Tesla Reveals How It Tests FSD - A Series of Videos

Not a Tesla App

Tesla has published a 16-post series covering a wide range of unique scenarios against which the company tests each FSD release. Tesla’s VP of AI, Ashok Elluswamy, also provided some additional context, which we’ll cover below.

These scenarios could be difficult for a regular driver to respond to and are a good demonstration of FSD’s capabilities. Let’s take a look at all the different scenarios that Tesla regularly tests against. According to Ashok, these tests are only one of 10 ways Tesla validates their software. These tests were done against FSD v12.5.6.3, the HW4 build that’s on approximately 20% of the fleet.

We’ve embedded each video below and also provided some additional information.

1. Reverse Cut-in (Occluded)

Every FSD release is rigorously tested, including rare and adversarial scenarios on closed courses — Here's 16 examples:

1. Reverse Cut-in (Occluded) pic.twitter.com/VWBKDgVuUc

This first test is for a car reversing out of a parking space, while occluded (vision blocked) by another car or obstacle. In the test, the Model Y notices the incoming car and then brakes with space left over.

2. Peeking (Occluded)

In this video, it's hard to even spot the car on the right that’s “peeking” forward—it's occluded by bushes on the side of the road. FSD notices and stops in time to let the other vehicle safely pass.

3. Left Turn Cut-in

An incoming vehicle that takes a left turn to enter the same lane of travel as FSD - spotted, stopped, and then continuing smoothly. In the second shot, you can see FSD left a considerable amount of space to let the vehicle cut in.

4. Parallel Cut-in (Occluded)

This is honestly one of the most common scenarios on a highway - someone cuts in while obscured into your lane of travel. Once again, FSD does its thing with plenty of space to spare.

5. Yield for Oncoming During Overtake

FSD’s path planner plans an overtake around a stationary vehicle here, sees the oncoming traffic, and politely waits its turn to continue. This is another everyday scenario, especially on urban and suburban streets.

6. Stop Sign Right-of-Way Violator

There are a surprising number of people who don’t know how stop signs work. However, FSD does know how they work and also knows what to do if others act unpredictably. This is one of the best demonstrations of FSD’s capability to react quickly and effectively to unpredictable behavior on the roads.

7. Door Opening During Overtake

Another overtake scenario, but this time the vehicle being overtaken throws open its door into traffic. Not necessarily the wisest of moves, but humans are unpredictable. Good to see Tesla working to save its vehicles from both hitting the door or having the door hit with its new Blind Spot Monitoring While Parked feature.

8. Right Turn Harsh Braking

This scenario is another common one - someone is taking a right turn, and you expect them to complete the turn, but instead, they slam on the brakes. Here, you can see the vehicle’s Forward Collision Warning goes off due to the sudden reduction of distance between the Tesla and the vehicle in front of it. FSD still manages to brake in time before Automatic Emergency Braking kicks in.

9. Left Turn Across Path

This one is pretty clean-cut - someone takes a left turn even though you’re on your way through the intersection. This particular accident is one of the most common - 53% of cross-path accidents involve a left turn through an intersection where a side impact will be lethal. FSD can make a big difference - over 8,000 people die in North America alone in this particular scenario.

10. Cut-Out to Static Cone

Here, FSD smoothly reacts to an object on the road as the vehicle ahead dodges it. We’d love to see this scenario done with different types of objects or debris, as this is another common item - especially with roadkill on country roads. A good demo of FSD’s collision avoidance maneuvers too!

11. Dynamic Debris (Dropped Cone)

Taking it one step further, FSD successfully notices, slows down, stops itself from hitting the bouncing cone, and then makes it around safely. If you’ve ever seen someone strap something down in the bed of a pickup and forget to say “This ain’t going anywhere” - this is that exact scenario.

12. U-Turn Cut-in (Occluded)

— Tesla AI (@Tesla_AI) November 24, 2024

Another high-speed occluded cut-in, this time for a vehicle making a U-Turn from an oddly shaped intersection. FSD started braking the moment the first couple pixels of the Model Y were beyond the bush occluding vision. With a human’s reaction time, this would have resulted in a T-bone.

Ashok Elluswamy mentioned that this is possible because of low latency and high intelligence - combined together, it enables FSD to make a threat assessment and decide what to do, very quickly. It also considers the potential of a rear-end collision - and there is collision avoidance baked into that decision-making.

13. High-Speed Cut-out to Stationary Vehicle

Similar to the cone cut-out, this one happens at 73mph (117km/h)! FSD sees the car dodging, notices there’s an obstacle, and moves out of the way without dropping speed.

14. High-Speed Harsh Braking

— Tesla AI (@Tesla_AI) November 24, 2024

Another common scenario - in fact, the number one reason why pileups occur on highways is the harsh, sudden braking of vehicles in front. FSD once again notices and comes to a safe stop here.

15. High-Speed Stationary Child

— Tesla AI (@Tesla_AI) November 24, 2024

Tesla has been previously greatly criticized for its ability to come to a safe stop for children playing on the road. Here, Tesla is demonstrating its capability of doing so - once again with highway speeds of 73mph. 

16. High-Speed Crossing Child

— Tesla AI (@Tesla_AI) November 24, 2024

And to really make the point - it can do it with a crossing child too. Tesla has made a strong commitment to safety for vulnerable road users, and this is a good way to show how it works.

That’s a lot of unique scenarios that Tesla tests against - and each and every build has to be vetted against this huge list of different safety tests in order to ensure that the build that ends up in customer hands is as safe as possible. With FSD v13 looking like it's coming soon, we’re excited to see where this takes Tesla next. 

