Tesla FSD v14.3.5 Is Here, and Early Drives Show Its Best and Worst

Tesla FSD (Supervised) v14.3.5 has barely reached early owners, and it is already doing two very different things on camera: threading a difficult driveway and parking inside a cart return.

That is the story of this release so far. Some of the driving looks impressively calm and aware.

Other moments show exactly where Tesla still has work to do.

The build is arriving through software update 2026.20.6.6. Version 14.3.5 may be a point release, but it brings the FSD branch onto Tesla’s broader 2026.20 feature set while owners test another round of driving refinements.

Not a Tesla App reports that the rollout began over the weekend. Beyond the driving code, the package adds parked-vehicle blind spot warnings to more models, encrypts Dashcam and Sentry Mode clips stored on USB drives, expands parental controls, and puts a self-driving indicator with Tesla’s blue route inside the mobile app.

Owners can also open the multi-camera preview while the car is moving. The driving model is unchanged, but the person behind the wheel gets a useful look at the feeds surrounding the car instead of seeing the full grid only in Park.

The same report followed an early tester through three runs at a turn-lane problem spot. A repeatable steering twitch from v14.3.4 did not return.

The tester also completed four parking attempts that were mostly well centered, found the more assertive drive profiles properly assertive, and saw cautious behavior at unprotected turns.

Then came this driveway test. The route is tight enough to expose hesitation or poor placement quickly, yet the Tesla works through it with measured, deliberate movement.

A driveway might look easy from the curb. For a driving system, narrow geometry, nearby obstacles and limited room to recover can turn it into a planning test.

Smooth progress there is worth noticing.

The encouraging behavior carried onto public roads in another early test, although the results were not clean across the board.

Teslarati put roughly 50 miles on v14.3.5 and found the car more aware of its surroundings in several specific encounters. It slowed and went wide around a work truck positioned near a turn, then backed up to give a tractor-trailer more room for a difficult maneuver.

Those are small acts of road courtesy, but they require the car to understand more than lane paint. It has to read another vehicle’s likely path, judge the available space and make a move that helps rather than creates a new problem.

The same drive found that speed profiles could still be inconsistent, forcing more adjustment than the writer wanted. Parking was rougher.

Multiple owners shared examples of the system reaching the destination but choosing a poor place to finish the trip.

One of those examples could hardly be clearer. Instead of taking an ordinary parking space, the Tesla stopped inside a shopping-cart return.

It is funny for a second. It is also a genuine planning failure.

The car got to the destination and completed a parking maneuver, but it missed the meaning of the space it selected. A human sees the rails, carts and surrounding layout and knows that area is off limits.

The driving model still has to connect those visual clues to the right decision.

That sharp contrast makes v14.3.5 interesting. The same build can negotiate a cramped driveway, accommodate a large truck and behave with impressive courtesy, then make a basic parking choice no attentive driver would accept.

Two clips cannot define an entire software release. Early owner footage naturally surfaces the standout wins and the strangest failures.

The next question is whether the smoother behavior holds across more roads and whether these parking misses become less common as the rollout grows.

Tesla Support continues to describe the system as supervised and says it does not make the vehicle autonomous. Drivers have to remain attentive and responsible for the car’s speed and control.

That warning is not filler when a build can look brilliant in one driveway and confused in the next parking lot. Owners testing v14.3.5 should be ready to take over, especially near lots, drop-off zones and unusual curb layouts where a destination pin does not explain where the car should actually stop.

Still, the best moments are genuinely exciting. Better placement, calmer turns and more cooperative behavior around other vehicles are the subtle improvements that make supervised driving feel less robotic and more useful.

FSD v14.3.5 looks like a solid step forward with one obvious assignment left on the board: keep the new composure, and teach the car the difference between a parking space and the place where the carts go.
