Tesla FSD 12.4 has yet to go out to most eligible customers, but last night it took a big step toward achieving that. FSD v12.4.3 went out to the largest batch of FSD vehicles in North America so far, more than tripling the number of users on the latest Tesla FSD software.

Update: Another wave of FSD 12.4.3 just started going out this evening. This wave just started and it’s already the largest wave for this release. It’s estimated to be about 12% of FSD users.

Most vehicles with FSD in North America are now on update 2024.14.9 which includes FSD 12.3.6. However, these vehicles have been on this FSD version since it was first introduced with update 2024.3.25. About 25% of the Tesla fleet is on update 2024.14.9, which is almost exclusively vehicles that have bought or subscribed to FSD.

Before yesterday’s rollout, FSD 12.4.3 stood at about 1.3% of the entire fleet (not just FSD vehicles), but after yesterday’s release, about 3.3% of the fleet now has access to FSD v12.4.3. That appears to be about 10% of FSD users that now have access to FSD 12.4.3. If Tesla doesn’t see major issues with this wave, this could be the point where FSD 12.4.3 finally goes into wide release and becomes available to most users in the next week.

Roll Out and Eligibility

We should hopefully see another rollout of FSD 12.4.3 later today or tomorrow. This latest FSD release is update 2024.15.15, which means that it’s available to anyone on a 2024.14 update or earlier. Users who have recently subscribed or resubscribed to FSD and are on update 2024.20 won’t be able to receive FSD 12.4 or later until it becomes available on a branch that is higher than 2024.20.

Tesla doesn’t merge FSD software with the main Tesla branches often so historically speaking, it could be another month or even two before that happens.

Strike Reset

With FSD 12.4, Tesla has not only removed the steering wheel nag when the cabin camera can clearly see the driver, but it has also introduced a new strike system. Tesla will now remove one strike from the vehicle’s record (strikes are shared for all drivers of the vehicle), for every week the drivers’ of the vehicle go without receiving an Autopilot strike.

However, with the release of FSD 12.4.3, Tesla is also resetting all vehicle strikes to zero so that drivers’ have a clean slate to start with.

Vision-Based Monitoring

In place of the steering wheel nag is the improved vision-based monitoring, which tracks the driver with the cabin camera. In update 12.4.2, Tesla specifically updated the release notes for vision-based monitoring to mention that the driver’s arms also need to be visible to the camera. Tesla also changed some language around when it uses the vision-based camera and when it relies on steering wheel torque.

Whenever vision-based monitoring is active, the Tesla screen will display a green dot to alert the driver that the cabin camera is tracking them visually.

Prefer Update 2024.20 Over FSD 12.4?

Users who subscribe to FSD can sometimes pick whether they remain on the FSD track or the feature track of Tesla updates. If you subscribe to FSD and prefer to receive update 2024.20 instead of waiting for FSD 12.4.3, then you could let your FSD subscription lapse and Tesla will push update 2024.20 to your vehicle within a day. Keep in mind that your subscription needs to completely expire, not just be canceled.

The reason your vehicle remains on update 2024.14 is so that it remains eligible for FSD 12.4.3, however, when your FSD subscription expires, Tesla will send you the latest update your vehicle is eligible for. Right now that should be update 2024.20 for just about everyone. If you unsubscribe, you can immediately subscribe to FSD after you receive the latest update. However, doing so will mean that you won’t be eligible for FSD 12.4.3 or higher until the main FSD updates are based on a branch 2024.20 or higher, which may not be anytime soon.

Unfortunately, if you have bought FSD, then this isn’t an option for you. Hopefully, it won’t be long before another large wave of FSD 12.4.3 goes out.

Musk Confirms Tesla FSD V12.5 Is Being Tested on Chuck’s Turn

Yesterday, Elon Musk confirmed that FSD V12.5 is being tested on Chuck’s Unprotected Left Turn. This is a big step – as we usually see Chuck’s UPL getting tested a few weeks or months before the release of another set of software.

Chuck’s Left Turn

Chuck’s Unprotected Left Turn, or UPL, has regularly been seen as a challenge for FSD. Chuck’s UPL is a complex, 2-stage unprotected left turn into high-speed traffic. Ever since 2022, Tesla has been testing on Chuck’s UPL, which is in Jacksonville, Florida.

Vehicles are intersecting from different sides at different portions of the turn, making it one that is truly difficult for both humans and for FSD to get right. It can be a difficult challenge for regular drivers, and ensuring FSD gets it right every time Tesla releases a new build seems to have become a bit of a tradition for Tesla.

As such, we generally see Chuck’s UPL getting tested by Tesla’s ADAS testers prior to a new build being prepared for release to employees. These ADAS testers are pretty obvious – they’ve got manufacturer plates on, and the telltale 2-second halt at stop signs.

FSD V12.5 Around the Corner?

Although Tesla is already testing FSD 12.5, it doesn’t necessarily mean that v12.5 is around the corner just yet – there are still plenty of users that still need to receive FSD v12.4.3 before Tesla jumps to v12.5. About 20-25% of FSD users now have FSD 12.4.3, but most are still on update 2024.14.9 with FSD 12.3.6.

FSD v12.5 is expected to begin features such as fleet communication and the merger of city and highway software stacks, to FSD.

What we’re seeing in Florida on Chuck’s turn (Tesla refers to Chuck Cook in release notes) is likely just the ADAS testers working on the early builds of v12.5. As such, don’t get too wrapped up around v12.5 – most are still waiting for nag-free FSD for the most part.
