Tesla recently launched another round of FSD Trials for both new and current customers. Like before, the trial is for 30 days. However, Tesla is now sending out emails to users that the trial is being extended — letting users get FSD for about an extra week.
FSD is built into every Tesla vehicle, but it comes with a hefty up-front price tag or a more economical subscription of $99 USD/CAD per month. Since not every customer has tried out the latest version of FSD, Tesla is sending out more trials, hoping it will stick with some customers. A longer trial could do just that, as users start relying on it for everyday drives instead of just trying it out.
The timing of the trial and extension is also interesting. Thanksgiving takes place in the United States on November 28th, which means many of these trials will still be active during the holiday. Having this trial active during the Thanksgiving holiday could expose many non-Tesla owners to FSD.
Update: This article has been updated to accurately reflect the 30-day trial. Users who are receiving the trial now are getting a 30-day trial. For users who received the free trial earlier, Tesla has extended it by 30 days from the day of the email, which ends up being about an extra week.
FSD V12.5.4.1
When a user receives the FSD trial, Tesla updates their cars to 2024.32.10, which includes FSD V12.5.4.1, alongside hands-free driver monitoring with sunglasses, as well as Actually Smart Summon. Essentially, this is a big moment for Tesla to show off the latest FSD features to as many customers as possible.
At the recent Q3 2024 Earnings Call, Tesla also confirmed that the FSD rate has been up since the We, Robot event. This is likely due to more people seeing the robotaxi and the fact that there were no incidents while moving thousands of people. This, plus the recent success of FSD V12.5, which has a lower intervention rate than earlier versions, is opening more people up to the idea of autonomy.
Trial Extension
Tesla is announcing the trial extension to some users through email or a message in the Tesla app, so keep an eye out for both. The email and message are going out to users in North America who subscribe to FSD or don’t have FSD at all. It does not include customers who have bought FSD since those owners already have it for the life of the vehicle.
Tesla appears to be phasing in the FSD trial, as not all users have received it yet, but we expect most users to receive it in the next few weeks.
Enable the Trial
Once you receive the email, check your vehicle to see whether it asks you to activate FSD. Keep in mind that it may take up to a day for FSD to show up in your vehicle. Once it does, FSD will be activated on your current software version, which is likely FSD 12.3.6, but update 2024.32.10 should be available to you shortly after.
Although Tesla has moved away from the FSD Beta wording and it’s now officially called FSD (Supervised), always remember that this feature requires you to be constantly aware of your surroundings and to monitor the vehicle closely. While FSD will navigate, change lanes, and even take turns, it's imperative to stay attentive and cautious—the system is designed to assist, not replace, the driver.
What If I Already Subscribe
In the previous FSD trial earlier this year, Tesla also gave a free trial to Tesla owners who already subscribe to FSD. This essentially gives you a month of FSD for free. We have confirmed that this trial is functioning the same way, and users who are already paying for FSD are receiving a free month.
If you receive the free FSD trial message in the app, you should see the payment date for FSD skip a month so that you only get charged the next FSD payment after your free month ends.
How to Get the FSD Trial
You don’t need to do anything to get the free FSD trial. Tesla isn’t sending it to everyone at once, but most owners who live in the U.S. or Canada should receive the free 30-day trial soon.

Tesla has released software update 2025.2.6, and while minor updates typically focus on bug fixes, this one introduces a major new feature. With this update, Tesla has activated the in-cabin radar, a sensor that has been included in some vehicles for more than three years but remained unused until now.
Why Not Vision?
Unlike vision-based systems, radar can precisely measure object dimensions and even detect movement behind obstacles by bouncing radio waves off surrounding surfaces. This allows for more accurate and reliable measurements of objects that vision may not even be able to see, such as behind the front seats.
What Tesla Announced
Tesla recently highlighted the 4D radar in the new Model Y, explaining how it will improve passenger safety. Tesla executives stated that the radar would be used to properly classify passengers and improve the way airbags deploy.
Tesla went on to say that in a future update, Tesla will use the in-cabin radar to detect any potential passengers left in the vehicles. Since radar can even pick up on heartbeat and breathing patterns, it can provide a much more accurate method of detecting children left in a vehicle. Tesla talked about how the vehicle will send owners a notification via the Tesla app and enable the HVAC system if it detects a passenger in the vehicle. It’ll even call emergency services if needed.
