Tesla has just released software update 2024.32.30 to its early access customers this morning, with quite a few changes. What’s most exciting is that there isn’t a “Coming Soon” section in there, as this update includes all of those features.
This may mean that FSD v12.5.6 may be the big update that concludes FSD V12, as FSD V13 is already on the Tesla FSD Roadmap for October. But before we look too far forward, let’s take a look at what the early access folks received this morning.
Of course, this build includes Vision-Based Attention Monitoring, including sunglasses support, and end-to-end highway monitoring. It also includes " earlier and more natural lane change decisions,” “Updated Driver Profiles,” and “Auto Set Speed has been updated to Max Speed.”
Earlier and More Natural Lane Change Decisions
Since its inception, Tesla’s FSD has struggled to make natural lane change decisions, especially in advance of a coming turn or exit. Tesla has been working on improving when and how it makes these decisions, and this update should be the big one.
Early access testers have already mentioned that FSD V12.5.6 appears to make decisions a lot sooner than before, which is definitely a good thing. Previously, FSD would make decisions to get from the right lane into the left turning lane in under a few hundred yards (or meters) from the actual place you’re turning. This update should make everything much, much smoother.
Updated Driver Profiles
Tesla has replaced the three older FSD Modes with updated Driver Profiles instead (not to be mixed up with a Driver Profile that saves user preferences). Chill makes a come back here, but Average has been replaced with Standard, and Assertive has been replaced with Hurry. Hurry mode was previously announced by Elon in a post on X, and it has finally shown up a few short months later.
Tesla is a lot more clear on what each of these modes means, and how it’ll change the way FSD drives.
Chill
Chill says that it will drive in slower lanes with minimal lane changes. This one is going to be especially important because it seems like the minimal lane changes button is gone too. So if you want minimal lane changes for your drive – you’ll be on the Chill profile.
We expect Chill to stick to the right lane whenever possible – as that’s the “slow” lane in North America – and that should carry over to both the highway, as well as multi-lane roadways.
Standard
Standard is the new Average – it offers to drive at normal speed, adjusting with traffic. We’re not sure exactly what that means just yet, especially since Autospeed is gone (more on that below!), but it will likely work within the Max Speed to dynamically adjust based on how fast traffic around you is traveling.
If anything, Standard will be slightly more assertive and faster than Chill, but likely won’t be looking to park itself in the right lane or left lane – rather picking the more neutral center lane, especially on the highway.
Hurry
Hurry is the new mode, replacing Assertive. Hurry says that it will drive faster, with more frequent lane changes. It seems the intention of the Hurry Profile will be to get you to your destination just that much quicker.
Hurry will be fairly aggressive with its lane changes and its ability to drive faster. This means it will likely be looking for and taking opportunities to get ahead or through the flow of traffic where available. On the highway, this profile will likely bring you to the left lane, where you’ll be keeping up or passing traffic.
The Hurry Profile, in particular, will also be displayed when it’s in use, right next to the green attention-monitoring dot. It seems Standard and Chill currently do not display up there.

Auto Set Speed Has Been Replaced
On FSD V12.5.6, Autospeed is gone. It has been replaced with an updated version of its predecessor – Max Speed Offset. You can now set a Max Speed Offset for all FSD profiles, including negative offsets, to drive below the speed limit.
The maximum offset available right now is 40% - so if the limit is 50mph, your FSD speed limit will be 70mph. The minimum offset is also -40% - so at 50 mph, that’s 30mph.
This is definitely a new approach, as Tesla was previously working on letting its neural nets dynamically adjust the speed based on road and weather conditions, traffic around you, and road types (country vs low-density urban vs high-density urban).
We think Max Speed Offset will work very similar to Auto Set Speed, but with a clearer indication of the vehicle’s max speed. Previously on Auto, it wasn’t clear how fast the vehicle could go, just that the car was trying to determine the correct speed for the situation. Max Speed Offset is still expected to slow down for varying traffic and weather conditions.
Just like before, quick controls are available on the right scroll wheel.

When’s It Coming?
Okay, the big question everyone is waiting for. It's just hit early access testers on Model Y and Model 3 vehicles—with HW4. Assuming the build tests well, the earliest it will see customers will be sometime next week, likely with HW4 3/Y and Cybertrucks first, then the S/X, and then Hardware 3 in the coming weeks. However, this is just a guess based on previous releases. We hope HW3 vehicles get included much sooner.
