Tesla adds Driver Monitoring System, DMS to Model 3 and Model Y cars with a cabin camera

By Nuno Cristovao

Tesla Autopilot has always required and will require full driver attention for the foreseeable future. Tesla enforced this by detecting whether torque was being applied to the steering wheel.

Tesla's DMS

Tesla has relied on this method since the introduction of Autopilot, but unfortunately there have been several flaws with it for years.

Since Tesla is looking for a certain amount of force to be applied to the steering wheel, sometimes the car can ask for the driver’s attention even when the driver is attentive and their hands are on the steering wheel. The interval that the car checks for active participation has changed over the years, but with it being somewhere around 30-60 seconds, it can sometimes become an annoyance to drivers.

The second reason that detecting torque on the steering wheel doesn’t work well as a driver monitoring system is that it is easily defeated. There have been numerous devices that mimic the force of hands on the steering wheel and let's face it, it doesn’t lead to anything good for the driver or Tesla.

Tesla's Driver Monitoring System

Yesterday we saw the first vehicles to introduce a true driver monitoring system. For vehicles with a cabin camera, which include all Model 3 and Model Y vehicles, Tesla will be able to turn on their camera-based driver monitoring system (DMS). It appears that the feature is currently limited to the US and only for radar-less cars, but we expect this to change in the future. The release notes for 2021.4.15.11 state that:

Update: With the release of update 2021.32.5, Tesla has started to roll out driver monitoring to vehicles with radar as well. It is also expanding the feature to outside of the US.

The cabin camera above your rearview mirror can now detect and alert driver inattentiveness while Autopilot is engaged. Camera data does not leave the car itself, which means the system cannot save or transmit information unless data shared is enabled. To change your data settings, tap Controls > Safety & Security > Data Sharing on your car's touchscreen.

Much like Tesla implements FSD, the cabin camera will be recording and analyzing the video stream and attempting to detect several objects and driver attributes. Each attribute then gets a probability assigned to it. If the threshold is high enough for any given attribute that Tesla deems as the driver not paying attention, then the car can take additional action from there such as turn off Autopilot, pull over or ask the driver to pay attention.

According to GreenTheOnly on Twitter, the camera will be detecting whether the driver is looking down or to the side and tracking eye movement and detecting other things as well such as whether the driver is wearing sunglasses and how well the camera can see. Although Tesla is looking for a variety of distractions, it looks like they are only currently triggering alerts when the driver is on their phone and not looking at the road.

The first cars have started rolling out with this feature enabled and it hasn't replaced Tesla’s steering wheel torque detection, but is providing another layer of protection. We hope as Tesla expands its capability in the future it may one day replace having your hands on the Tesla wheel completely.

Tesla has also recently rolled out detecting whether there is a driver in the driver’s seat during the use of Autopilot. It’s possible Tesla will create an algorithm with all of these attributes and ultimately decide whether the driver is paying attention or not. This could greatly reduce the amount of times the driver is asked to pay attention when they already are and also increase safety by reminding us when we’re not.

Is Tesla Planning to Add Steam Support to All Vehicles?

By Karan Singh
Not a Tesla App

Yesterday, we reported that Tesla updated their Steam integration on Model S and Model X vehicles. The update was part of their 2024 Holiday Update, but it looks like there may be more to this than a simple update.

Steam, a video game library app, makes it easy for users to buy or launch games on their computers. However, a couple of years ago, Valve, who created Steam, launched their own standalone device, the Steam Deck. The Steam Deck runs a custom OS based on Linux.

Steam Launch

When Tesla launched the redesigned Model S and Model X, Tesla introduced a dedicated gaming GPU with 16GB of RAM and touted the ability to play top-tier PC games in Tesla vehicles.

In 2022, Tesla finally launched the Steam app for the Model S and Model X as part of its 2022 Holiday Update. The Steam app runs Steam OS, the same OS as the Steam Deck in a virtual environment.

However, earlier this year, Tesla stopped including the GPU and Steam (Beta) in their vehicles, and we haven’t seen any updates to the Steam in quite some time. In fact, we thought Tesla was axing their gaming-on-the-go dreams.

SteamOS Update

The Steam app, which is still in Beta, is getting an interesting update for the Model S and Model X vehicles with the discrete GPU.

Those vehicles received an update to SteamOS 3.6 - the same version of SteamOS that runs on the Steam Deck. While nothing has visually changed, there’s a long list of performance optimizations under the hood to get things running smoother.

