Tesla's FSD v12.5.3 features Actually Smart Summon, a type of summon available on vehicles without ultrasonic sensors. The update is currently going out to early-access customers. It is being rolled out to both AI4 and HW3 cars. Actually Smart Summon has greatly improved capabilities over its predecessor and uses end-to-end AI rather than relying on hand-coded features to control vehicles. The feature is expected to roll out to North America first before gradually rolling out to additional countries.
