Tesla is rolling out FSD V14.3.3 today, and among the changes is a 33% speed increase to Actually Smart Summon — the feature now tops out at 8 mph, up from the 6 mph cap (less impressive when you put it like that).
The speed bump is part of a broader update (software version 2026.14.6.6) that also merges the Spring 2026 software features with the FSD branch for the first time.
Actually Smart Summon gets faster
Actually Smart Summon (ASS) has been one of Tesla’s most polarizing features since it launched in September 2024. It allows a Tesla to navigate a parking lot autonomously to come pick up the owner or drive to a pin they drop on the map.
The problem has always been speed. At 6 mph, the car crawled through parking lots so slowly that it was often faster to just walk to the vehicle. In busy retail environments, other drivers would stack up behind the Tesla, creating awkward situations.
You also need to always keep an eye on the vehicle and be ready to stop it through the app, as it has been known to get into fender benders.
With FSD V14.3.3, Tesla has raised the cap to 8 mph (13 km/h). While 2 mph sounds marginal on paper, it represents a 33% increase in top speed and makes a noticeable difference in real-world use. At 8 mph, the car covers a 200-foot parking lot in about 17 seconds versus 23 seconds at the old limit — shaving roughly 6 seconds off every summon session.
The improvement builds on the major architectural changes introduced in FSD V14.3, which rewrote the AI compiler with MLIR for 20% faster reaction time. In the V14.3.2 update, Tesla unified the AI model powering consumer FSD, the commercial Robotaxi fleet, and Summon into a single architecture — giving the parking lot feature access to the same neural network that handles highway driving.
That unified model is what gives Tesla the confidence to raise the speed limit. The system can now process its environment faster and react more quickly to obstacles, pedestrians, and other vehicles in parking lots.
AI4 hardware only
The speed increase is limited to vehicles equipped with AI4 (Hardware 4) compute, which is Tesla’s only hardware supporting v14. Owners still running HW3 should not expect the same 8 mph cap.
This is consistent with Tesla’s broader strategy of pushing advanced FSD features to AI4 first. The company has been promising a “V14 Lite” for HW3 vehicles internationally, but that update remains months away.
NHTSA investigation cleared the path
The speed increase comes about six weeks after NHTSA closed its investigation into Actually Smart Summon following 159 documented incidents. The agency found zero injuries and zero fatalities across the feature’s entire history, with incidents limited to minor property damage — mostly involving parking gates, adjacent vehicles, and bollards.
Tesla addressed the issues through six over-the-air software updates during the investigation period, and NHTSA determined those fixes were adequate. No recall was issued.
With the regulatory cloud lifted, Tesla now has room to push the feature’s capabilities further — and raising the speed limit is the first tangible step.
Other FSD V14.3.3 changes
The speed increase isn’t the only change in today’s update. FSD V14.3.3 also introduces a live intervention-free streak counter that appears on the main display, tracking how many consecutive miles the driver has covered without disengaging FSD. The counter resets to zero the moment the driver takes over. Tesla is clearly gamifying the experience to discourage unnecessary interventions.
The update also revises the mandatory disengagement feedback menu that Tesla introduced in V14.3.2. The options have been simplified from “Preference, Discomfort, Critical, and Navigation” to “Navigation, Parking, Critical, and Other”.
Electrek’s Take
The speed increase to Actually Smart Summon is a welcome change, but I don’t think it makes the feature much more useful. I rarely use it. Personally, it doesn’t bring much value to me.
We also note that this improvement is AI4-only, which continues the frustrating two-tier experience for Tesla owners. If you bought a car with HW3 and paid for FSD, you’re watching the feature you paid for improve on hardware you don’t have. Tesla says it will build dedicated retrofit factories to address this, but that’s cold comfort for owners who have been waiting years.
Let’s not forget that Elon Musk promised HW3 owners that they would be able to summon their cars across the country years ago. Now, this seems like a ridiculous proposition.
The intervention counter is a nice addition, but what we really want is Tesla releasing the full intervention data from the fleet. That would be really useful data in actually tracking Tesla’s FSD progress.
