Tesla has introduced an innovative feature called 'Driver Drowsiness Warning'. This new safety uses the vehice's internal camera to detect and warn potentially fatigued drivers.

Beyond Autopilot

Tesla's driver's monitoring systems have thus far been limited to Autopilot and FSD use, warning users to pay attention to the road while Autopiot is engaged. However, this is the first time Tesla is monitoring drivers while Autoilot is off. Driver Drowsiness Warning is expected to be Tesla's next active safety feature.

Tracking Metrics

Renowned Tesla hacker @greentheonly shed light on the forthcoming feature back in May. By decompiling Tesla's firmware, he unveiled that Tesla plans to utilize its camera-based monitoring system to gauge signs of driver fatigue. This includes tracking metrics such as the number of yawns and blinks, alongside evaluating driving patterns that are associated with drowsiness.

How Does It Work?

The Driver Drowsiness Warning system is only activated when vehicles have been driving for at least 10 minutes and the vehicle is traveling over 40 mph (65 km/h). Autopilot must also be disengaged. If the system recognizes symptoms of drowsiness, a visual alert flashes on the screen, matched by an audible warning. The notification prompts drivers to consider pulling over for a break before continuing to drive. However, Tesla will not prevent the driver from operating the vehicle.

Drawing data from the cabin camera and studying driving behaviors, Tesla's new feature employs a multifaceted methodology. It observes the driver's facial characteristics, such as yawning and blinking frequencies and driving patterns, such as lane warnings, to discern drowsiness. Once flagged, the alert remains on the screen until the driver is alert or slows down below 40 mph.

Turning Off the Warning

Tesla's new Driver Drowsiness Warning is sort of optional. Although you can disable it in the vehicle's settings by navigating to Controls > Safety > Driver Drowsiness, it is automatically re-enabled at the start of each drive.

Is this the Nag?

For anyone who has driven a Tesla with Full Self Driving enabled, you are well aware of the nag. For those who have not had the pleasure, it's a visual and audible warning to "apply slight pressure to the wheel" or to pay attention to the road. Tesla has considered removal of the nag before but quickly met resistance.

However, this kind of new nag could've played a role in preventing the crash where the FSD system warned the driver to take control 150 times over 45 minutes before the impact with emergency vehicles.

Evolving Monitoring Capabilities

Tesla's journey in driver monitoring has witnessed significant evolution. While initial systems were limited to detecting torque on the steering wheel, advancements post-2021 included the cabin-facing camera to ascertain driver attention. This shift marked Tesla's venture into comprehensive driver observation, ensuring the driver's gaze remains fixed on the road and is devoid of handheld device distractions.

Release Date

The feature's unveiling in Tesla's European owner's manual points to an imminent release. However, the feature doesn't appear to be active yet. Tesla's release notes have made no mention of this significant change so far, but it could be in an upcoming update. When the feature is released, we expect it to be available in select regions. Tesla will typically release a new feature such as this one in specific regions to gather additional data before making it available more widely.

Tesla Issues Physical & OTA Recall for Hardware 4 Computer

By Karan Singh
Not a Tesla App

Tesla has issued a recall for some vehicles due to issues linked to a revision of the Hardware 4 (HW4) computer that was introduced this past November. This recall affects all vehicles with the revised hardware except for the Cybertruck, as it uses a slightly modified version of the HW4 system.

Many vehicle owners have reported a complete failure of their Autopilot computer, which not only leaves the vehicle without FSD and Autopilot but also disables many of the active safety features that make a Tesla what it is.

Let’s take a look at this recall - because the recall is partially physical and partially a software recall.

HW4 Failure

Tesla has identified the failure and flagged it to the U.S. NHTSA (but not Transport Canada or Euro NCAP at the time of publishing) as a recall.

Tesla mentions that the vehicle’s FSD computer circuit board may short circuit, resulting in the loss of the rearview camera image. The recall itself is focused on the rearview camera - as not having a functional rearview camera breaks a Federal Motor Vehicle Safety Standard. However, it does impact more than just the rearview camera.

As previously mentioned, users have experienced the full loss of Autopilot and FSD on these vehicles, as well as reduced traction control and removal of safety features such as automatic emergency braking, collision avoidance assist, and forward collision warnings. 

While the vehicle remains driveable, it is not necessarily a good idea to drive the vehicle with many of these features, especially with the reduced traction control noted by many people. We’ve already noted that while Tesla has been sending tow trucks to pick up some vehicles, it is also prompting owners to drive the vehicle to their service center in some cases.

Remedy

Unlike most of Tesla’s recalls, this one isn’t entirely an OTA recall, owing to the fact that people have already experienced circuit board shorts and are already waiting for replacements.

The software portion of the recall has already been mostly completed for any vehicles with Tesla software update 2024.45.25.3 or greater. However, a significant portion of the tracked fleet remains on update 2024.44.25.2 (approximately 20%), so we recommend updating your HW4 vehicle whenever you receive the notification.

On the hardware side, Tesla is immediately identifying and replacing vehicles that have experienced a circuit board failure. Tesla is also reaching out to customers who have expressed intermittent issues with either Autopilot features, active safety features, or vehicle cameras not displaying correctly in their vehicles. If you have experienced any of these issues in a late 2024 vehicle, we recommend putting in a service ticket with Tesla to ensure that your vehicle isn’t affected by this recall.

Tesla Officially Unveils the 2025 Model Y - New Turn Signal Stalk, Front Camera, New Color, Light Bars and More

By Karan Singh

After a long wait, Tesla has finally launched the refreshed Model Y - the world’s best-selling vehicle - in China. The vehicle is available for pre-order throughout the Asia-Pacific market, so let’s dive into everything new.

