Tesla has officially started rolling out its highly anticipated Full Self-Driving (FSD) Supervised V14.3.3 software update, which includes the major Spring Update for the company. This new update, labeled as software version 2026.14.6.6, brings with it key performance refinements to the autonomous driving suite and introduces a significant speed upgrade for low-speed parking lot maneuvers.
One of the most notable changes in this release is an update to Actually Smart Summon (ASS). This feature allows Tesla owners to summon their vehicles autonomously within a parking lot. The key improvement in this update is a speed increase, with the feature now capable of reaching a top speed of 8 mph (13 km/h), up from the previous limit of 6 mph. Early user feedback suggests that this increase in speed significantly enhances the practicality and natural feel of using the feature in busy retail areas.
In addition to the speed upgrade for parking lot navigation, the FSD software update also brings enhancements to the artificial intelligence (AI) system. The update includes an upgraded Reinforcement Learning stage for the neural network, which aims to improve decision-making in various driving scenarios. Furthermore, the update introduces an updated vision encoder that enhances the vehicle’s understanding of 3D geometry, allowing for improved perception of complex environments and traffic signs with greater accuracy.
Tesla has also made improvements to its AI compiler, which results in a 20% reduction in reaction times and smoother model iteration. The update focuses on enhancing passenger comfort by reducing lane-biasing and tailgating behaviors, while also improving the handling of rare and unusual objects on the road.
FSD 14.3.3 is currently being rolled out in the USA and Canada. Tesla CEO Elon Musk has praised the update, referring to it as “a banger.” With these new enhancements and improvements, Tesla continues to push the boundaries of autonomous driving technology, bringing us one step closer to a future of fully autonomous vehicles on the road.
