Tesla’s Latest FSD v14.3 Update: A Detailed Overview
Tesla enthusiasts and owners were eagerly anticipating the release of Tesla’s latest Full Self-Driving (FSD) version, v14.3, which was finally unveiled on Tuesday, 7th April. The wait was worth it, as this update brought significant improvements and enhancements to Tesla’s autonomous driving technology. Many Tesla owners had been eagerly awaiting this update, with some even expressing boredom with the previous version, v14.2.
The official release notes provided by the Tesla AI team detailed the various improvements and changes introduced in the FSD v14.3 update. One notable change that was not explicitly mentioned in the release notes was the adjustment made to Tesla’s infamous “Mad Max” speed profile. This aggressive speed profile, which was previously known for its high speeds, has been toned down in the v14.3 update, as reported by early beta testers.
One such beta tester, Chuck Cook, who has been testing Tesla’s FSD technology in Jacksonville, Florida, and surrounding areas, shared his experiences with the Mad Max mode on a highway drive. Chuck noted that the Mad Max speed profile in FSD v14.3 exhibited less aggressive behavior compared to previous versions. While driving in the right-most lane, the FSD system did not immediately shift back to the center lane after passing a truck, a behavior that was observed in earlier versions.
Despite the toned-down aggression, the FSD v14.3 still demonstrated assertiveness when dealing with merging vehicles. In a scenario where a vehicle attempted to merge into the middle lane, the FSD system did not yield. However, it also monitored a semi-truck ahead that was also trying to merge into the middle lane, showcasing the system’s ability to handle multiple simultaneous events.
Another Tesla owner, Spencer, tested the FSD v14.3 update in a more challenging scenario by driving through a narrow tunnel. The tunnel, located at a four-way intersection, posed a unique challenge for the FSD system. Using the Mad Max speed profile, the vehicle slowed down as it approached the tunnel, carefully navigating the tight space with confidence.
Overall, the FSD v14.3 update has received positive feedback from early testers, highlighting the system’s improved performance and capabilities. With each update, Tesla continues to refine and enhance its autonomous driving technology, bringing us one step closer to a future of fully self-driving vehicles.
