After a month-long delay, Tesla sent FSD v12.4.2 to employees yesterday with update 2024.15.10. After just a few hours of the update going out to employees, Tesla started sending it to OG testers as well, who were already on FSD v12.4.1.

Issues Behind Delay

On X, Elon Musk broke down some of the details behind the delays. He mentioned that part of the issues behind the V12.4.2 delays were based on training. Tesla was seeing fewer interventions with FSD v12.4, but the release suffered from driving smoothness, which ironically was supposed to be one of the key features of this release.

Musk explained that part of the issue was due to too much focus on interventions, and not enough on normal driving. He compared it to training a doctor on emergency room patients, versus training on regular preventative care.

Vision-Based Attention Monitoring Changes

With FSD update 12.4.2, Tesla changed some of the language used for its Vision-Based Attention Monitoring in the release notes. Here’s a breakdown of some of the key points in the language. The changes to the release notes are below. Phrases or words that were removed are crossed out, while those added are in bold.

“When Full Self-Driving (Supervised) is enabled, the driver monitoring system now primarily relies on the cabin camera to determine driver attentiveness. This enhancement is available on vehicles equipped with a cabin camera and only when the cabin camera has clear and continuous visibility of the driver's eyes Cabin camera must have clear visibility (e.g., the camera is not occluded, eyes, arms are visible, there is sufficient cabin illumination, and the driver is looking forward at the road ahead and not wearing sunglasses, a hat with a low brim without sunglasses, or other objects covering the their eyes). Outside of these In other circumstances, the driver monitoring system will continue to primarily rely on a combination of torque-based (steering wheel) and vision-based monitoring to detect driver attentiveness. When the cabin camera is actively monitoring driver attentiveness, a green dot appears next to the steering wheel icon on the touchscreen.

If the cabin camera detects inattentiveness the driver to be inattentive, a warning will appear. The warning can be dismissed by the driver immediately reverting their attention back to the road ahead. Warnings will escalate depending on the nature and frequency of detected inattentiveness, with continuous inattention leading to a Strikeout.

Cabin camera images do not leave the vehicle itself, which means the system cannot save or transmit information unless you enable data sharing.

Arms Need to be Visible and Other Changes

There are various interesting changes here. While some of the changes are just improved wording to make the feature clearer, there are others that are worth highlighting which could point at changes to Tesla’s vision-based monitoring.

The first is the addition of “arms are visible.” Apparently, Tesla now wants to be able to see your arms to better detect attentiveness. Tesla may want to see that your arms are on the steering wheel, or they maybe they want to make sure your arms are moving so that someone isn’t able to post a static photo in front of the cabin camera to circumvent the attention monitoring. The reason isn’t clear, but looks like having your arms visible is now a requirement.

There are other small changes like the removal of a “hat with a low brim,” which was replaced by more generic wording that says the driver’s eyes must be visible.

However, near the end, Tesla removed the portion that said the driver monitoring system will rely on a combination of torque-based (steering wheel) and vision-based monitoring. This was changed to simply say that Tesla will rely primarily on torque-based (steering wheel) monitoring when vision-based monitoring is unavailable. It’s not clear whether this is just semantics and the wording now better describes how the vision-monitoring feature works, or if Tesla made changes so that the vehicle is simply either doing vision monitoring or steering wheel torque detection, and it doesn’t try to combine the two sources to detect whether the driver is paying attention.

Even more interestingly, the last line that says “cabin camera images do not leave the vehicle itself, which means the system cannot save or transmit information unless you enable data sharing,” has been removed. This could point to Tesla saving images of the cabin camera to improve its AI training model.

Tesla will display a green dot on the screen whenever its using its vision-based monitoring system.

Release Date

Either way, we’re glad to finally see FSD v12.4.2 going out to employees and early-access owners. The release is expected to have far fewer interventions and improve vehicle smoothness during braking and acceleration. If there are no major issues found, this update could go wide to all customers with FSD and on update 2024.14 or lower in the coming weeks.

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.

Tesla Update 2024.26.1: Changes and More Information About Tesla's Summer Update

By Karan Singh

Tesla has been preparing another large update with its upcoming 2024.26, but as Tesla gets ready to release it to customers, it looks like we may see some changes. We’ve previously called this the Summer Update, and we’re going to stick with that.

Leave your Spring umbrella behind, and grab some sunglasses (or not, if you have FSD in North America) and let’s take a look at update 2024.26.1.

YouTube Music

It looks like YouTube Music, which was being tested in update 2024.26, isn’t available in 2024.26.1. YouTube may have been in early stages of testing or Tesla found some bugs with the feature that need to be addressed before a public release.

YouTube Music is still coming, but right now it looks like it’ll arrive in a point-release update, (e.g. 2024.26.X). This way, at least all the other features will arrive for everyone, rather than delaying the entire release for a few bugs with YouTube Music.

While we’re sad to see the delay for this music app, this is exactly why Tesla tests things in advance with their QA team and fleet of wave 1 employees. We’ll be glad to see it arrive in our cars when its bug-free, and at least we’re still getting Amazon Music with update 2024.26.1.

Updated Climate Panel

There’s a new Climate screen in update 2024.26, however, it looks like it’ll be just for the Model 3 and Model Y initially. The Model S and Model X use practically the same interface, but it may need some adjustments for the larger screen before it’s released. It’s not clear whether it’ll be available for the Cybertruck out of the gate.

We haven’t seen any images of the updated climate panel yet, but it looks like it’ll be a drastic departure from the screen we know today. It’s expected to include options to automate preheating and precooling of the vehicle on certain days and times and it could make other options more intuitive such as turning off vents on the passenger side (tap and hold the airwaves, but only works on some vehicles).

Other often requested features are to make it easier to turn on the Keep Climate, Dog Mode, and Camp Mode options when the vehicle is put into park.

Many customers have also requested passenger presets so the vehicle could remember settings for different passengers. This could be used for features like passenger climate settings, seat position, seat heater and more, but instead of multiple passenger settings, we may see Tesla add Passenger Profiles that could be used for a wide variety of features. Back in 2021, Musk agreed that it would be a good addition.

Castle Doombad Classic

One addition we saw from update 2024.26 to 2024.26.1 was the addition of the full Castle Doombad Classic game. Castle Doombad has you play as the villain as you defend your castle, but it’s only available on AMD Ryzen-based vehicles (MCU 3). It was released in the 2023 Christmas update and with this 2024.26.1 update the game goes from a demo to the full classic game.

Weather Forecasting

Finally, the Weather Forecast app – a pop-out display when you tap the temperature reading – will be arriving with support for North America, Europe, and other regions. Likely, this will include most regions, but you’ll need to shell out for Premium Connectivity.

The AQI (Air Quality Indicator) is already available in China and should be available in most regions as well, but it will also require Premium Connectivity. You can read more about the weather and AQI features here.

Release Date

Tesla appears close to starting the public release of this 2024.26.1 update. Tesla has recently released major versions (like 2024.26) to employees only and then released a bug fix update as a point release before making it available publicly.

Update 2024.26.1

FSD Supervised 12.3.6
Installed on 0% of fleet
0 Installs today
Last updated: Jul 16, 1:52 am UTC

We could see Tesla release 2024.26.1 as early as this week if further issues aren’t identified, although, in typical Tesla fashion, it’ll be a very gradual release.