The Super Manifold is Tesla’s solution to reducing the complexity of a heat pump system for an EV. Tesla showed off its engineering chops back with the original Model Y in 2019, where it introduced a new 8-way valve (the Octovalve) and a new heat pump alongside the uniquely designed Super Manifold to improve efficiency.
Now, Tesla is launching an improved version with the refreshed Model Y - the Super Manifold V2. We got to hear about it thanks to Sandy Munro’s interview with Tesla’s Lars Moravy (Vice President of Vehicle Engineering) and Franz Von Holzhausen (Chief of Vehicle Design). You can watch the video further below.
What Is The Super Manifold?
The Super Manifold (get it, Superman?), is an all-in-one package that brings in all the components of a heat pump system into one component. The Super Manifold packs all the refrigerant and coolant components around a 2-layer PCB (printed circuit board).
This Super Manifold would normally have 15 or 20 separate components, but Tesla managed to integrate them all into one nice package. That presented Tesla with a new challenge: how to integrate a heat pump—capable of both heating and cooling—into a single, efficient platform?
Several years ago, Tesla designed the Octovalve. It combines inlets and outlets and can variably change between heating or cooling on the fly - without needing to be plumbed in different directions. This is especially important for EVs, which may need to heat the battery with the waste heat generated from the motors or the heat pump while also cooling the cabin - or vice versa.
Original Super Manifold V1.1
Tesla launched the Super Manifold V1.1 back in 2022, and it provided some minor improvements to the waste heat processing of the heat exchange system. It also tightened up the Octovalve, preventing the leakage of oils into the HVAC loop that could cause it to freeze at extremely low temperatures.
Tesla has been using the V1.1 for several years now, and it has really solved the vast majority of issues with the heat pump system that many older Model Ys experienced.
Super Manifold V2 Coming Soon
Now, Tesla is introducing the Super Manifold V2 in the new Model Y. It will improve the overall cooling capacity provided by the original Super Manifold, but unfortunately, not every single new Model Y will come with it equipped. Tesla will be introducing it slowly across the lineup and at different rates at different factories, depending on part availability.
Eventually, the Super Manifold V2 will also make its way to other vehicles, potentially including the upcoming refresh for the Model S and Model X, but initially, it’ll be exclusive to the new Model Y. Tesla expects to have the new manifold in every new Model Y later this year.
If you’re interested in checking out the whole video, we’ve got it for you below.
Mark Rober, of glitter bomb package fame, recently released a video titled Can You Fool A Self-Driving Car? (posted below). Of course, the vehicle featured in the video was none other than a Tesla - but there’s a lot wrong with this video that we’d like to discuss.
We did some digging and let the last couple of days play out before making our case. Mark Rober’s Wile E. Coyote video is fatally flawed.
The Premise
Mark Rober wanted to prove whether or not it was possible to fool a self-driving vehicle, using various test scenarios. These included a wall painted to look like a road, low-lying fog, mannequins, hurricane-force rain, and bright beams.
All of these individual “tests” had their own issues - not least because Mark didn’t adhere to any sort of testing methodology, but because he was looking for a result - and edited his tests until he was sure of it.
Interestingly, many folks on X were quick to spot that Mark had been previously sponsored by Google to use a Pixel phone - but was using an iPhone to record within the vehicle - which he had edited to look like a Pixel phone for some reason. This, alongside other poor edits and cuts, led many, including us, to believe that Mark’s testing was edited and flawed.
Flaw 1: Autopilot, Not FSD
Let’s take a look at the first flaw. Mark tested Autopilot - not FSD. Autopilot is a driving aid for lane centering and speed control - and is not the least bit autonomous. It cannot take evasive maneuvers outside the lane it is in, but it can use the full stable of Tesla’s extensive features, including Automatic Emergency Braking, Forward Collision Warnings, Blind Spot Collision Warnings, and Lane Departure Avoidance.
On the other hand, FSD is allowed and capable of departing the lane to avoid a collision. That means that even if Autopilot tried to stop and was unable to, it would still impact whatever obstacle was in front of it - unlike FSD.
As we continue with the FSD argument - remember that Autopilot is running on a 5-year-old software stack that hasn’t seen updates. Sadly, this is the reality of Tesla not updating the Autopilot stack for quite some time. It seems likely that they’ll eventually bring a trimmed-down version of FSD to replace Autopilot, but that hasn’t happened yet.
