Tesla Full Self-Driving's biggest improvements from v13 to v14

"Tesla Full Self-Driving (Supervised) v14 has been out for several weeks now, and there are a tremendous number of improvements, as we have now reached the fourth iteration of the semi-autonomous software. Tesla began the v14.1.4 launch last night, which included minor improvements and addressed brake-stabbing issues many owners have reported. In my personal experience, the stabbing has been awful on v14.1.3, and is a major concern."

"However, many things have improved, and only a couple of minor issues have been recurring. Many of the issues v13 addressed are no longer an issue, so Tesla has made significant progress. Here are some of the most notable improvements Tesla made with v14 from v13: Better Lane Switching on Highways One of my biggest complaints with v13 was that the "Hurry" Speed Profile would often stay in the left lane, even when there were no passing cars. The legality of cruising in the left lane fluctuates by jurisdiction, but my personal preference is to drive in the right lane and pass on the left."

"That said, Tesla has improved FSD's performance with more courteous lane behavior. It no longer camps in the left lane and routinely gets back in the right lane after passing slower cars. More Awareness for Merging Traffic and Makes Courteous Moves There have been times when FSD has been more aware of merging traffic, and even cross traffic, than most human beings. Here are a few examples - Full Self-Driving lets a car out of cross traffic during a busy time of day. This road tends to get very congested, especially during rush hour, so the car that was let in by FSD would have been sitting there for likely a minute longer if my Tesla had not let him in:"

Tesla Full Self-Driving v14 brings many improvements over v13, marking the fourth iteration of the semi-autonomous software. The v14.1.4 rollout delivered minor refinements and specifically targeted brake-stabbing complaints reported by owners. Brake-stabbing behavior on v14.1.3 was particularly severe for some users, and the update aims to reduce those occurrences. Most issues addressed in v13 are now resolved, leaving only a few minor recurring problems. Highway lane-switching has become more courteous, with FSD returning to the right lane after passing. Merging and cross-traffic awareness have notably improved, enabling more courteous yields in congestion.