With Musk announcing that FSD v13 is coming soon, it really is starting to feel like Unsupervised FSD and Robotaxi could be pushed out sometime next year.

Tesla's New Model Y to Receive Adaptive Headlight Support in U.S. Soon

@DriveGreen80167 on X

In the latest episode of Jay Leno’s Garage, Tesla’s VP of Vehicle Engineering, Lars Moravy, confirmed that the new Model Y will feature adaptive headlights.

As Moravy was talking about the updated headlights in the vehicle, which now sit a few inches lower than before, he stated that in a couple of months, Tesla will add adaptive headlights in the U.S.

While Tesla has already introduced adaptive headlights in Europe and the Indo-Pacific, the feature has yet to make its way to North America.

Originally delayed in the U.S. due to regulatory issues, manufacturers have been able to implement adaptive headlights since mid-2024. Meanwhile, competitors like Rivian and Mercedes-Benz have already rolled out their own full matrix headlight systems, matching what’s available in other regions.

Update: This article has been updated to clarify that adaptive headlights will indeed be launched in the U.S., shortly after the vehicle launching in March.

Adaptive Headlights

Back in October 2024, Lars confirmed that matrix headlight functionality was just around the corner for North America. However, as we enter 2025, it’s still unclear when Teslas with matrix headlights will receive the feature.

Currently, Tesla in North America supports adaptive high beams and automatic headlight adjustment for curves, but full matrix functionality has yet to be rolled out. Meanwhile, matrix headlights are already available in Europe, where they selectively dim individual beam pixels to reduce glare for oncoming traffic and adapt to curves in the road.

It was surprising that matrix functionality wasn’t included in the comprehensive 2024 Tesla Holiday Update. This feature would likely improve safety ratings, so we can only assume Tesla is diligently working to secure regulatory approval.

Adaptive Headlights on Other Models

Lars didn’t confirm whether the refreshed Model Y comes with the same headlights as the new Model 3 and the Cybertruck, instead simply calling them "matrix-style” headlights.

The headlights on the new Model Y appear very similar to those available in the 2024+ Model 3, possibly meaning these other models will also receive adaptive headlight capabilities in the next couple of months.

For vehicles with older-style matrix headlights, it’s unlikely that adaptive beams support will launch at the same time, but they will hopefully become available soon afterward.

You can check our guide here to see if your vehicle includes matrix headlights.

Tesla Starts Underwriting Its Own Insurance: Will They Insure Their Own Robotaxis?

Not a Tesla App

For the first time since launching Tesla Insurance in 2019, Tesla will begin underwriting its own policies, starting in California.

Tesla Insurance originally debuted in California and has since expanded to several U.S. states. Until now, policies were underwritten by State National, a subsidiary of the Markel Insurance Group. However, Tesla is now transitioning to fully in-house underwriting, beginning with its home state.

As part of this shift, California Tesla Insurance customers who receive an in-app offer to switch will be eligible for a one-time 3% discount on their next term’s premium—covered entirely by Tesla Insurance.

What is Underwriting

Underwriting is the process an insurance company uses to assess risk and determine whether to offer coverage, at what price, and under what terms.

Insurers evaluate factors such as driving history, credit score, age, vehicle type, and location. In Tesla’s case, vehicle driving data (not available in California) also plays a key role in risk assessment. These factors help classify drivers into risk categories, which influence their base premium.

From there, coverage limits, deductibles, and policy inclusions or exclusions can further adjust the final premium up or down.

Robotaxi and Other Benefits

At first glance, underwriting insurance might seem like a complex and costly process for Tesla. However, there are several compelling reasons why this move makes sense.

Insurance Income: Insurance is a highly profitable industry. Companies set rates based on risk, offering lower premiums to safer drivers and higher rates to riskier ones. This not only maximizes profitability but also incentivizes safer driving behavior, reducing overall claims.

Data Advantage: Tesla collects vast amounts of driving data through its Safety Score system. While California doesn’t allow Safety Score to impact premiums, Tesla can still use this data in the underwriting process to refine risk assessments and pricing for its vehicles.

Control Over Repair Costs: By underwriting its own policies, Tesla gains direct control over repairs and total loss decisions. This allows them to dictate when, where, and how repairs are done, optimizing costs for parts, labor, and service while ensuring vehicles are fixed according to Tesla’s standards.

FSD-Driven Discounts: Tesla has already begun offering insurance discounts for drivers using Full Self-Driving (FSD). By underwriting its own policies, Tesla could expand these incentives, potentially offering greater discounts to frequent FSD users in the future.

Preparing for Robotaxi: Perhaps the biggest long-term reason for this shift is the June launch of the Robotaxi fleet. How will Tesla insure these vehicles? The answer is simple—by underwriting its own policies and assuming liability.

Tesla’s decision to underwrite its own insurance isn’t just about cutting out middlemen—it’s a step toward lowering costs, increasing profitability, and preparing for the future of autonomous driving, a risk many insurance companies may be unwilling to make.

Further Expansion

This could be a strong sign that Tesla is preparing to expand its insurance offerings now that it has taken on the underwriting process itself. In July 2024, Tesla hired a former GEICO insurance executive to lead the expansion of Tesla Insurance and help reduce costs—a move that now appears to be paying off.

Rather than a traditional expansion, Tesla has instead made a bold move by bringing underwriting in-house, something few expected. However, it aligns with Tesla’s strategy of vertically integrating and controlling key aspects of its business, whether in manufacturing, software, or now, insurance.

If this pilot program proves successful, it could pave the way for Tesla Insurance to launch in more states—and potentially even other countries. With 2025 shaping up to be a pivotal year, we may see Tesla accelerate its insurance expansion sooner than expected.
