In Tesla software update 2023.38.6 Tesla is quietly adding two new options that gives owners better control over their privacy. In this update, Tesla is adding the ability to disable remote commands and the option to turn off remote debugging.

The move improves privacy and allows Tesla owners to gain greater control over who can access their vehicles and when.

Limit Remote Commands

Last week, we reported that a user was seeing a new option in FSD Beta 11.4.7.3 that allowed him to disable remote commands. This change allowed him to prevent Tesla from executing commands remotely, such as unlocking or starting the vehicle.

The change appears to have been added through a server-side configuration update, although most users with FSD Beta 11.4.7.3 still lack the new option.

Although giving Tesla the ability to execute commands remotely can be beneficial, such as if you're locked out of your vehicle, this new option gives more privacy conscious owners the ability to limit Tesla's access to their vehicle.

This new option is now also a part of Tesla's latest update, version 2023.38.6. However, it's important to note that this new option only limits Tesla's access to execute commands, and not any other third-parties that may have access to the vehicle through their own services.

Disable Remote Debugging

Owners are now noticing that Tesla has added another privacy-focused option in the 2023.38 update. In this update owners now have access to disable or enable remote debugging of their vehicle. Although it's not completely clear what Tesla considers "debugging," it seems that this new option will limit Tesla's ability to connect to the vehicle remotely to run specific commands or look at vehicle logs.

Privacy Comes First

Both of these new privacy options are enabled by default, but they can be changed by navigating to Controls > Service and looking for the new 'Allow Tesla to Remote Start' and 'Allow Remote Debugging' options at the bottom.

While these new options increase Tesla's transparency and privacy, they can limit Tesla's ability to help owners in certain situations. In most cases, the owners will have access to their vehicle and the ability to temporarily enable these options if they need Tesla's help to start their vehicle or help debug any potential issues.

Tesla vehicles are some of the most advanced vehicles on the market in terms of software and connectivity and this is an important step towards achieving a healthy balance between ensuring customer trust and maintaining the necessary access to deliver the exceptional and cutting-edge experience for which the brand is known.

Tesla Smoking While Supercharging? A Look at What's Actually Happening

By Karan Singh

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 Improves YouTube App With Smoother Playback

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.