Comparing Steam Deck to Tesla Vehicles

Let’s take a look at the Steam Deck - according to Valve, its onboard Zen4 CPU and GPU combined push a total of 2 TFlops of data, which is fairly respectable, but much lower than today’s home consoles. The Steam Deck is capable of 720p gaming fairly seamlessly on low-to-medium settings on the go and is also built on the AMD platform.

AMD-equipped Teslas, including the Model 3 and Model Y, are packing an older Zen+ (Zen 1.5) APU (processor with a combined CPU and GPU). AMD claims that the V1000 - the same embedded chip as on AMD Tesla vehicles (YE1807C3T4MFB), brings up to 3.6 TFLops of processing power with it, including 4K encoding and decoding with the integrated GPU on board.

While that’s not enough for 4K gaming or comparable to a full-blown console or desktop GPU, that’s enough raw horsepower for light gaming and is currently more powerful than the Steam Deck.

The Model S and Model X’s GPU brings that up to about 10TFlops of power - comparable to modern consoles like the Xbox Series X at 12 TFlops.

Steam Gaming for All Vehicles?

The fact that Tesla is updating SteamOS even though the feature is no longer available in any new vehicles could indicate that Tesla is not only bringing Steam back to Teslas but that it’s going to play a much bigger role.

While SteamOS is run in a virtual environment on top of Tesla’s own OS, we could see Tesla bring SteamOS to all of its current vehicles, including the Model 3, Model Y, and Cybertruck. Steam in these vehicles would likely support any game that’s capable of running on the Steam Deck.

We think this Steam update, which includes performance improvements and a variety of fixes, has quietly passed under most people’s radars. This could be a very exciting update for those who enjoy gaming, especially for those who love to do it in their Tesla.

Tesla Holiday Update Weather Features: All the Small Details

As part of Tesla’s 2024 Holiday Update, Tesla included two awesome new features - Weather at Destination and the long-awaited Weather Radar Overlay. These two features are big upgrades built upon the weather feature that was added in update 2024.26. The original weather feature added an hourly forecast, as well as the chance of precipitation, UV index, Air Quality Index, and other data.

However, this update also added some smaller weather touches, such as the vehicle alerting you if the weather at the destination will be drastically different from the current weather.

Weather At Destination

When you’re navigating to a destination and viewing the full navigation direction list, the text under the arrival time will show you the expected weather next to your destination. You can also tap this, and the full weather pop-up will show up, showing your destination's full set of weather information.

You can also tap the weather icon at the top of the interface at any time and tap Destination to switch between the weather at your current location and the weather at your destination.

You’re probably considering that the weather at your destination doesn’t matter when you’re three hours away - but that’s all taken into account by the trip planner. It will add in both charge time and travel time and show you the weather at your destination at your expected arrival time.

And if the weather is drastically different or inclement, such as rain or snow, while you’ve got sunshine and rainbows - the weather will be shown above the destination ETA for a few moments before it tucks itself away.

Tesla also recently introduced a new voice command. Asking, “What’s the weather?” or something similar will now bring up Tesla’s weather popup.

One limitation, though—if you’re planning a long road trip that is more than a day of driving, the weather at destination feature won’t be available until you get closer.

Weather Radar Overlay

As part of the improvements to weather, Tesla has also added a radar overlay for precipitation. You can access the new radar overlay by tapping the map and then tapping the weather icon on the right side of the map. It’ll bring up a radar overlay centered on your vehicle. It’ll animate through the radar data over the last 3 hours so that you can see the direction of the storm, but you can also pause it at any point.

You’re able to scroll around in this view and see the weather anywhere, even if you zoom out. It also works while you’re driving, although it can be a little confusing if you’re trying to pay attention to the navigation system. If you like to have Points of Interest enabled on your map, the weather overlay will hide POIs except for Charging POIs.

Requirements / Data

Unfortunately, you’ll need Premium Connectivity for any of the weather features to work, and being on WiFi or using a hotspot will not be enough to get the data to show up. The data, including the weather radar, is provided by The Weather Channel.

As for supported models, weather and weather at destination are available on all vehicles except for the 2012-2020 Model S and Model X. The weather radar has more strict requirements and requires the newer AMD Ryzen-powered infotainment center available on the 2021+ Model S and Model X and more recent Model 3 and Model Y vehicles.
