Tesla is implementing a new hazard light pattern that improves drivers' attention
Emergency Safety Solutions
Tesla is rolling out a significant safety enhancement through a software update. Teslas, already the safest vehicles on the planet, got a little safer thanks to a small company based in Texas. While this article will highlight the advancement in safety, it will also applaud the work of Emergency Safety Solutions, which dared to challenge the old way of doing things.
Overnight Evolution: The Game Changer
Tesla North America didn't mince words when they announced: "If an airbag is deployed, hazard lights will automatically activate & flash faster to improve visibility." Elon Musk added, "New Tesla safety feature uploaded via over-the-air software update. Your car just got better while you slept."
It got much better thanks to a partnership with Emergency Safety Solutions (ESS), which we spotlighted a year ago. The small company, now just five years old, used a Tesla Model 3 to display its advancements in the hazard lights system, which had remained unchanged for more than 70 years. After numerous studies, the company changed everything about the hazard lights and approached Tesla with its findings.
Chilling Frequency: Every seven minutes, a disabled vehicle is involved in a crash on American roads. The result? An alarming 15,000 injuries or fatalities annually.
Ancient Flaws: The primary culprit behind these startling figures is a hazard light system that hasn't been updated in over seven decades.
The Solution: A frequency shift by adjusting flash frequencies from the sluggish 1.5Hz system to between 4Hz and 6Hz immensely heightens driver alertness. Hertz is a unit of frequency, which equals the number of cycles per second. In this case, the frequency of flashing lights is increased from 1.5 flashes per second, up to 4 - 6 flashes per second.
Real-World Outcomes: When 5Hz flash frequency was tested, drivers reacted a crucial 12 seconds faster. Moreover, they recognized an issue of more than three football fields sooner than the 70-year version. The number of drivers shifting to the safer side of a disabled vehicle also shot up dramatically — from 30% to an impressive 87%.
Emergency Safety Solutions also posted on X: "Great step toward making our roads safer for people in disabled and vulnerable vehicles! We appreciate our partnership with Tesla and applaud this major milestone in our mission to protect drivers when they need it most."
Software Update
Tesla states in their post on X that this update is rolling out now in the U.S. to Model 3/Y vehicles and newer Model S and Xs.
It's not clear whether Tesla means this enhancement is available in update 2023.32, or whether it's in the upcoming 2023.38 update, which is currently in employee testing.
It's more likely that H.E.L.P. is implemented in update 2023.38, but we have yet to receive release notes for vehicles in the U.S., so we'll have to wait and see if this enhancement made it in.
More H.E.L.P. to Come
Keep an eye out for even more safety advancements courtesy of this partnership with ESS and Tesla. The company created the Hazard Enhanced Location Protocol or HELP. Beyond the lightning-fast flashes, HELP seamlessly integrates with in-car and phone navigation systems, giving drivers a heads-up about potential hazards before they become visible. It's like giving your Tesla a sixth sense.
Unfortunately, that will take longer as it would require more automakers to get on board with this new system. However, as we've realized, automakers are following Tesla's leadership on several fronts, and they may also increase road safety and implement the advanced system.
If an airbag is deployed, hazard lights will automatically activate & flash faster to improve visibility
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.
