Tesla Update 2024.20 Lets Matrix Headlights Adapt to Curves, Adds Supercharger Leaderboards and More (2024)

Tesla has been on a roll with updates recently, and now update 2024.20 was released to employees over the weekend. This update builds on the many features in the Spring Update and adds a few big improvements.

Adaptive Headlights

New updates to Adaptive Headlights are arriving for European cars with matrix headlights. The new update allows the headlights to adapt to curves in the road ahead of you, enabling better illumination. Having the adaptive headlights work for curves is the second major update for matrix headlights. Update 2024.8 added adaptive high-beam support, letting your high beams stay on longer by turning off select LEDs in the headlights.

Update 2024.2 first brought adaptive high beams to the new Model 3, before it was later introduced to older vehicles with matrix headlights. At this time, it’s not clear whether the improvements to headlights around curves will be exclusive to matrix headlights or also support the new Model 3.

How to Tell If You Have Matrix Headlights

How do you know if you have matrix headlights on your Tesla? On the outer edge of the headlight, there will be a large, round projector dome, like in the image below. If there isn’t a dome, those are standard non-matrix headlights.
Another way to tell is to run a stock light show while facing a wall. If the Tesla logo, in letters, pops up, you have matrix headlights.

For now, North America still does not have adaptive headlight support, mostly due to legislative and testing issues in the United States. The US recently approved adaptive headlights, and a Tesla employee mentioned they’re working on it. Canada has legalized adaptive headlights since 2018, so we see this deployed in North America at some point in the future.

Supercharger Races on Beach Buggy Racing 2

Tesla is still improving its Arcade functionality, with the addition of local leaderboards at Superchargers in Beach Buggy Racing 2. It appears that each individual Supercharger site will have its own leaderboard, which drivers can compete on while their cars charge. Tesla says there will also be special races to compete in this Beach Buggy Racing 2 update.

Tesla owners can plug in and play with a controller, the touchscreen, or their vehicle’s steering wheel. Thanks to steer-by-wire on the Cybertruck, the actual wheels on the truck won’t move like they do on other Tesla models when playing the game.

We continue to hope that future refreshes to the S, 3, X, and Y will eventually receive steer-by-wire as well, as the feature has quite a few unique uses, whether driving or parked.

Autopilot Strikes and Suspension

An updated Autopilot Strike system, similar to the one that is on Tesla’s upcoming FSD V12.4 update, is on 2024.20 as well. At five strikes, users will be suspended from the use of Autopilot like before, but now Tesla will remove a strike for each 7-day period the driver goes without receiving a strike.

FSD 12.4 also improves vision-based monitoring and removes the steering wheel nag, but that’s not in this latest Tesla update, but will likely be added in the future.

Tesla tends to release new Autopilot features in their FSD updates before releasing them to the wider public for regular Autopilot use.

Hot Weather Improvements

The last set of user-end improvements coming in 2024.20 will be related to hot weather, the opposite of 2024.2.6’s cold weather update. This set of changes intends to improve AUTO mode HVAC performance in hot weather, helping to cool down the cabin faster, while also maintaining comfort at lower noise levels.

There have been several updates in the last six months to Tesla’s HVAC systems, all helping to deliver a quieter, more comfortable experience, with one of the last major ones introducing cool-down or warm-up periods before blowing air into the car cabin.

Chris Zeng, a Chinese Tesla content creator on X, recently posted an image with Tesla’s Spring Update – 2024.14, with the words “Employee FSD Beta Program: Registered.”

He also confirmed that although this text appears in the vehicle, there are no actual FSD features enabled yet.

FSD Beta Coming to China

Recently, Tesla began to offer Enhanced Autopilot subscriptions in China, and Chinese corporate giant Baidu announced that it will be providing enhanced 3D mapping for Tesla vehicles as well.

On a recent trip to China, Elon Musk spoke with Premier Li Qiang on the rollout of FSD to China. Later follow-ups said that “it may be possible [for FSD to arrive in China] very soon”.

FSD Shadow Mode

Tesla’s cars can operate FSD in Shadow Mode – which means that the vehicle is running FSD in the background without any real output except analytics. This is a common software practice that lets software engineers compare the process they’re testing against an existing known output and compare the results. In this case, Tesla compares what FSD would do to what the driver does, and any discrepancies are reported back to be analyzed.

With this information, we could guess that FSD has been operating in Shadow Mode in China for a while, and this new Employee FSD Beta Program will be the beginning of employee testing in China, providing even more data for the end-to-end process that is FSD V12.

FSD Beta, not Supervised FSD

Most interestingly, the photo refers to “FSD Beta” instead of “Supervised,” which Tesla started using with FSD 12.3.3 in March 2024. This could imply that FSD in China isn’t ready for a “Supervised” variant, and it’s considered to be in more of a testing stage.

In the photo, we can also see that it says “Wave 1,” which is what Tesla calls the group of employees who receive “pre-release” Tesla updates on their personal vehicles. Wave 1 serves as a final test for software before its released to the public. In most cases, the software is rolled out publicly within a couple of weeks, however, there have been times when bugs are found and Tesla releases revision before a public release.

Release Date

Prior to larger releases here in North America, we generally see Tesla ADAS (Advanced Driver Assistance Systems) testing and verification vehicles on the roads, which have not yet been spotted in China.

Whether these vehicles will be needed in China is up for debate, but once FSD features begin rolling out to employees, we should get a better idea of a public release in China.

