Tesla in introduce Waze-like features and warnings
Fortune
One of Tesla’s latest software updates, FSD Beta 11.4.8.1, which is update 2023.27.12, includes code pointing to several new, unexpected features. According to our favorite Tesla hacker, Green, also known as @greentheonly on X, there will be new Waze-like features, new routing options and a driver “liveliness” system.
Speed Cam and Red Light Awareness
A key highlight of this update is the integration of speed camera and red light cam awareness, functionalities that seem to be inspired by popular navigation apps like Waze. Waze has provided real-time traffic updates, including alerts about speed cameras, traffic congestion, and road hazards. By integrating a similar system, Tesla keeps up with some of the most wanted navigation features. This new feature includes the ability to detect fixed and mobile speed and red light cameras.
The importance of this feature cannot be overstated. Speed and red light cameras are critical in regulating traffic and ensuring safety. However, they can also be a source of anxiety for drivers. Tesla's approach not only assists in compliance with traffic laws but also adds a layer of security and peace of mind.
Tesla is also set to introduce several additional navigation features. One such feature is the "avoid construction on route" option, designed to enhance route efficiency and reduce unexpected delays. Another notable addition is the control over U-turns, allowing drivers to enable or disable U-turn maneuvers in routing options. One much-wanted routing option that owners have been asking for is the ability to use or disable highways. Unfortunately, and somewhat surprising, it doesn’t look like this option is included in this update.
Driver Monitoring Improvements
The update also includes an intriguing development in driver monitoring. The cabin camera now assesses "driver liveliness," a move to ensure the driver's attention is on the road. This feature appears to be aimed at owners who may have tried to trick the system by taping a static photo in front of the camera. It appears that the updated system will check whether the the driver is not only attentive, but also exhibits signs of a human driver.
Release Date
There is significant interest in the availability of these features outside North America, particularly in Europe and Asia. Green has indicated that while these features are currently not user-accessible in this update, its clear Tesla is continuing to develop them and they’ll likely be rolled out in a future update.
While the new routing options may become available worldwide, speed camera locations and red light camera awareness will likely depend on local laws and these features will only be released appropriate.
It’s possible that we’ll see these new features in Tesla’s upcoming holiday update later this month.

Emissions Pooling is an incentive-based program supported by various governments—most notably the European Union—to help automakers meet strict carbon reduction goals under Corporate Average Fuel Economy (CAFE) standards.
CAFE standards mandate that automakers reduce the average CO₂ emissions across their fleet of newly manufactured vehicles. The EU’s 2025 targets are particularly aggressive, and manufacturers risk hefty fines if a sufficient portion of their new vehicles aren’t low- or zero-emission.
Emission Pool
Emissions pooling is a regulatory mechanism that allows automakers to combine their fleet CO₂ emissions to collectively meet environmental targets. Companies with low or zero emissions—like Tesla—can partner with higher-emitting automakers to help reduce their combined average and avoid costly fines.
In practice, this means pool members purchase emissions credits from Tesla, which uses its all-electric lineup to generate surplus credits. These credits help other manufacturers offset their emissions, while Tesla earns a tidy profit.
Tesla has long capitalized on this model, regularly selling emissions credits to strengthen its financials. Now, its European Union emissions pool is expanding again—with Honda and Suzuki joining existing members like Stellantis, Toyota, Ford, Mazda, and Subaru.
Every automaker in Tesla’s emissions pool is effectively buying credits from a company with a 100% zero-emission fleet. In Q4 2024 alone, Tesla earned $692 million from regulatory and emissions credits, making up nearly 30% of its quarterly net income.
That’s a major chunk of profit driven by programs like emissions pooling—and with Honda now onboard, Tesla gains a significant new partner (and revenue stream) in the EU.
Tesla quietly included a cabin radar in its vehicles for several years before recently activating it through software update 2025.2. Tesla now uses the interior radar for several features, and later this year will add additional features that take advantage of the interior radar.
Cabin Radar Features
The first feature Tesla developed that uses the cabin radar is front row cabin sensing. Instead of relying on sensors in the seats to detect occupancy, Tesla now uses the radar to determine where people are sitting in the vehicle. The radar is much more accurate than a seat sensor, so not only will it prevent false positives that occur when placing a heavy object on the passenger seat, but it could also improve reliability by reducing the number of parts in the vehicle.
