Tesla reduces the need for the steering wheel nag with FSD v12.4
Tesla has just rolled out its latest FSD software, v12.4 to employees. Elon Musk announced that this update would be available to employees this past weekend, with plans to release it to the public in small numbers later this week.
Surprisingly, the new update is version 2024.9.5, which is likely based on the earlier 2024.8 branch and not Tesla's latest 2024.14. The spring update (2024.14) brings various new features such as a new media player, a new parked visualization, Audible support, and a Preview of Sentry Mode events, among others.
However, FSD v12.4 brings itsownexcitement with two new major changes.
Vision-Based Attention Monitoring
The release notes show a new Vision-Based Attention Monitoring feature that replaces the steering wheel nag as Musk previously mentioned.
However, as we predicted, Tesla will still leverage the steering wheel to detect attentiveness when the cabin camera is inconclusive.
The car can only rely on the vehicle's cabin camera, and therefore remove the steering wheel nag under certain conditions:
the camera is not occluded
there is sufficient lighting
the driver is looking forward
the driver is not wearing sunglasses
the driver is not wearing a low-brim hat or another object that covers their eyes
If any of these situations occur, or if the vehicle doesn't have a cabin camera, then the vehicle will continue to use the steering wheel to determine driver attention.
Tesla is careful to state that images and video from the cabin camera are not saved or transmitted unless you enable data sharing.
Updated Strike System
With FSD v12.4, Tesla has also updated its Autopilot Suspension feature which is designed to enforce the responsible use of FSD.
The current system lets the driver receive up to five strikes (three strikes for vehicles without a cabin camera)before Autopilot and FSD become unavailable. If that happens, then FSD is unavailable for one week. Strikes are only removed once the driver has accrued five strikes, or when Tesla wipes out strikes for everyone, which happens about twice a year.
The new system is more gracious about removing strikes. The vehicle will continue to issue strikes whenever the driver isn't paying attention, however, now the vehicle will gradually remove strikes for the driver after a certainperiod of time.
Tesla states that one strike will be removed foreach 7-day periodthe driver goes without receiving a strike. So if FSD gets disabled due to strikes, the driver will still go one week without FSD, although now strikes are removed on an ongoing basis. This new strike system is expected to apply tovehicleswith and without a cabin camera.
Other New Features
Other new features areexpected in FSD 12.4 as well, which we outlined in our look at Tesla's FSD v12.4 article.
They include a focus on improved driver comfort by reducing the amount of hard braking, automatically seeking a parking spot when arriving at a destinationandmore. Driver interventions are also expected to be drastically reduced with Musk stating that Tesla expects to see a 5-10x improvementin interventions.
Eligibility
Unfortunately, due to FSD v12.4 being on branch 2024.9, it's expected to only be available to owners on update 2024.8 and below, which includes everyone currently on update 2024.3.25.
If no major issues are found with FSD v12.4, we could see it start to roll out to the public later this week.

easter-egg
By Karan Singh
Tesla’s latest set of updates has been fast-moving, with lots of bug fixes, and this fits with Musk’s philosophy of moving fast and breaking things. Some people are still on 2024.8.9, some are still on 2024.3.25, and some people are already on the 2024.14.8 Spring Update, and there’s also the brand-new 2024.20 update that just went out to employees for testing.
Let’s take a look at how Tesla’s software distribution system works, and why you are where you are.
Statistics
Before diving deep into how it all works, let’s get some statistics out of the way. We’ll be using the statistics we use here on the site, which are powered by TeslaFi.
The vehicles on each update
As we can see, the tracked fleet is about 30% 2024.14 – the spring update; 2024.8 – Tesla’s previous major update, which contains FSD V11; and 2024.3 – the FSD V12.3 update. The remaining fleet on 2023.44 or other updates is fairly negligible, at around 10%.
So, about 65% of the tracked fleet has access to FSD V12, depending on their country of origin. The remaining 25% of the fleet only has access to FSD V11 if they’re in an eligible region.