New Feature in Update 2025.2.6
Tesla has officially named this feature in update 2025.2.6, “First-Row Cabin Sensing Update,” which appears to align with the first portion of what Tesla discussed in the new Model Y video.
In the release notes, Tesla describes the update as:
“The first-row cabin sensing system has been updated to use cabin radar, which is now standard in all new 2025 Model Ys. Your Model Y was built pre-equipped with the necessary hardware, allowing Tesla to also bring this technology to your vehicle.”
For now, it appears that Tesla is using the radar to detect and classify passengers in the front seats. This could eventually replace traditional seat sensors, reducing the number of hardware components and lowering production costs.
Tesla plans to expand the feature later this year, bringing rear-seat passenger detection in Q3 2025. While Tesla talked about the feature for the new Model Y, we expect it to be available for all vehicles with the in-cabin radar.
Supported Models
Although Tesla is vague in their release notes, this feature is being added to all Model Ys that include a cabin radar. Tesla started including the cabin radar in 2022, but its availability may vary by region and model. The Model 3 didn’t receive the cabin radar until it was redesigned in 2024, while all Cybertrucks already include it.
The owner’s manual for the redesigned Model S and Model X doesn’t specifically mention the interior radar, although Greentheonly believes the vehicles also include one, so we’ll have to wait to determine whether those vehicles also receive this new feature.
At this time, the feature appears to be only going out to Model Y vehicles, but we expect it to become available on other supported models soon.
We love to see these kinds of updates. Tesla is increasing the safety of existing and new vehicles through a software update while also making them more affordable to own.
Tesla has updated the Tesla app to version 4.42.0, and this time, it’s more than just bug fixes. The app includes a new service interface, introduces support for the new Model Y, and, for the first time, includes some code for the Robotaxi coming later this year.
This update was released for iOS and should be available on Android within a few days.
Refreshed Model Y 3D Model
First up in the update is the introduction of the 3D model for the refreshed Model Y. Interestingly, while we all know it as Juniper, the file code name inside the update lists the vehicle as “Bayberry.” The Bayberry name was introduced in Tesla app update 4.41.5. Tesla’s internal code names sometimes change as the vehicle evolves - and we’ll continue to refer to it as the refreshed or new Model Y for ease of understanding.

As usual with Tesla’s 3D models in the app, there’s a lot of detail, although it’s not easy to see since you can pinch and zoom the model in the app. The 3D models used in the app are actually the same models that Tesla uses in the vehicle, although sometimes they include different lighting effects, but they’re all highly detailed.
Robotaxi API
Tesla has added a new endpoint in their app for Robotaxi - and it’s the very first Robotaxi or Cybercab-related item we’ve seen in the app. With the Robotaxi fleet launching in June, according to Tesla, it looks like they’re now adding support to the Tesla app.
What the Robotaxi interface is supposed to look like in the future.
Not a Tesla App
The new app API is called “rides_feedback_upload,” which seems pretty explanatory. Tesla will need to gather a lot of information on ride quality and all the little things in between. What better way than to get feedback directly from users?
While Tesla previously released prototype images of what the Robotaxi app will look like, the introduction of this API into the Tesla app leads us to believe that Tesla will utilize the current app for Robotaxi use.
Updated Service Interface
The Updated Service Panel in the Tesla App
Not a Tesla App
Tesla has released an updated UI for the Tesla Service panel, and we have a ton of details on these changes. This new pane displays appointment details more prominently. If you have a service appointment scheduled, you’ll now see a lot more details on the main service screen. The app will now display:
Your current service status
Appointment date and time, which you can now tap on to add the event to your calendar
Address and hours of the service center. You can now also tap on the address to open up the location in your maps app
There’s also a new appointment details screen (the right portion of the image). This screen displays additional details that were previously unavailable, such as your transport type. The app will display whether you’ll get a loaner vehicle, demo vehicle, or something else.
There are a ton of user experience (UX) improvements in this update regarding service, including clearer language, improved UI fixes to images, and more.
Tesla has been making a lot of positive updates to the Service-related sections of the app lately, and we’re happy to see these coming rapid-fire. Tesla Service is now easier to use and understand. In the previous app update, Tesla also added the ability to pull down to update the service screens.
