Tesla has started rolling out FSD v12 to employees
Not a Tesla App
Elon Musk announced earlier this month that Tesla's Full Self-Driving (FSD) v12 would be released in two weeks. The usual timeframe reference Musk is famous for was met with skepticism. However, it seems that Tesla is right on track with its rollout.
We have learned through a trusted source that FSD v12 has started rolling out internally with Tesla update 2023.38.10.
Update: Musk has responded to our article on X, confirming that Tesla has indeed starting rolling out FSD v12 to employees.
FSD v12 is the update that is expected to remove "beta" from the title. The initial rollout to employees appears more limited in scale than previous updates. Considering the magnitude of the changes in this version, it makes sense to start slow.
Public Release
The timing of this internal release is close to two major Tesla events. The Cybertruck delivery event is just a few days away. Many eyes will be on the company during the event, allowing Tesla to possibly show the world its latest breakthrough. Alternatively, the highly anticipated holiday update, often regarded as the best update of the year, is expected to be released by 'Santa Musk' in the coming weeks, potentially featuring v12 as a significant addition.
Newer Features
The latest public FSD build, v11.4.7.3, is Tesla update 2023.27.7. This FSD build is several revisions behind the latest production builds, so it's nice to see that v12 will bring FSD beta testers back up to speed with some of the latest Tesla features such as Predictive Charger Availability, Faster Hazard Lights After a Crash, and other features included in updates 2023.32 and 2023.38.
As for FSD improvements, we haven't had a chance to see the release notes for FSD v12 yet. However, now that it has started going out to employees, it shouldn't be long before we find out all the FSD improvements included in this milestone release.
FSD v12: A Leap Forward with Neural Net Use
A significant change in v12 is eliminating over 300,000 lines of code previously governing FSD functions that controlled the vehicle, replaced by further reliance on neural networks. This transition means the system reduces its dependency on hard-coded programming. Instead, FSD v12 is using neural networks to control steering, acceleration, and braking for the first time. Up until now, neural networks have been limited to detecting objects and determining their attributes, but v12 will be the first time Tesla starts using neural networks for vehicle control.
The FSD v12 represents a significant leap in Tesla's FSD technology. Musk has described it as an "end-to-end AI", employing a "photon in, controls out" approach akin to human optical processing. This analogy underscores Tesla's ambition to replicate human-like decision-making capabilities in its vehicles.
Labeled as a "Baby AGI" (Artificial General Intelligence), the system is designed to perceive and understand the complexities of the real world. This philosophical and technological shift in AI-driven autonomy was vividly showcased during a live-streamed drive by Musk through Palo Alto, where the Model S demonstrated smooth and almost flawless navigation through various real-world scenarios, including construction zones, roundabouts, and traffic. That was three months ago; imagine how much the system has learned in 90 days.
Looking Forward: The Future of Tesla's AI Endeavors
The rollout of FSD v12 marks a critical point in Tesla's journey in AI and autonomous driving. It's not just about technological prowess but also about aligning AI with nuanced human behavior. With Musk's continued focus on AI, which is evident across his ventures, Tesla remains a crucial player in the EV market and the broader AI revolution.
As we await further details on the public release of FSD v12 and its potential showcase at the Cybertruck event, it's clear that Tesla is moving closer to a future where cars are not just self-driving but are also intelligent and responsive to the complexities of the real world.

Your Tesla is packed with features designed to improve your comfort and safety, and Cabin Overheat Protection (COP) is a prime example. While all the materials and equipment in your car are built to withstand the summer heat, this feature prevents the interior from reaching excessively high temperatures when parked.
But what does it do, how does it work, and when should you really use it? Let’s dive in.
What is Cabin Overheat Protection?
Cabin Overheat Protection is a climate control feature that activates automatically after you’ve left your vehicle. Its primary goal is to keep the interior cabin temperature from soaring on hot days, and helping to keep the surfaces humans touch most often - like the seats, steering wheel, and screen- at a more manageable temperature.
You can also use Cabin Overheat Protection to protect temperature-sensitive items from excessive temperatures; however, its primary goal is to prevent the cabin from becoming excessively hot.
For moderate durations, Cabin Overheat Protection can actually reduce the amount of energy spent cooling your vehicle, as it’s more efficient to maintain a temperature rather than letting cooling it down from 130ºF. However, it most cases, Cabin Overheat Protection will use additional energy.
It is important to note what Cabin Overheat Protection is not. It isn’t designed to protect people or pets. For that, you’ll want to use Tesla’s dedicated “Dog Mode” or “Keep Climate On” features, which offer more robust control over the internal temperature. You can read a comparison of the major climate features here.
Enable Cabin Overheat Protection
Tesla offers several options for cabin overheat protection, allowing you to choose when and how it operates. You can enable it in your vehicle or through the Tesla app:
In the Vehicle: Navigate to Controls > Safety > Cabin Overheat Protection.
Via the Tesla App: Go to the Climate, swipe up, and toggle Cabin Overheat Protection.
Cabin Overheat Protection Settings
When enabling COP, you can pick from three settings:
Off: The system is completely disabled and will not activate when the vehicle is parked. This is the default option.
