Tesla FSD V14.3.3 Boosts Actually Smart Summon Speed to 13 km/h
Tesla's latest FSD V14.3.3 update increases Actually Smart Summon speed by 33% to 13 km/h, making parking lot summon less awkward. Available on HW4 only.
Tesla has started rolling out FSD V14.3.3, and one of the key updates involves Actually Smart Summon. The parking lot summon function now reaches speeds of 13 km/h, up from the previous 10 km/h. On paper that's just a 3 km/h increase, but it represents a 33% boost.
Actually Smart Summon lets the car drive itself to the owner in a parking lot or to a location marked in the app. The problem was its speed: at 6 mph, the Tesla moved so slowly that it was often easier to just walk over. In crowded store parking lots, that sluggishness also annoyed other drivers.
Now, a 61-meter parking lot section takes about 17 seconds instead of 23. That doesn't turn Smart Summon into a full-fledged autoparking feature, but it makes the function less awkward in real-world use.
The speed increase is tied to updates in FSD V14.3. Tesla reworked the AI compiler using MLIR, which resulted in 20% faster response. In V14.3.2, the company merged the AI model for user FSD, Robotaxi, and Summon into a single architecture. According to the source, that is what allowed the speed limit to be raised.
But there is an important limitation: the speed increase is only available for cars with AI4, meaning Hardware 4. Tesla owners with HW3 won't get the higher limit in this update. For them, the company promises a lighter version of V14, but the timeline remains unclear.
The update comes about six weeks after NHTSA closed its investigation into Actually Smart Summon. The agency looked into 159 incidents and found no injuries or fatalities; damage was mostly minor—gates, adjacent cars, bollards. Tesla addressed the issues through OTA updates, and no recall was needed.
FSD V14.3.3 also introduces a miles-without-intervention counter. It shows how many miles the car drove on FSD without disengagements and resets when the driver takes manual control. Tesla is clearly trying to make using autopilot more 'game-like,' but for owners, the main question remains: how quickly are features improving on their specific hardware?
