Tesla has begun rolling out Full Self-Driving (Supervised) version 14.1.4 to more owners, focusing on refinements like smoother driving and issue fixes. This update follows closely after v14.1.3 and highlights progress from v13, including better lane switching and object avoidance. The rapid iterations aim to enhance semi-autonomous performance ahead of upcoming versions.
Tesla's Full Self-Driving (Supervised) v14 has been available for several weeks, marking the fourth iteration of the semi-autonomous software. On October 26, 2025, the company launched v14.1.4 with software build 2025.32.8.16, a minor update that addresses reported brake-stabbing issues from v14.1.3 and refines overall performance without new features in the release notes.
This point release expands access to FSD v14, building on the wider rollout of v14.1.3 via build 2025.32.8.15 earlier in the week. Tesla's update cadence has accelerated, averaging a new FSD version every three to four days recently. Initial tests show v14.1.4 delivering smoother and more confident driving compared to v14.1.3, though some hesitation persists in complex scenarios.
Key improvements from v13 to v14 include better highway lane switching, where the system no longer lingers in the left lane after passing slower vehicles and returns to the right lane more routinely. Enhanced awareness of merging and cross traffic enables courteous moves, such as yielding to vehicles during rush hour congestion or on busy expressways. In Pennsylvania's Lancaster area, v14 demonstrated confident overtaking of slow-moving Amish buggies and mail trucks without intervention.
Object avoidance has improved significantly; for instance, the system swerved smoothly around a dead animal carcass on a highway, a maneuver that felt natural and unalarming. Speed consistency is better on local roads and highways, with quicker acceleration to limits and reduced fluctuations—v14 eliminated the separate Max Speed setting, making adjustments more intuitive via the scroll wheel.
Tesla CEO Elon Musk has confirmed FSD v14.2 will arrive in a few weeks, followed by v14.3, both expected to make the software feel more 'sentient.' These incremental updates underscore Tesla's push to polish its neural network for real-world reliability.
