below Chill
Tesla’s existing speed profiles — Chill, Standard, Sport — have been in place for years. Update 2026.20.6.10 inserts a new option at the bottom: SLOTH. The name is literal. SLOTH operates at lower target speeds than Chill and makes more conservative lane selections, choosing to stay in slower-moving lanes rather than proactively shifting for efficiency.
The driver’s profile now more heavily influences FSD behavior overall, and the right scroll wheel on the steering column allows direct adjustment of the Speed Profile from the center display visualization without navigating through menus. For new FSD users or those in high-pedestrian environments, SLOTH provides a meaningful step down from Chill’s already-conservative behavior.
Arrival Options: FSD Picks Where to Park
Arrival Options is the other significant behavioral change. Previously, FSD would navigate toward a destination and then disengage, leaving the driver to find parking. With 2026.20.6.10, drivers can pre-select how they want FSD to approach arrival: in a Parking Lot, on the Street, in a Driveway, inside a Parking Garage, or at Curbside. Preferences persist per destination, so a home address set to “Driveway” will default to that selection on future trips.
The Bottom Line for HW3 Owners
The 2026.20.6.10 update is the most consequential HW3-targeted release in over a year. HW3 owners who assumed they were at the end of Tesla’s software investment curve now have access to reinforcement learning outputs that were previously HW4-only. Combined with the Self-Driving App and SLOTH profile, this build meaningfully narrows the gap between HW3 and HW4 FSD capability — at least for the everyday driving scenarios that dominate most commutes. The wide release timeline has not been confirmed, but Early Access users reporting results should provide a preview of what the broader fleet can expect within weeks.
