Tesla will now leverage its fleet of vehicles to help locate rough road segments or non-paved roads.
Although the entire fleet will be contributing, the first vehicles to take advantage of this information will be Tesla’s Model X and Model S vehicles with an adaptive air suspension.
Many Tesla owners have requested that their vehicles learn and adapt to rough roads.
CEO Elon Musk has stated that adaptive air suspension will remain a luxury feature and will stay exclusive to the Model S and Model X, although it's possible other vehicles in the future can take advantage of knowing the location of rough road segments by either slowing down or avoiding potholes.
In November 2020, @JohnEG78 tweeted to Musk stating, “I would like voice commands for air suspension ride height.”
Musk responded, “Ok. Overall air suspension height & dampening algorithm is getting a lot of attention. Will be linked to FSD, so [it] acts automatically.”
Ok. Overall air suspension height & damping algorithm is getting a lot of attention. Will be linked to FSD, so acts automatically.
Update 2022.20 has just started going out to select vehicles and one of the key features in the update is "Tesla Adaptive Suspension."
This feature will let your Tesla with an adaptive suspension automatically lower or raise depending on the type of road. So if you're driving and encounter a gravel or dirt road your vehicle will now automatically adjust its suspension for a smoother ride.
As Tesla ramps up their FSD rollout, the amount of real-world data that Tesla has collected is most likely more than any other automotive company.
Tesla can use this data gathered by the Tesla fleet to automatically adjust the ride height.
If more data is needed or something is inaccurate, a button on the screen or voice command would be a nice addition to report it to Tesla, similar to Tesla's FSD Beta report button.
While we don't have pothole detection and avoidance just yet this could be the start of such a feature.
“Tesla Adaptive Suspension will now adjust ride height for an upcoming rough road section. This adjustment may occur at various locations, subject to availability, as the vehicle downloads rough road map data generated by Tesla cars. The instrument cluster will continue to indicate when the suspension is raised for comfort. To enable this feature, tap Controls > Suspension > Adaptive Suspension Damping, and select the Comfort or Auto setting.”
While potholes may be more difficult for the vehicle to detect, having a built-in system similar to Waze where users can report where the pothole is could be useful. With Waze, users can report a number of issues on the road, including police presence, objects on the road, construction, accidents, and more.
If a pothole is repaired, Tesla could utilize indicators that compare the amount of times the pothole is being reported by the driver or vehicle to before it was repaired. If there are no reports of that pothole in the road anymore, Tesla’s AI could mark that pothole as repaired and remove it from the notification system or adaptive air suspension.

Winter is here, and temperatures are dropping, so one of the most common Tesla questions is about to resurface.
If you’ve landed here after frantically searching about “smoke” coming from your Tesla while Supercharging, take a deep breath—it’s completely normal.
Tesla Smoking While Charging
If you’re Supercharging in freezing weather—even with preconditioning—you might notice steam rising from your Tesla. But rest assured, your car isn’t smoking.
Your Tesla’s heat pump is hard at work warming both the cabin and battery to keep you comfortable and ensure optimal charging temperatures. Over time, condensation and ice build-up in the heat exchanger coils.
Why Does It Happen?
When you reach a Supercharger with your vehicle, the heat pump is still running hot, but without the cold air from driving to keep the heat exchanger coils cool, the ice and condensation quickly start to evaporate—creating what looks like smoke.
Since this typically happens near the front of the vehicle, where a car would traditionally have an engine, new vehicle owners can be startled by the discovery. However, rest assured that it’s just water vapor and it’s completely normal in cold weather.
In fact, this behavior can be experienced in any EV with a heat pump in cold climates. So, if you saw steam coming out of your vehicle and panicked, don’t worry—you’re not alone.
Now that you know what’s happening, go ahead and Supercharge with confidence.
Tesla made a lot of improvements in the 2024 Holiday Update, including more than 15 undocumented improvements that were included in the release. One of these was a stealthy performance improvement to the YouTube app.
Several people have mentioned they’ve seen improved performance on YouTube since this year’s Holiday Update - and there’s an interesting reason why.
YouTube Improvements
The improved YouTube performance in Tesla vehicles comes from an unexpected source—Tesla actually rolled back support for YouTube’s newer AV1 video encoding. Instead, vehicles now default to the older VP9 encoding standard.
While AV1 is highly efficient in terms of bandwidth, it requires considerably more processing power to decode and display videos. VP9, on the other hand, is less computationally demanding but uses more bandwidth to achieve the same video quality. This trade-off means smoother playback and better overall performance, even if it comes at the cost of slightly higher data usage.
Intel Inside
The VP9 video codec that the YouTube app is now using is much easier to decode, making it less taxing on the vehicle’s processor. This change is particularly beneficial for Tesla vehicles with Intel processors, which previously struggled to stream video at just 720p. When using AV1, these vehicles often experienced stuttering, sometimes forcing the YouTube app to automatically downgrade playback to 480p.
With this update, Intel-based Teslas should now be able to stream at 1080p smoothly. Streaming at 1440p is also possible, although occasional stutters still occur as the system keeps up with the decoding process.
Intel-based vehicles are the big winners with this change, but this appears to affect AMD Ryzen-based infotainment units as well, providing even smoother playback.
Chromium Web App
Tesla’s Theater apps aren’t native applications; instead, they run as chromeless web apps, leveraging the open-source browser built into Teslas known as Chromium (the open-source version of Chrome). Although this works quite well, there is a severe limitation - Chromium hardware acceleration isn’t supported on Linux, the operating system Tesla uses for their OS.
As a result, Tesla vehicles rely on software decoding instead of hardware decoding, which would otherwise handle video playback far more efficiently. A potential solution could be for Tesla to transition away from Chromium-based web apps in favor of a Mozilla Firefox-based browser, as Firefox does support hardware acceleration on Linux. This switch could also open the door to better streaming performance and the possibility of expanding Tesla’s in-car entertainment options.
However, Tesla’s choice of Chromium likely stems from Digital Rights Management (DRM) requirements for streaming services like Disney+ and Netflix, which rely on DRM-enabled playback. Firefox on Linux has had inconsistent support for DRM due to codec availability and variations in operating system versions.
We’re hopeful that Tesla will either adopt Firefox or develop a fully native application to improve video streaming, rather than continuing with the current web-based Tesla Theater. This shift could also pave the way for additional in-car applications built on Tesla’s native Linux environment—perhaps even reviving the long-rumored Tesla App Store.
Regardless, this update is a welcome improvement, particularly for YouTube, which remains one of the most widely used Theater Mode apps due to its accessibility, free content, and mix of short and long-form videos. It remains to be seen whether similar improvements are made for Netflix, Disney+, or other streaming platforms.
If you’ve noticed improved performance in Theater Mode, now you know why.