In future updates, Tesla intends to expand the occupancy sensing to the rear of all of its supported vehicles, which will help improve vehicle safety by correctly deploying airbags as needed on a dynamic basis.
Regular Radar vs 4D Radar
The 4D radar is Tesla’s latest iteration of the radar, which is capable of even more sensing features. While many of these features are still a work in progress and haven’t been enabled, we recently covered what’s coming for the cabin radar. For now, these 4D radars are limited to the Cybertruck and the refreshed Model Y, but Tesla intends to expand the 4D radar to other vehicles as parts become available. Older vehicles include a different part number for the cabin radar, but it’s not clear if or how that will affect upcoming cabin radar features.
Upcoming Cabin Radar Features
In Q3 2025, Tesla intends to add child-presence detection, as well as health-detection for critical emergencies. In short, the radar is a safety-focused addition and will be able to help protect an individual left behind in a vehicle.
In addition to child detection, the radar will also determine passenger sizes to dynamically determine which airbags to deploy, which can help reduce airbag injuries for shorter individuals sitting in the front seats.
The radar can automatically note if a child or baby is left behind in the vehicle and will notify you via the Tesla app immediately. It will also turn on the HVAC system to ensure their safety. In the case of an emergency, the vehicle can also automatically call emergency services in some cases and even report its location.
As a reminder, while Tesla vehicles outside of the United States support eCall, vehicles within the US cannot call 911 unless a phone is connected to the vehicle via Bluetooth. We hope that Tesla looks to add similar capabilities in North America to improve safety capabilities.
Which Vehicles Have Cabin Radars?
Tesla’s more recent lineup of vehicles includes cabin radars, but this isn’t an exact science, and we’ll explain why a bit further below.
Tesla includes the cabin radar on the 2024+ Model 3 and some 2022+ Model Ys. It’s also included on all refresh Model Ys, the Cybertruck and some 2021+ Model S and Model X vehicles, however, the exact hardware version of the cabin radar does differ between models. While there are different hardware versions for the cabin radar, it’s not clear whether all hardware versions will support all features in the future.
To complicate things further, some pre-refresh Model Ys (late 2022+) are already equipped with the cabin radar, while others are receiving a notice from Tesla to come in and have the radar installed. This is due to Tesla using the radar for driver and passenger occupancy sensing.
As such, some older Model Ys and Model 3s may either be equipped with the cabin radar or may receive a notification from Tesla to have it equipped to address the occupancy sensor recall.
Model S and Model X vehicles manufactured from approximately September 2024 should also include the cabin radar sensors, but it’s best to check to be sure. We’ve got some instructions below on how to do just that.
How to Check If You Have a Cabin Radar
There’s actually an easy way to check whether your vehicle has a cabin radar. To do this, you’ll need to enter Tesla’s Service Mode, which is aimed at technicians, but it’s perfectly safe to do so as long as you exit it before driving and don’t change any settings.
If you’re not sure how to access Service Mode, check out our Service Mode guide that will walk you through the process. Once you’re in Service Mode, use the menu on the left to navigate to the Safety & Restraints section and thenchoose Seats.
You’ll be presented with the seats panel that shows passenger occupancy. Between the two front seats, you’ll see a green box below or above the virtual screen. Tap on it and it’ll either say Restraints Control Module (RCM) or Cabin Radar (ICR).
Location of Cabin Radar
Not a Tesla App
On supported vehicles, the cabin radar is located between the two front seats above the rearview mirror.
Future Features
We expect Tesla to continue to develop features that rely on the vehicle’s cabin radar. Dog Mode, for instance, could be turned on automatically if you leave your pooch inside the vehicle and fail to turn on Dog Mode. Tesla can also trigger the rear HVAC fan even when the seat occupancy sensor isn’t triggered, which happens regularly with child seats.
Tesla is also expected to stop including seat sensors in every seat and instead rely on the cabin camera to detect passengers, reducing the cost of each vehicle. As with other Tesla features, new feature ideas on how to leverage the cabin sensor will come later as owners and product owners think of other clever uses for the new hardware.
