Tesla has released version 14.3.3 of its Full Self-Driving (Supervised) driver assistance tech, and those who have already tried it say the update brings several improvements. However, it's also less naggy, giving drivers fewer alerts to keep them focused on the road when the system detects them looking away, and that's a concern for a system that is not truly capable of autonomous driving. Of course, Tesla CEO Elon Musk announced this as a positive development when responding to an early reviewer of the FSD (Supervised) update.
What's New For Tesla FSD v14.3.3
Tesla's Actually Smart Summon feature, which allows a Tesla user to move their car remotely via the Tesla app on their smartphone, has had issues with low-speed crashes, but over-the-air updates like this one have improved the feature enough for the NHTSA to close its probe. With the latest OTA update, users report that the Actually Smart Summon feature's 33 percent speed improvement from 6-8 mph makes the vehicle's movement through a crowded parking lot feel more human-like. It's also been said that, while the driver monitoring system is more relaxed, especially in Standard profile, FSD seems capable of detecting trouble before the driver can, at least in some cases; @BLKMDL3 on X (formerly Twitter) shared an experience of someone running a stop sign before he could see them, and FSD reacted to prevent a crash.

Other improvements include that "Standard is more relaxed with changing lanes," doing so less frequently, and steering, throttle, and brake inputs appear to be smoother, too, "even in tricky scenarios." FSD 14.3.3's parallel and perpendicular parking maneuvers are said to be more precise, and the more aggressive "Mad Max" setting, which lets FSD slice through traffic more assertively/aggressively, is also reportedly slicker. It's also said to be better during acceleration. As you might expect, there are still some areas for improvement, however.
Tesla FSD Is Improving Incrementally, Rolling Out to New Countries

One of the few gripes listed by this Tesla Model 3 owner is that "speed control in 55 mph speed zones needs more work," noting that the system "should be tamed and restricted a bit," and that pothole avoidance needs improving. Overall, though, this update seems smoother overall, more human-like in its actions, and easier to live with. That last bit is partly down to the reduced driver nags, but, as reported by Teslarati, Tesla FSD recently entered its second European country (Lithuania), meaning the entire FSD ecosystem is getting used more, creating more opportunities for learning, and that should translate to safer deployment both in Europe and here in the U.S.
