With every update that delivers noticeable improvements, owners also notice regressions. Sure, any FSDS V12 build is significantly better than the best V11, but it's still a long way until you can trust it with your life. As development progresses and FSD gets better, it becomes more difficult to assess performance, as it would require a lot of driving around to spot the differences.
This was probably why FSD V12.4's public rollout had been delayed more than expected. Elon Musk explained that the changes included in this update were significant, as Tesla had to retrain the models. This is why V12.4.1 never made it past the Wave 1 tester group. The subsequent update launched on June 27, and it appeared that it would see a wide release after some early adopters outside the Wave 1 group also got the update.
However, as some who tested it were quick to point out, the V12.4.2 proved disappointing, and Tesla stopped the rollout. This made some regular Tesla customers angry, blaming Tesla "insiders" for causing the halt. Fret not, Tesla released FSD V12.4.3 to employees on July 4 and the wider fleet over the weekend. "Third time's a charm," they say, and this surely looks so as thousands of cars in the US and Canada have installed the new update already.
As expected, the first reviews have been shared on social media, showing improvements in some areas and disappointments in others. That's pretty much what can be said for most FSD builds, except those that proved really bad. The reviewers praised the smooth driving and creativity in finding new routes that bring you faster to the destination, sometimes disregarding the navigation's indications. U-turns also appear vastly better, and the car now uses narrow gaps in traffic during right turns like a human.
However, there are also regressions. Some users point out patchy speed control, while others recounted instances when the FSD software reacted to other people's mistakes almost with road rage. The car could remain stuck at stop signs with no traffic around, something we've also seen with the V12.4.2. Even the most important feature introduced with V12.4 builds (no steering wheel nag) is imperfect. Owners reported that the new camera "nag" is too aggressive, telling you to pay attention even when looking straight at the road.
Here's my first impressions of Tesla FSD v12.4.3 after driving it around for 2 hours around Austin.

First off, this is based off just a few hours of testing and are my personal experience and thoughts. After more hours of testing, I'm sure I'll have other and different…
you might not like my FSD 12.4.3 first impressions… sorry in advance

- this version feels truly “unleashed” and is driving more like a human than ever, I saw an instance that seriously looked a little like road rage when it got cut off (will upload video tonight)
- speed…