FSD Update Track
When someone subscribes or purchases FSD, Tesla enables the FSD feature on that vehicle’s firmware, which currently could be either FSD v11 or FSD v12.
Once you’ve subscribed to FSD, you’re generally on the ‘FSD Track,’ which means you’ll start receiving the latest FSD updates, but will generally receive Tesla features later than Tesla’s primary, non-FSD branch. Tesla’s FSD track has historically always been behind the main branch, and it has been that way since FSD Beta first went out to customers years ago.
Vehicle Eligibility
Not all vehicles are eligible for all updates, and this is a twofold reason. First, if you’re on an update that is on a newer branch, say 2024.8.9, you cannot go down to 2024.3.5. The version number is broken down to year, week number and revision. So update 2024.8.9 is the 9th revision of the update that was created on the 8th week of 2024.
In general, Tesla does not roll back versions, so if someone is already on update 2024.14, then their vehicle wouldn’t be eligible for FSD 12.4, which is update 2024.9.5. This is mainly due to potential issues since Tesla doesn’t thoroughly test rolling back software.
Your vehicle will always be eligible for updates on a later branch, even if you won’t necessarily receive that update – like the many owners on update 2024.8 or 2024.3 who haven’t received update 2024.14 yet.
The second factor is hardware. Vehicles on older hardware variants, or vehicles that are considered to be legacy, are just not eligible for some updates. This is something that Tesla decides as newer hardware is needed for newer features and support for legacy hardware may not be included in all updates.
If you’ve subscribed to FSD and you’re on update 2024.8.9 and wondering why you’re not receiving update 2024.14, that’s why. Tesla wants your vehicle to be eligible for the next FSD v12.4 update, which will be update 2024.9.5.
Vehicle Variants
Sometimes, updates are not sent out widely for the simple reason of hardware variants. Tesla’s fleet has become widely fractured over the years, with many different variants of vehicles on the road today. Some 2022 Model Y’s may have Matrix headlights, while some may not, and some may have USS, while others don’t. Most have HW3, but a few have HW4!
That’s 6 possible branching variants in one year – a total of 24 possible variants for just the 2022 Model Y, not including the Performance, Long-Range, Rear-Wheel Drive, 4680-cell Rear-Wheel Drive, and the odd 2022 Standard-Range Dual-Motor variants that are also all different! If you did the math, there are 362 thousand possible variants, but not likely more than ~40 or so actual builds that Tesla differentiates between for software for all vehicles.
Of course, Tesla has managed to pare down these variants through the 2023 and 2024 model years, with greatly simplified production chains, with the removal of USS in favor of Tesla Vision, the full move to Hardware 4 across all factories, and Matrix headlights becoming standard globally. But all those existing vehicles are not legacy, and still need updates.
That means a complex and well-thought-out update process has to be built in order to deploy a functional update to all these vehicle variants.
Bug Fixing
Besides the complexity of vehicle variants, Tesla also has to catch and fix bugs. No matter how good one is at software development, sometimes bugs just escape into the wild. And fixing those bugs is essential since they could leave a vehicle undriveable. Although a major issue is rare, Tesla has had some issues in the past, such as Automatic Emergency Braking being disabled due to a software issue. This is why Tesla rolls out updates gradually.
We’ve seen this play out with update 2024.14, which has received numerous bug-fix releases. Tesla will release an update to a set of cars, discover an issue, and stop the rollout. A few days later, another update is out with additional fixes, and so on.
Conclusion
So, if you’re stuck on update 2024.8.9 or 2024.3.25, and are wondering when you’ll get FSD V12 or the Spring Update, you’ll have to hang on – the author is also on 2024.8.9 with V11!
Elon Musk mentioned on X that FSD V12.4 should be the update the reduces FSD branching and will bring everyone to FSD V12 in general. 2024.9.5 is the FSD V12.4 update, and it looks like vehicles that are below that branch number should be collectively receiving the reduced-nag V12.4 update.
When we finally receive FSD V12.4, we’ll likely need to hang on for a little longer until FSD V12.4.1 or FSD V12.5 rolls along to have the Spring Update.
