In our continued series exploring Tesla’s patents, we’re taking a look at how Tesla automates data labeling for FSD. This is Tesla patent WO2024073033A1, which outlines a system that could revolutionize how Tesla trains FSD.
We’ll be approaching this article the same way as others in the past, by breaking it down into easily digestible portions.
Training a sophisticated AI model like FSD requires a tremendous amount of data. But all of that data needs to be labeled - and traditionally, this process has been done manually. Human reviewers have to go in and categorize and tag hundreds of thousands of data points across millions of hours of video.
This isn’t just laborious and rote work, it's time consuming, expensive, and prone to human error. The perfect job to hand off to AI.
Tesla’s Automated Solution
Tesla’s patent introduces a model-agnostic system for automated data labeling. Just like their previous patent on the Universal Translator, this will function for any AI model - but FSD is really what it is for.
The system works by leveraging the vast amounts of data collected by Tesla’s fleet to create a 3D model of the environment, which is then automatically used to label new data.
Three Step Process
This process has three steps, so we’ll look at each individually.
High-Precision Mapping
The system starts by creating a highly accurate 3D map of the environment. This involves fusing data from multiple Tesla vehicles equipped with cameras, radar, and other sensors. The map includes detailed information about roads, lane markings, buildings, trees, and other static objects.
It's like creating a digital twin of the real world, and this is exactly the simulation data that Tesla uses to rapidly test FSD. The system continuously improves its accuracy as it processes more data and also generates better synthetic data to augment the training dataset.
Multi-Trip Reconstruction
To refine the 3D model and capture dynamic elements of the environment, the system analyzes data from multiple trips through the same area. This allows it to identify moving objects, track their trajectories, and understand how they interact with the static environment. This way, you have a dynamic, living 3D world that also captures the ebb and flow of traffic and pedestrians.
Automated Labelling
Once the 3D model is sufficiently detailed, it becomes the key to automated labeling. When a Tesla vehicle encounters a new scene, the system compares the real-time sensor data with the existing 3D model. This allows it to automatically identify and label objects, lane markings, and other relevant features in the new data.
Benefits
There are three simple benefits to this system, which is what makes it so valuable.
It is far more efficient. Automated data labeling drastically reduces the time and resources required to prepare training data for AI models. This accelerates development cycles and allows Tesla to train its AI on much larger datasets.
It is also scalable. This system can handle massive datasets derived from millions of miles of driving data collected by Tesla's fleet. As the fleet grows and collects more data, the 3D models become even more detailed and accurate, further improving the automated labeling process.
Finally, it is accurate. By eliminating human error and bias, automated labeling improves the accuracy and consistency of the labeled data. This leads to more robust and reliable AI models. Of course, human review is still involved, but that’s only to catch and flag errors.
Applications
While this technology has significant implications for FSD, Tesla can use this automated labeling system to train AI models for various tasks.
Object detection and classification: Accurately identifying and categorizing objects in the environment, such as vehicles, pedestrians, traffic signs, and obstacles.
Kinematic analysis: Understanding the motion and behavior of objects, predicting their trajectories, and anticipating potential hazards.
Shape analysis: Recognizing the shapes and structures of objects, even when partially obscured or viewed from different angles.
Occupancy and surface detection: Creating detailed maps of the environment, identifying occupied and free space, and understanding the properties of different surfaces (e.g., road, sidewalk, grass).
These different applications are all used by Tesla - which uses different AI subnets to analyze all these different things before feeding them into the greater model that is FSD, which means things like pedestrians, lane markings, and traffic controls are all labeled on-vehicle.
In a Nutshell
Tesla's automated data labeling system is a game-changer for AI development. By leveraging the power of its fleet and 3D mapping technology, Tesla has created a self-learning system that continuously improves its ability to understand and navigate the world.
Imagine a world where self-driving cars can label and understand the world around them without human help. This patent describes a system that could make that possible. It uses data collected from many Tesla vehicles to create a 3D model of the environment, which is like a virtual copy of the real world.
This 3D model is then used to label new images and sensor data, eliminating most needs for human intervention. The system can recognize objects, lane markings, and other important features, making it easier to train AI models.

Tesla has quietly launched a new monthly subscription service in the United States for windshield protection. This is separate from the recently announced Extended Service Agreement, an extended warranty that is paid for monthly.
This new plan specifically targets one of the most common and costly repairs: windshield damage, which is not covered by the extended warranty.
This new plan is a nice addition for users who prefer peace of mind, but it comes with some very specific and time-sensitive eligibility windows that all new owners should be aware of.
Coverage & Cost
For a flat monthly fee that varies by model, the Windshield Protection Plan provides comprehensive coverage for the front windshield, including the use of Tesla OEM glass and any required Autopilot camera calibrations.
The benefits include:
One free windshield replacement every 12-month period with no deductible
Any additional replacements incur a $100 co-pay per replacement
Unlimited chip and minor crack repairs
Tesla varies the pricing based on your vehicle:
Model 3 / Model Y: $12 per month
Model S: $15 per month
Model X: $23 per month
Who is Eligible and When?
