Tesla has begun rolling out version 14.2.2 of its Full Self-Driving (FSD) software as part of update 2025.45.5, introducing a series of refinements aimed at improving driving smoothness and system reliability.
According to feedback from early users, the update delivers noticeable improvements in steering smoothness, cornering behavior and lane discipline. Drivers report fewer instances of abrupt corrections or lane-hugging behavior that had been observed in earlier versions of the 14.2 release.

One of the most notable changes involves lane changes and merging behavior. Users say the system now executes maneuvers more decisively, with fewer aborted attempts or hesitation mid-maneuver. The improvements are particularly evident when using more assertive driving profiles, such as “Hurry” or “Mad Max,” where previous versions were criticized for indecision that required frequent human intervention.
Parking and low-speed maneuvers have also been refined. Testers report more consistent centering within parking spaces and quicker decision-making when selecting parking spots. Destination-based adjustments, such as repositioning near arrival points, appear more reliable, though performance can still vary depending on environmental conditions.

Despite the progress, the update does not fully eliminate existing limitations. Map-related issues remain a common source of disengagements, including incorrect routing, missed turns, or inefficient navigation in complex parking areas. In dense traffic, the system can still behave conservatively when merging, occasionally disrupting traffic flow.
Overall, early feedback suggests that FSD v14.2.2 represents a meaningful refinement rather than a fundamental redesign. While not a dramatic leap forward, the update appears to address several pain points identified in earlier releases, improving consistency and driver confidence as Tesla continues to iterate on its driver-assistance software.
