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 brimwithout sunglasses, or other objects covering thetheir eyes). Outside of theseIn other circumstances, the driver monitoring system will continue toprimarily 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.
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.

Another quarter has passed, and that means it’s time to submit questions and vote for Tesla’s Q2 2025 Earnings Call. While Q1 was a tough quarter for the company, Q2 saw some recovery in sales, although there’s still some work to be done.
However, there’s always a lot to be excited about during Tesla’s Q&A session, where we usually learn a lot about future software improvements and upcoming vehicles. We may hear more about FSD Unsupervised, Robotaxi, or the more affordable vehicle, or its upcoming larger 6-seater Model Y, the Model Y L. Tesla also mentioned a potential FSD price hike back in the Q1 2025 Earnings Call, so that could be something that is brought up as well.
Tesla’s Q2 So Far
Tesla has already released their Q2 2025 Production and Delivery numbers, which were up from Q1 of this year, but still down compared to Q2 last year.

How to Submit & Vote
Tesla lets shareholders submit a question that will be voted on and may be answered during the Q&A session. To submit your own question or vote on an already submitted question, you’ll need to be a verified shareholder. You can go to Say’s platform and link your brokerage accounts.
Once it is verified, you’ll be able to log in and vote your shares on your own question, or on someone else’s question.
Here’s the link to get started on Say’s Tesla Q&A. You must submit your questions and votes by July 23rd, 2025, at 4:00 PM EDT.
Top Questions So Far
Unsurprisingly, people have already been submitting questions, and here are the top ones so far.
Can you give us some insight how robotaxis have been performing so far and what rate you expect to expand in terms of vehicles, geofence, cities, and supervisors?
What are the key technical and regulatory hurdles still remaining for unsupervised FSD to be available for personal use? Timeline?
What specific factory tasks is Optimus currently performing, and what is the expected timeline for scaling production to enable external sales? How does Tesla envision Optimus contributing to revenue in the next 2–3 years?
Can you provide an update on the development and production timeline for Tesla’s more affordable models? How will these models balance cost reduction with profitability, and what impact do you expect on demand in the current economic climate?
Are there any news for HW3 users getting retrofits or upgrades? Will they get HW4 or some future version of HW5?
When do you anticipate customer vehicles to receive unsupervised FSD?
And here are some other ones we found interesting:
Have any meaningful Optimus milestones changed for this year or next and will thousands of Optimus be performing tasks in Tesla factories by year end?
Are front bumper cameras going to be necessary for unsupervised full self driving? If so, what is the companies plan to retrofit vehicles that do not have them?
Will there be a new AI day to explain the advancements the Autopilot, Optimus, and Dojo/chip teams have made over the past several years. We still do not know much about the HW4.
Earnings Call Details
Tesla will hold its earnings call on Wednesday, July 23rd, at 4:00 PM EDT. It's still early for an access link, but we’ll make sure we have a link up on the site before the earnings call that day.
If you do miss the earnings call, no worries. We will provide a full recap following the call, and we’ll also do some in-depth dives into what was said and what we know.
Tesla’s Summer Update, 2025.26, has finally launched, bringing with it a batch of interesting new features for some, and a bunch of quality-of-life improvements for everyone else.
Grok AI Assistant
The star of the Summer Update is Grok, xAI’s conversational AI assistant, which has now landed in Tesla vehicles. For now, it's available in any Tesla that has an AMD processor and is potentially coming to Intel-based vehicles in the near future. The feature is also only available in the U.S., but it’s expected to expand to other regions — hopefully soon.
Grok is in its first iteration as an in-vehicle assistant, and for now, cannot control the vehicle, which means that Tesla’s voice command system is still intact. However, there is a lot it can do already. Grok is activated by pressing and holding the voice button (right scroll wheel on older vehicles), while a short press of the button is still reserved for voice commands. Grok will support a wake word in the future, letting you activate it without pressing a button.
You don't need to sign into Grok to use it in your Tesla!

Once Grok is open, which can also be done by tapping the Grok app icon, users can tailor the AI personality according to their preferences by selecting a persona and voice of their choice.
There are also several other settings for Grok under the settings button. You can enable NSFW mode, Kids Mode, or disable access to your vehicle’s location.
Grok has contextual awareness of your vehicle location, which means it can provide relevant answers to questions like “Where should I go for dinner?”
Logging In Not Required
Grok is free with Premium Connectivity, or if you’re using your phone’s hotspot feature or connected to WiFi, so anyone can try it for free. In fact, you don’t even need to log in to start using Grok. However, logging in adds some additional features.
If you’d like to log in, you can do so by scanning the QR code in the vehicle, which will provide chat management and transcripts, SuperGrok access (if you pay for a subscription), and better privacy control.
Tesla has added a new Light Sync feature that pulses the vehicle’s ambient lighting in sync with the music being played. This option is turned on under Toybox > Light Sync. There are also a few options, including the ability to match the ambient light colors to the album’s artwork, instead of using your selected color.
In addition, in Park you can enable Rave Cave when parked, which cranks up the ambient lighting brightness to the maximum.
Dashcam App Update
The Dashcam app now allows you to adjust playback speeds, just like the older Dashcam Viewer, which is still used on Intel-based vehicles.
In addition to adjusting playback speed, you can now adjust the video view so that it’s displayed without being obstructed by the buttons at the top (video below). The difference is small, but could be useful if you’re trying to see something slightly out of view or that’s hidden behind the top Dashcam buttons.
While the Cybertruck has also received the updated Dashcam Viewer with this update, it does not have the new B-pillar camera recordings like other HW4 cars.
Sentry Mode is getting one of the best uses of the vehicle’s ambient lighting that we’ve seen so far. The ambient lighting will now slowly pulse red while Sentry Mode is activated to grab someone’s attention, instead of just relying on the vehicle’s display.
While you can disable Sentry Mode sounds, we’d love to see an even more stealthy Sentry Mode that also disables the ambient lighting and screen, allowing the vehicle to record without anyone being aware.
Since the ambient lighting is being used in this case to make people more aware of a feature, Tesla could also use it in other modes, such as Dog Mode.
There are a lot of potential uses for ambient lighting. Tesla can make it glow while the vehicle is charging, with the brightness potentially related to the vehicle's charge level.
When you navigate to a Supercharger, new icons in the charger list will indicate locations that require valet service or pay-to-park access.
Upon arrival at the location, a notification will appear on your screen, displaying important details such as access codes, parking restrictions, level/floor information for parking garages, and restroom availability. This information will also be available on the site card in the navigation.
Equalizer Presets

Tesla has moved the audio settings from the music player, directly into the vehicle settings — making them much easier to find. In addition to creating a new “Audio” section in settings, you can now create and save equalizer presets.
Each preset can have a name, custom EQ settings, and a setting for immersive audio.

Onboarding Guide
Not a Tesla App
Tesla has introduced a new Onboarding Guide for new owners. The guide covers driver settings, touchscreen use, steering wheel and seat setup, and how to control key portions of the vehicle, including lights, wipers, and Autopilot features.
The Onboarding Guide is automatically initiated when a new owner accepts delivery of a Tesla, or can be manually initiated at any time by going to Controls > Service > Onboarding Guide.
This appears to only be available for the new Model 3 and new Model Y.
In typical Tesla fashion, this 2025.26 update is rolling out gradually in small waves initially. Three waves have already gone out, so all signs are looking good for it going into a wide release soon.
