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

— Tesla AI (@Tesla_AI) November 24, 2024

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)

— Tesla AI (@Tesla_AI) November 24, 2024

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)

12. U-Turn Cut-In (Occluded) pic.twitter.com/gp7H720mJd

— 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 Updates Santa Mode & Rainbow Road to Use Ambient Lighting and Updates SteamOS [VIDEO]

Flo / Roberto Bonato

While Tesla’s 2024 Holiday Update brought many new features, including Apple Watch Support, Cross Traffic Alerts, Weather Overlays, Search Along Route, and others, there are also several smaller items in this update that didn’t get much attention.

Ambient Lighting Now Affects Rainbow Road & Santa Mode

The 2024+ Model 3 and Cybertruck both come equipped with ambient lighting, and Tesla is now taking advantage of this custom lighting feature by incorporating it into several easter eggs.

Rainbow Road: If you head over to Apps > ToyBox > Rainbow Road, you’ll find a new option available that allows the ambient lighting in the vehicle to also change shades while Rainbow Road is active. The Rainbow Road easter egg is a tribute to the iconic course course in Nintendo’s Mario Kart.

Check out the feature in action below:

🇮🇹 Con l’aggiornamento di Natale, quando attiviamo la pista arcobaleno, anche i LED interni diventeranno arcobaleno. Questa è una novità non documentata, scovata da un utente di TESLERS (chiaramente riguarda le Model 3 Highland)

🇺🇸 UNDOCUMENTED CHANGE: With the Holiday update,… pic.twitter.com/xyocOIrWfX

— 𝗧𝗘𝗦𝗟𝗘𝗥𝗦 (@TeslersOfficial) December 8, 2024

Santa Mode: Just in time for Christmas, Tesla has improved Santa Mode by cycling the ambient lighting between Christmas colors. Similar to Rainbow Road, the use of ambient lighting for the easter egg is optional and can be enabled under Apps > ToyBox > Santa Mode.

When using Santa Mode with ambient lighting turned on, the lights will cycle just between Christmas colors, red, green and white, instead of the full rainbow. There’s a video of the feature below:

Yup and in Santa Mode it cycles between red white and green pic.twitter.com/HVQUlfUyze

SteamOS (Beta) Update

The Model S and Model X vehicles that support Steam gaming are receiving a Steam app update in the holiday update as well. This update could end up being very interesting, but for now Tesla says that the SteamOS, which also runs on Valve’s Steam Deck has been updated to version 3.6.

Valve outlines a wide range of fixes and improvements in their release notes for version 3.6, but Tesla simply states that the OS update includes performance enhancements and improved game compatibility.

The SteamOS hasn’t been updated on the Model S and X for quite a while, so we believe there may be more to this besides performance improvements and fixes. We’ll be looking to share some insights into this in the near future.

So, there you have it—three new features in the Holiday update that have mostly gone under the radar. While they may not apply to everyone, there are plenty of other cool features in the Holiday Update, like the arrival of Dynamic Road Closure Routing and Nearby Parking, that are coming to every vehicle, so go check out the full release notes.

New Report Offers Specs & Price for Tesla's Upcoming Next-Gen Model

A concept of Tesla's 'Model Q'

@DominicBRNKMN on X

At the 2023 Q3 Earnings Call, Tesla provided an update on its next-generation model, what many are referring to as the “Model 2” or “Model Q.” Although the actual model name is yet to be determined, it is known internally as Redwood.

During the 2024 Shareholder Meeting, Musk again mentioned the upcoming model, saying that Tesla is working on new products, including a more affordable vehicle and a larger SUV.

While we know the next-gen vehicle is aimed at the $25k to $30k USD market, we now have some new information thanks to a new report out of China.

Launch & Price

According to the Chinese outlet CNMO Technology News (Sina Finance), Travis Axelrod, Tesla’s Head of Investor Relations, announced plans to launch a new model. Axelrod shared this update while addressing senior corporate investors at an investor conference hosted by Deutsche Bank on December 5, 2024.

The goal of Project Redwood, internally dubbed “Model Q” by Deutsche Bank, is to achieve a post-subsidy price of under $30,000 USD. With the Federal EV Rebate potentially expiring next year, this suggests that the Model Q’s starting price will be around $30,000 USD. For comparison, the Model 3 currently starts at $42,490 in the U.S.

We previously reported that Tesla has already been speaking to suppliers and is looking to begin volume production of the vehicle sometime around June 2025. Of course, prototyping is still necessary, but we haven’t seen any signs of Tesla testing a new vehicle since spotting the Cybercab on the streets ahead of We, Robot.

Specs

The Model Q will supposedly be about 15% smaller and 30% lighter than the Model 3, with an approximate length of 3,988mm, or 157 inches. For scale, the Mini is 157 inches, while the Model 3 is 185 inches, so it’s fairly compact.

The battery will also be smaller to match the vehicle’s smaller size as Tesla tries to reduce the vehicle’s price while maintaining a similar range as its other vehicles. Tesla is expected to offer two models—a single-motor RWD model and a Long-Range Dual-Motor AWD variant.

There’s no news yet on the price of the AWD version, but we expect it to be about $5,000 more expensive than the RWD variant.

Once the vehicle ramps up in production, Tesla intends to produce about 10,000 of these per week globally or about 500,000 per year. As Tesla mentioned during one of their previous earnings calls, this next-gen vehicle will be built using Tesla’s current assembly lines with minimal changes. This should allow for a smoother and more predictable production ramp. While Tesla still plans to use its new unboxed assembly process, it’s now saving it for the robotaxi.

Project Juniper

One of the items that came up during the investor conference was Tesla’s Project Juniper—the Model Y refresh. Juniper has already had a few leaks, including some images and information that mention a return to the 7-seat, 3-row format—at least in China. 

We’re expecting Juniper to launch early next year, as production has supposedly already begun at Giga Shanghai, at least on a limited prototyping basis. If the rollout matches the Model 3 Highland refresh, we’ll see Juniper arrive in China first and then make its way to North America and Europe by the end of 2025. The performance variants should launch in early 2026, after the standard models.

If you’re excited about Juniper, so are we! Check out our wishlist of features for Tesla’s Model Y refresh, and see everything we know so far.