Currently, Tesla’s order page expects the first vehicles - the Launch Series - to begin deliveries to customers in May 2025, just about four months away. For now, there are just two variants - the Rear Wheel Drive, and the Long Range, All Wheel Drive model.

Launch Series Edition

Similar to the Foundation Series Cybertrucks, the Launch Series Model Y’s are a limited release and include a set of additional options.

You’ll get an exclusive Launch Series badge on the rear liftgate and doorsill plate. Plus, the Launch Series badging shows up in the puddle lights too. The charging console also has “LAUNCH” as a wordmark on the trim, and the interior comes with an exclusive black vegan suede finish.

Launch Series for the Long Range AWD also comes with Acceleration Boost, the first time Tesla has ever included the feature outside of an “in-app” purchase.

What’s New

There are a lot of new things in the 2025 Model Y, from a new and sharp-looking exterior, an improved interior, and even better specs to round off the whole package. There are even several surprises that we didn’t know about. There’s a lot to like here.

Exterior

Tesla has redesigned the front and rear of the vehicle with iconic new light bars, which they mention increase vehicle aerodynamics, efficiency, and range. Part of this includes redesigned body castings for the Model Y refresh, reducing parts from 70… to just one. That’s fewer gaps, all designed to make an even quieter ride than before. We’re excited to see how all these improvements perform - after all, increasing stiffness is the key to a better ride.

The front bumper camera is also visible - so that’ll be the first for a Tesla vehicle outside of the Cybertruck. Hopefully, they’ll include it in FSD and Actually Smart Summon as well, but right now, at least on the Cybertruck, it’s only used for Autopark or, of course, to use it manually.

Indirect Rear Light Bar

The rear light bar is actually not aimed away from the car - but at it. According to Tesla, it's the first indirect reflective body panel taillight - and it looks cool. Tesla has also redesigned several curves on the car - it looks far more aerodynamic and cuts a sharp figure over the original Model Y. These changes will improve range and performance.

Tesla has also introduced a new color - Glacier Blue - exclusive to the 2025 Model Y Refresh for now. The standard color option is Stealth Grey, while Pearl White Multicoat, Glacier Blue, Quicksilver, and Ultra Red are all available as options.

Tesla has also removed the hitch option from the Model Y Refresh. This is a big change - it was the only non-premium level Tesla vehicle to include a tow hitch. We’re hoping that Tesla does include a tow hitch in versions coming to North America and Europe - as many users do use them. If it is indeed gone, that’ll mean the only vehicles left in the lineup with tow hitches will be the Cybertruck, Model S, and Model X.

Interior

First up - ventilated seats and ambient lighting will be the first two things you see, along with new soft-touch finishes across the interior. Tesla has really hit the mark with the interior of the Model Y Refresh - it looks clean and sharp.

The updated interior still features a 15.4-inch touchscreen - the same size as previous models but also includes an 8” rear touchscreen for all versions of the vehicle, similar to the refreshed Model 3.

Tesla has added improved connectivity to the vehicle - improving the range for the Phone Key, clearer calls, and faster cellular and Wi-Fi connectivity. This is likely a chipset improvement for the infotainment module - and includes a newer version of Bluetooth, as well as support for 5G. We’ll dig into these details once we know more.

The updated speakers are cleverly hidden away inside the trims, and we expect a lot of improvements for Tesla’s already fantastic audio - especially in the Long Range AWD version.

One of the coolest features is power reclining seats - you’ll be able to recline or raise your rear seats at the touch of a button in the rear of the vehicle and potentially in the vehicle menu, too. That’s going to be an amazing convenience feature for families and those moving luggage around.

Turn Signal Stalk

Not a Tesla App

In a surprising move, Tesla says they have listened to customer feedback and added a precision-engineered turn signal stalk. There’s only a single stalk on the left side of the steering wheel while the gear shifter remains on the screen and Autopilot remains as a steering wheel button.

The steering wheel buttons are similar to the Cybertruck, which provide “clicky” feedback. Since the turn signals have moved over to a stalk, Tesla is introducing customizable steering wheel buttons. You’ll likely be able to set them to features like turning on the front or rear cameras, voice commands or other features.

Handling

Just like the Model 3 refresh, Tesla has worked some magic on the suspension, improving vehicle handling and comfort while also offering more responsive steering and an even quieter ride. This includes updated tires, wheels, and a new suspension.

No word yet on Adaptive Suspension - that’ll likely be a hold-out for the Performance variant, which will show up later in 2025.

*Range for the Model Y Refresh is WLTP, while for the 2024 vehicle, it is EPA estimates. WLTP estimates are generally on the higher side owing to geography and temperature in the Asia-Pacific.

There’s a lot to take in right here, spec-wise. The Model Y Refresh AWD is faster than its predecessor and has a considerably longer range. According to Tesla’s spec sheet, it also charges slightly faster - even faster than the current LR RWD with its LFP battery. That’s a great improvement across the board.

The RWD is less of an immediate improvement - but this is a Standard Range RWD - not a Long Range RWD, so the comparison isn’t exactly comparable to the 2024 LR RWD. It seems likely that Tesla will replace the Long Range RWD with the 2025 Standard Range RWD once it arrives in North America and Europe. However, even the RWD has a pretty hefty improvement in the 0-60 section.

When Does It Arrive

Tesla says that it’ll be shipping the Model Y Refresh in just a few short months - customer deliveries of the Launch Series should begin deliveries in May - if you’re in the Asia-Pacific region. For customers in Europe and North America, we’ll probably have to wait a few months before the 2025 Refresh arrives here - likely in the early summer months.

Tesla won’t keep people waiting too long - after all, it's the much-awaited refresh of the world’s best-selling vehicle. We’re super excited to see more of it and hopefully get our hands on it for a test drive in the future.