Tesla’s latest set of updates has been fast-moving, with lots of bug fixes, and this fits with Musk’s philosophy of moving fast and breaking things. Some people are still on 2024.8.9, some are still on 2024.3.25, and some people are already on the 2024.14.8 Spring Update, and there’s also the brand-new 2024.20 update that just went out to employees for testing.

Let’s take a look at how Tesla’s software distribution system works, and why you are where you are.

Statistics

Before diving deep into how it all works, let’s get some statistics out of the way. We’ll be using the statistics we use here on the site, which are powered by TeslaFi.

As we can see, the tracked fleet is about 30% 2024.14 – the spring update; 2024.8 – Tesla’s previous major update, which contains FSD V11; and 2024.3 – the FSD V12.3 update. The remaining fleet on 2023.44 or other updates is fairly negligible, at around 10%.

So, about 65% of the tracked fleet has access to FSD V12, depending on their country of origin. The remaining 25% of the fleet only has access to FSD V11 if they’re in an eligible region.

FSD Update Track

When someone subscribes or purchases FSD in the U.S. or Canada, Tesla enables the FSD feature on that vehicle’s firmware, which currently could be either FSD v11 or FSD v12.

Once you’ve subscribed to FSD, you’re generally put on the ‘FSD Track,’ which means you’ll start receiving the latest FSD updates, like FSD v12.4. These updates are usually exclusive to FSD subscribers as they serve as a testing ground for the latest FSD revision. They’ve been update versions such as 2024.9.5, 2024.3.25, 2023.27.5 and so on. In the past year or so, they’ve all been odd week numbers, but that hasn’t always been the case.

However, the downside is that Tesla develops FSD at a different pace, and while you’re one of the earlier individuals to test out the latest FSD version, these updates are usually several major updates behind Tesla’s latest, meaning you don’t always have access to Tesla’s latest features. Currently, these are owners on update 2024.3.25 who are waiting on FSD v12.4, but still don’t have the Tesla features in update 2024.8 or 2024.14.

Vehicle Eligibility

Not all vehicles are eligible for all updates, and this is a twofold reason. First, if you’re on an update that is on a newer branch, say 2024.8.9, you cannot go down to 2024.3.5. The version number is broken down to year, week number and revision. So update 2024.8.9 is the 9th revision of the update that was created on the 8th week of 2024.

In general, Tesla does not roll back versions, so if someone is already on update 2024.14, then their vehicle wouldn’t be eligible for FSD 12.4, which is update 2024.9.5. This is mainly due to potential issues since Tesla doesn’t thoroughly test rolling back software.

Your vehicle will always be eligible for updates on a later branch, even if you won’t necessarily receive that update – like the many owners on update 2024.8 or 2024.3 who haven’t received update 2024.14 yet.

The second factor is hardware. Vehicles on older hardware variants, or vehicles that are considered to be legacy, are just not eligible for some updates. This is something that Tesla decides as newer hardware is needed for newer features and support for legacy hardware may not be included in all updates.

If you’ve subscribed to FSD and you’re on update 2024.8.9 and wondering why you’re not receiving update 2024.14, that’s why. Tesla wants your vehicle to be eligible for the next FSD v12.4 update, which will be update 2024.9.5.

Vehicle Variants

Sometimes, updates are not sent out widely for the simple reason of hardware variants. Tesla’s fleet has become widely fractured over the years, with many different variants of vehicles on the road today. Some 2022 Model Y’s may have Matrix headlights, while some may not, and some may have USS, while others don’t. Most have HW3, but a few have HW4!

That’s 6 possible branching variants in one year – a total of 24 possible variants for just the 2022 Model Y, not including the Performance, Long-Range, Rear-Wheel Drive, 4680-cell Rear-Wheel Drive, and the odd 2022 Standard-Range Dual-Motor variants that are also all different! If you did the math, there are 362 thousand possible variants, but not likely more than ~40 or so actual builds that Tesla differentiates between for software for all vehicles.

Of course, Tesla has managed to pare down these variants through the 2023 and 2024 model years, with greatly simplified production chains, with the removal of USS in favor of Tesla Vision, the full move to Hardware 4 across all factories, and Matrix headlights becoming standard globally. But all those existing vehicles are not legacy, and still need updates.

That means a complex and well-thought-out update process has to be built in order to deploy a functional update to all these vehicle variants.

Bug Fixing

Besides the complexity of vehicle variants, Tesla also has to catch and fix bugs. No matter how good one is at software development, sometimes bugs just escape into the wild. And fixing those bugs is essential since they could leave a vehicle undriveable. Although a major issue is rare, Tesla has had some issues in the past, such as Automatic Emergency Braking being disabled due to a software issue. This is why Tesla rolls out updates gradually.

We’ve seen this play out with update 2024.14, which has received numerous bug-fix releases. Tesla will release an update to a set of cars, discover an issue, and stop the rollout. A few days later, another update is out with additional fixes, and so on.

Conclusion

So, if you’re stuck on update 2024.8.9 or 2024.3.25, and are wondering when you’ll get FSD V12 or the Spring Update, you’ll have to hang on – the author is also on 2024.8.9 with V11!

Elon Musk mentioned on X that FSD V12.4 should be the update the reduces FSD branching and will bring everyone to FSD V12 in general. 2024.9.5 is the FSD V12.4 update, and it looks like vehicles that are below that branch number should be collectively receiving the reduced-nag V12.4 update.

When we finally receive FSD V12.4, we’ll likely need to hang on for a little longer until FSD V12.4.1 or FSD V12.5 rolls along to have the Spring Update.
