Tesla has been making steady progress on adding the second of FSD’s “senses” — hearing. Since some FSD updates in late 2024, Tesla has been collecting audio input to help FSD recognize and respond to emergency vehicle sirens. Tesla’s VP of AI, Ashok Elluswamy, previously confirmed that improved handling of emergency vehicles would be coming to a future FSD update.
Now, it looks like Tesla is also introducing a feature to alert drivers when the vehicle detects an emergency vehicle. This change was found by @greentheonly in a production version of update 2025.8, which means that it may not be long before it’s enabled for everyone.
Emergency Siren Detection
In a future update, Tesla will enable the vehicle to alert the driver whenever it detects an emergency vehicle, either through sirens or visually. This is assuming the owner has given the vehicle permission to use the internal microphone. While the new Model Y features multiple internal microphones for better noise isolation, most Teslas only feature a single internal microphone, which is used for features such as voice commands and talking through Bluetooth.
Since the vehicle can see in all directions and is actively paying attention, it will likely detect an emergency vehicle even before the driver, so this is much more than a feature for FSD.
According to Green, Tesla included text in the vehicle software that describes the new emergency vehicle detection as:
“Automatically detects and alerts the driver to nearby sirens, helping you or Autopilot recognize and yield to approaching emergency vehicles. When a siren is detected, the media volume lowers, and an alert appears on the display. Sound detection data stays within the car and is not saved or transmitted unless data sharing is enabled.”
While on FSD, the in-vehicle microphone can help to detect and allow the vehicle to yield to approaching emergency vehicles. In addition, whether you’re using FSD or not, your media volume will be lowered, and an alert will be displayed on your vehicle’s display.
We’re not exactly sure what this alert will look like, but it could look similar to today’s “Keep your eyes on the road” alert, which displays over the center of the display with a blue hue over the screen to catch your attention.
This is an eye-catching alert, and in combination with the media volume being lowered, this should help to grab the attention of a driver in a safe and unobtrusive way.
We love these types of updates that not only improve FSD but also improve safety when drivers don’t have Autopilot enabled.
While Tesla hasn’t enabled this feature just yet, we should expect it soon since it lies dormant in update 2025.8. It could be enabled through a server-side configuration or in Tesla’s upcoming 2025 Spring Update.

Tesla’s Safety Score is used to help determine an owner’s insurance premiums under Tesla Insurance. It attempts to evaluate how safely the vehicle is driven by taking into account several metrics such as harsh braking, turning too fast, and speeding.
Tesla has continuously improved its Safety Score program by adding new metrics or improving existing ones. Tesla is notably transparent about the specific factors that contribute to your Safety Score and, by extension, how insurance premiums are calculated.
With the launch of Safety Score V2.2, Tesla has introduced updates to how Excessive Speeding is factored into your score and removed the controversial Forward Collision Warnings (FCW).
While excessive speeding has been part of the scoring system since March 2024, it has primarily contributed to Tesla’s internal calculations for premium generation. The latest version improves how Tesla determines speeding and its weight into the Safety Score.
Improved Excessive Speeding
The latest version of Safety Score now measures Excessive Speeding as a proportion of the time you spend driving over 85 mph, or when you’re speeding relative to the vehicles in front of you.
This could affect how your score is impacted while overtaking slower drivers—we’ll have to wait and see how this plays out for Tesla Insurance users, and whether rates will rise, fall, or stay steady in the coming months.
Forward Collision Warning
While Tesla didn’t call out changes to Forward Collision Warnings in its Safety Score v2.2 update, it appears that Tesla is no longer using FCWs as a metric in Safety Score, at least in some regions.
Tesla’s Forward Collision Warnings are a helpful feature in Tesla vehicles since they can alert drivers when a vehicle stops suddenly in front of them. However, they can sometimes have false positives, which isn’t a huge deal… unless they’re affecting your insurance premium. While FCWs have been included in Tesla’s Safety Score since its inception, it has often been a controversial metric due to false positives.
With the release of Safety Score v2.2, Tesla has now removed FCWs as part of the Safety Score, and drivers will no longer be penalized when a vehicle stops suddenly in front of them. However, Unsafe Following, an existing Safety Score metric that is defined as “proportion of following time spent at an unsafe following distance,” is still a part of Tesla’s Safety Score.
According to Tesla, this update is designed to offer a more accurate reflection of future collision risk, using insights from over 23 billion miles of real-world driving data. New Safety Scores will begin to reflect these changes as the update rolls out. However, any impact on premiums won’t take effect until next month—so your current premium is safe for now.
It’s worth noting that in California, Safety Score doesn’t affect your insurance rate at all. In those cases, Tesla includes it strictly for educational purposes. But in states where it does apply, it will directly influence what you pay.
Due to constant improvements involving real-world data and billions of miles, Tesla’s Safety Score is a unique and fairly accurate way of assessing safe driving. Unlike traditional insurers—some of which rely on basic smartphone acceleration data—Tesla is able to calculate your score based on nuanced, vehicle-level data and real-time driving conditions. While it isn’t perfect, it gives a clear edge in measuring how you actually drive.
We’re still hoping to see Tesla Insurance expand to more states. Progress has slowed recently, even after the company brought on a former GEICO executive whose main mission is to broaden the program’s reach.
Tesla has just opened up their Early Access Program, which we found out about just a few days ago - to FSD owners and subscribers in the United States. This new Early Access Program will offer regular owners the ability to get early FSD updates before they get widely released.
Early Access
Tesla has begun to slowly roll out a pop-up (and button) in the Tesla app, offering users the ability to enroll in the FSD (Supervised) Early Access Program in the United States. This update is rolling out slowly, so don’t be surprised if you don’t have it yet.
For now, this program appears to be limited to the United States. Users in Canada and Mexico, even those with existing Early Access, have not yet received an invite to the program.
Once you join the Early Access Program, at the very bottom of your app, where your VIN and software version normally appear, you’ll see a new “Early Access” link. Tapping this will show your status as a member of the Early Access program and also offers you the opportunity to leave the program if so desired.

How to Get In?
To be offered the program, you must own an AI4/Hardware 4 vehicle with FSD, either purchased or actively subscribed. Unfortunately, HW3 owners are not receiving this right now.
A pop-up will be displayed in your Tesla app once you get selected to join the program. If you dismiss the pop-up in a hurry, don’t worry. The ability to join Early Access stays as in the image below, and you can join the program at any time.
Ending your subscription while part of Early Access means your vehicle will be removed from the program.

Privacy
In exchange for receiving early builds of FSD, Tesla will increase the amount of data, video, and audio gathered from your vehicle, and the data will be VIN-associated, meaning less privacy and anonymity for users.
Any software updates or release notes you receive, both in-vehicle and in-app, will be watermarked with your vehicle's VIN. Tesla has been watermarking employee release notes since June of 2024 to reduce leaks, and this new Early Access program appears to follow a similar format, even though it is more widespread.

Cautions
Of course, earlier FSD builds are usually less stable and potentially less safe than wide release, so it’s important to remain more vigilant during FSD’s use. If anyone else uses the vehicle, make sure they’re also aware of the situation.
On the flip side, this is really exciting for many Tesla owners. Tesla’s Early Access program has normally been limited to employees and influencers, so it’s awesome to see regular owners getting an opportunity to get in on all the fun of testing out Tesla’s latest FSD functionality.
This new Early Access program could also mean that Tesla has a new level of confidence in future builds, where it’s now willing to make them available to more users. It could also have to do with Tesla’s FSD Unsupervised ambitions, where they may need more data than was already collected in order to successfully launch their Robotaxi this June.