No A/C: If the interior temperature exceeds your set threshold (see below), your vehicle will only use the HVAC fan to circulate outside air through the cabin. This helps cool the vehicle since outside air is often cooler than the inside, which can easily reach 130ºF or higher. This is our recommended setting, as it helps prevent the cabin from getting too hot in most situations and uses minimal energy.
On: If the interior temperature exceeds your set threshold, the system will use both the fan and the air conditioning to actively cool the cabin down to and maintain it below that threshold. This is the most effective cooling option, but it also uses a significant amount of energy.
You can also set a Temperature Threshold for activating Cabin Overheat Protection. Tesla provides three options: 90°F (30°C), 95°F (35°C), or 100°F (40°C). Cabin Overheat Protection will attempt to maintain your vehicle at the threshold while it is active.
Battery Drain
The main reason you might choose to leave Cabin Overheat Protection off is its energy impact, which will not only increase your costs but also reduce your vehicle’s range. Ultimately, this feature keeps your vehicle’s HVAC system—or at least its fans—running to help cool the cabin.
While the No A/C mode consumes minimal energy, the On mode (which uses air conditioning) will noticeably drain the battery, particularly on hot days when the system works harder to maintain the set temperature.
The amount of energy COP uses will vary greatly based on your selected activation temperature, the exterior temperature, and whether your vehicle is parked in the sun. However, in general, the energy impact will be minimal if COP is set to No A/C, and significant if it’s set to On.
As a reminder, Cabin Overheat Protection will automatically shut off after 12 hours of operation or if the vehicle’s state of charge falls below 20%. COP and several other Tesla features will increase the cost of using your vehicle. We recently reviewed all Tesla features that continue to use power while your vehicle is parked.
Is Cabin Overheat Protection Necessary?
This is a common question, and the answer is no, Cabin Overheat Protection is not essential. Tesla vehicles, including their interior components, are designed and tested to withstand the typical automotive temperature cycles, including both hot and cold. While keeping the cabin cooler could potentially provide some marginal benefit in preventing the leather or other surfaces from degrading, the primary purpose is for the comfort of the occupants when they return.
What About Extreme Cold?
We’ve talked about heat, but what about extreme cold? Cabin Overheat Protection, as the name implies, deals with heat and will not prevent your vehicle from getting too cold. For cold weather, your Tesla has different mechanisms.
Your vehicle will automatically use energy to keep its high-voltage battery within a safe temperature range in extreme cold, whether or not you’re in the car. This helps protect the battery’s health and ensures you’ll have a minimal level of performance even if you enter the vehicle without preconditioning.
For optimal comfort in cold weather, preconditioning your vehicle will warm up the cabin and battery for improved performance.
Cabin Overheat Protection is a valuable feature that improves the comfort of your Tesla, particularly during hot weather. However, it’s not designed to improve the lifespan of your vehicle's interior, and it should not be used for people or pets (use Keep Climate or Dog Mode for those situations).
If you're parked in extreme heat and have sensitive items in the car, this could be an ideal use case. Use Keep Climate if you need to keep the items below 80°F, or Cabin Overheat Protection if you’re just looking to protect them from excessive temperatures.
Tesla’s recent focus on expanding and vertically integrating its battery production is beginning to take global steps, starting with a battery recycling and service center in South Australia. In Marion, a suburb of Adelaide, the council recently voted in favor of a proposal that would see contaminated public land developed and leased to Tesla.
The move promises local jobs and environmental remediation but has garnered a lot of public debate focused on Elon’s moves outside his role as CEO.
The proposal involves a site that’s currently unusable for recreation due to chemical contamination. A local developer plans to acquire and remediate the land, constructing a new facility specifically for Tesla. This site would reportedly serve two purposes: recycling old lithium-ion batteries and serving as a Tesla Service Center.
Tesla’s Commitment to Recycling
Tesla recently announced its intention to ramp up its battery recycling and repurposing efforts. During the Q1 2025 Earnings Call, Tesla’s executives highlighted substantial progress. Tesla had recycled enough materials in Q1 2025 to build approximately 21,000 Model Y RWD vehicles, representing a 136% year-over-year increase from Q1 2024.
Dedicated regional hubs like this one would be a logical next step in expanding the recycling loop and furthering Tesla’s vertical integration while also reducing its reliance on new materials. In addition, local sources also mentioned that Tesla could be repurposing older lithium-ion batteries for other purposes, including their inclusion in stationary battery storage systems like Powerwall or Megapack.
Of course, the facility also has major benefits for the local community, including creating around 100 local jobs, as well as injecting approximately $56 million into the local economy. Further, developing the contaminated land as a renewable facility is one of the safest ways to use the land that’s been sealed off from the public for nearly a decade.
Elon’s Image
The proposal isn’t without its critics. Local opposition was voiced during community consultations, with most of the negative sentiment directed towards Elon rather than the facility itself. Despite these complaints, the local council elected to proceed, arguing that tangible economic and environmental benefits far outweigh any perceived geopolitical or symbolic harm that shutting down the project could cause.
With the council’s endorsement on record, the proposal now moves to the South Australian state government for approvals regarding the change in land classification.