This is the most crucial part to take away here.
You must enroll within 30 days of taking delivery of a new or used Tesla vehicle.
This is a very tight window, so new owners interested in the plan will need to subscribe pretty quickly. However, Tesla does offer alternative ways to get into the program.
Alternative Ways to Join
If you paid for a replacement windshield at Tesla, you also have 30 days to join the program. Likewise, if your vehicle passes a complimentary vehicle inspection, Tesla will also offer you the ability to join the program.
Although the complimentary inspection isn’t available yet, Tesla expects to begin offering the program sometime around July 2025. For now, the plan is only available in the US, similar to the new Extended Service Agreement Subscription. However, Tesla has announced plans to roll it out to other regions shortly, starting with Canada and Mexico.
No Cybertruck Coverage
Just as with the ESA, the Cybertruck is left out. The new Windshield Protection Plan isn’t being offered on the Cybertruck.
This exclusion is particularly important given the high cost of replacing a windshield for the Cybertruck. Out-of-pocket replacement costs exceed $2,300 USD. For now, Cybertruck owners will have to rely on their standard auto insurance for coverage.
How to Subscribe
Enrolling in the Extended Service Agreement or the Windshield Protection plan is handled directly within the Tesla App. If your vehicle is eligible, you’ll be able to navigate to Upgrades > Service Plans > Windshield Protection to review the terms and subscribe.
Once the complimentary inspection is available, you’ll be able to subscribe in person at a Tesla service center as well.
This new plan offers an affordable way for owners to hedge against one of the most common, frustrating, and expensive repair costs, and is expected to be a popular add-on.
Tesla has introduced a new, more flexible and affordable way for owners to get peace of mind after their factory warranty ends. This new service is a monthly subscription that replaces the previous Extended Service Agreement (ESA) in the United States.
The new subscription model makes it more appealing to owners, as it avoids a large upfront payment. This new subscription also offers better coverage terms than before.
Longer Coverage, Better Flexibility
The biggest upgrade in this new format of the ESA is the length of the coverage. The old prepaid ESA was limited to just two years or 25,000 miles beyond the factory warranty, for a total of up to 75,000 miles.
The new monthly program doubles the potential coverage period, offering protection for up to four additional years beyond the factory warranty, or until the vehicle reaches 100,000 miles, whichever comes first. Coming from a basic vehicle warranty of 4 years or 50,000 miles, this is a huge jump up in customer protection.
Pricing & Deductible
The monthly price is simple, but it varies depending on the model. The Model 3 is the most affordable at just $50 per month, while the Model X is the most expensive at $150 per month.
Model 3: $50 / month
Model Y: $60 / month
Model S: $125 / month
Model X: $150 / month
However, Tesla will also charge a $100 deductible for each service visit that covers an included repair, on top of the monthly subscription fee.
Exclusions
The ESA is an exclusionary warranty, meaning it covers the repair or replacement needed to correct a failure of most parts manufactured or supplied by Tesla. However, there are some parts not covered under the ESA, which include:
Issues arising from accidents, modifications, or environmental damage
Essentially, the ESA is designed to cover the components other than the drivetrain. That includes the touchscreen, computers, heat pumps, suspension, or other non-drivetrain electronics that aren’t covered after the 4-year basic warranty.
Tesla vehicles come with an extensive battery and drivetrain warranty that covers these items for up to 8 years. The maximum mileage varies by model. RWD Model 3 and Model Ys are covered for the first 100k miles, while Long Range Model 3s and Ys are covered up to 120k miles. The Model S and Model X are covered for up to 150,000 miles or 8 years.
Eligibility and Sign-Up
Eligibility for the new ESA subscription is pretty clear-cut.
Your vehicle must be within its 4-year / 50,000-mile Basic Vehicle Limited Warranty. Tesla will send customers whose basic warranty is about to expire a notification approximately 3 months before the time-based expiry.
The subscription is not available for leased vehicles or vehicles that were purchased used. Tesla plans to offer eligibility to customers who purchase their vehicle at the end of a lease by the end of 2025, and for used vehicle customers in the near future.
The Cybertruck, due to its relatively newness to the market, doesn’t have access to the ESA quite yet - but it will be coming “in the near future.” For Canada and Mexico in particular, the ESA is not yet available, but Tesla has confirmed plans to bring this subscription to other regions soon.
Subscribing is done through the Tesla App. Tap Upgrades> Service Plans > Extended Service Agreement. Once you review the terms and the monthly fee, you can then hit Subscribe and confirm your payment information.
If the ESA is not visible, your vehicle is not eligible for the subscription.
Payments for the ESA only begin once your original warranty has expired. However, you can sign up at any time, and payments will automatically start when your factory warranty expires.
Other Service Plans
Tesla also offers a Windshield Protection Plan and a Wheel and Tire Protection Plan, if you didn’t already know. Both of these plans are subscription-based and are currently only available in the United States. However, Tesla has indicated that it plans to expand to other regions in the near future.
