Tesla has added two new privacy options in update 2023.38.6
Not a Tesla App
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.

FSD’s insatiable appetite for AI compute is taking shape once again at Giga Texas, where Tesla is building out Cortex 2.0 — its second large-scale GPU supercomputer cluster — on the facility’s north side.
This confirmation comes thanks to the detailed research and findings by Giga Texas drone pilot Joe Tegtmeyer, who shared his findings on X.
For months, there has been some speculation on what this new site would be - new storage, the Optimus production line, preparation for the Cybercab’s unboxed assembly process, and more. Now, thanks to permits filed by Tesla, we know that this new area is destined to become the second supercomputer destined for FSD training.
Cortex 2.0
There are some key details we can unpack from what we’ve learned about Cortex 2.0. The new facility will be on the north side of Giga Texas, opposite Cortex 1.0, which is on the south side. The permits explicitly tie the usage of this expansion to Cortex 2.0, namely through the fact that it is a data center.
This is actually a change from Tesla’s original plans - the northern section was intended to be used as a central campus support facility, with three smaller facilities and water storage tanks. Now, it has been redesignated as Cortex 2.0 and is one large structure.
The permits that have been filed have already been approved and cover the foundations, underground water mains, and building itself. The steel structure is actively being put together on the concrete foundations, and about 50% of the roof decking is already complete, bringing the exterior shell closer to completion.
Fueling FSD’s Brain
The deployment of Cortex 2.0 is the latest in Tesla’s massive and ongoing investment in the computational power required to train FSD. While this primarily covers FSD for cars, this will also eventually apply to Optimus, which is powered by the same AI4 computer and also runs a variant of FSD.
This isn’t Tesla’s first foray into large-scale AI infrastructure and won’t be their last. Alongside Dojo, their home-grown AI supercomputer, Tesla has been partnering closely with Nvidia to ensure they have the GPUs necessary to do all the hard work. Cortex 2.0 is the next iteration, and once it's fully online, we can expect that Tesla’s work on FSD will accelerate even further.
Especially since Elon is planning something truly outrageous once again:
Been thinking about the fastest way to bring a terawatt of compute online.
That is roughly equivalent to all electrical power produced in America today.
With European Tesla owners eagerly awaiting any news on FSD in Europe, we’ve seen Tesla tease FSD, and also point out exactly what the barrier has been - regulatory approval. Now, following the latest meeting of UNECE, new regulatory amendments are set to unlock “System-Initiated Maneuvers” (SIM) on highways across participating European nations.
This development, highlighted by Kees Roelandschap on X, notes that the latest documents from the United Nations Economic Commission for Europe (UNECE) center on amendments to UNECE regulation 171. These changes were formally adopted into UNECE during the WP29 World Forum in March 2025.
Now, the amendment that will enable SIM will come into force on September 26, 2025. This six-month period after approval is standard UNECE procedure and allows objections from party states that would halt the implementation. Objections to UNECE amendments are genuinely rare, with 95% of amendments passing without objection once the World Forum adopts them.
What This Means for FSD in Europe
System-initiated maneuvers will allow your Tesla to perform actions autonomously, such as changing lanes on a highway, while the driver remains fully responsible for supervision. This is a substantial step up from current regulatory standards that only allow for suggested maneuvers or require explicit driver initiation for every automated maneuver.
This inches towards the more normal “hands-off, eyes-on” approach that Tesla has taken with FSD Supervised in North America and China. This regulatory change will help to provide the legal frameworks needed to deploy more advanced autonomy capabilities in Europe, at least matching what’s available on highways in North America.
The UNECE regulation will apply to all countries that adopt its standards, including the European Union, Japan, and South Korea - unless they specifically block it. This is a relatively positive development, but there are some hiccups.
This regulation only allows for system-initiated maneuvers on highways, not low-speed roadways. That means the city streets portion of FSD’s capabilities - including handling ‘Start FSD from Park` and reaching your destination’s parking spot - still won’t be available in Europe.
In addition, the UNECE framework has stricter requirements for driver monitoring and attentiveness - which means that some nags, including the dreaded wheel nag, are likely to remain a key portion of the experience.
Progress on autonomous driving regulations in Europe has been fraught with indecision and caution, which has been a source of frustration for many who are watching the everyday progress of FSD in North America, and more recently, in China. Even with individual countries recently approving testing of FSD on public roads, harmonized UNECE regulations are the key to wider, consistent deployment, which will allow everyday customers to use it as well.
While the path to full parity with North America may be long and involve even more regulatory machinations, the upcoming implementation of System-Initiated Maneuvers is a big step forward for Tesla owners in Europe. It is a key piece of the puzzle that will help Tesla bring some more features of FSD to Europe, assuming the September timeline holds.