Mark later admitted that he used Autopilot rather than FSD because “You cannot engage FSD without putting in a destination,” which is also incorrect. It is possible to engage FSD without a destination, but FSD chooses its own route. Where it goes isn’t within your control until you select a destination, but it tends to navigate through roads in a generally forward direction.
The whole situation, from not having FSD on the vehicle to not knowing you can activate FSD without a destination, suggests Mark is rather unfamiliar with FSD and likely has limited exposure to the feature.
Let’s keep in mind that FSD costs $99 for a single month, so there’s no excuse for him not using it in this video.
Flaw 2: Cancelling AP and Pushing Pedals
Many people on X also followed up with reports that Mark was pushing the pedals or pulling on the steering wheel. When you tap on the brake pedal or pull or jerk the steering wheel too much, Autopilot will disengage. For some reason, during each of his “tests,” Mark closely held the steering wheel of the vehicle.
This comes off as rather odd - at the extremely short distances he was enabling AP at, there wouldn’t be enough time for a wheel nag or takeover warning required. In addition, we can visibly see him pulling the steering wheel before “impact” in multiple tests.
Over on X, techAU breaks it down excellently on a per-test basis. Mark did not engage AP in several tests, and he potentially used the accelerator pedal during the first test - which means that Automatic Emergency Braking is overridden. In another test, Mark admitted to using the pedals.
Flaw 3: Luminar Sponsored
This video was potentially sponsored by a LiDAR manufacturer - Luminar. Although Mark says that this isn’t the case. Interestingly, Luminar makes LiDAR rigs for Tesla - who uses them to test ground truth accuracy for FSD. Just as interesting, Luminar’s Earnings Call was also coming up at the time of the video’s posting.
Luminar had linked the video at the top of their homepage but has since taken it down. While Mark did not admit to being sponsored by Luminar, there appear to be more distinct conflicts of interest, as Mark’s charity foundation has received donations from Luminar’s CEO.
Given the positivity of the results for Luminar, it seems that the video had been well-designed and well-timed to take advantage of the current wave of negativity against Tesla, while also driving up Luminar’s stock.
Flaw 4: Vision-based Depth Estimation
The next flaw to address is the fact that humans and machines can judge depth using vision. On X, user Abdou ran the “invisible wall” through a monocular depth estimation model (DepthAnythingV2) - one that uses a single image with a single angle. This fairly simplified model can estimate the distance and depth of items inside an image - and it was able to differentiate the fake wall from its surroundings easily.
Tesla’s FSD uses a far more advanced multi-angle, multi-image tool that stitches together and creates a 3D model of the environment around it and then analyzes the result for decision-making and prediction. Tesla’s more refined and complex model would be far more able to easily detect such an obstacle - and these innovations are far more recent than the 5-year-old Autopilot stack.
While detecting distances is more difficult in a single image, once you have multiple images, such as in a video feed, you can more easily decipher between objects and determine distances by tracking the size of each pixel as the object approaches. Essentially, if all pixels are growing at a constant rate, then that means it’s a flat object — like a wall.
Case in Point: Chinese FSD Testers
To make the case stronger - some Chinese FSD testers took to the streets and put up a semi-transparent sheet - which the vehicle refused to drive through or drive near. It would immediately attempt to maneuver away each time the test was engaged - and refused to advance with a pedestrian standing in the road.
Would FSD hit a transparent film wall? This test showed it just avoids it.
Thanks to Douyin and Aaron Li for putting this together, as it makes an excellent basic example of how FSD would handle such a situation in real life.
Flaw 5: The Follow-Up Video and Interview
Following the community backlash, Mark released a video on X, hoping to resolve the community’s concerns. However, this also backfired. It turned out Mark’s second video was of an entirely different take than the one in the original video - this was at a different speed, angle, and time of initiation.
Mark then followed up with an interview with Philip DeFranco (below), where he said that there were multiple takes and that he used Autopilot because he didn’t know that FSD could be engaged without a destination. He also answered here that Luminar supposedly did not pay him for the video - even with their big showing as the “leader in LiDAR technology” throughout the video.
Putting It All Together
Overall, Mark’s video was rather duplicitous - he recorded multiple takes to get what he needed, prevented Tesla’s software from functioning properly by intervening, and used an outdated feature set that isn’t FSD - like his video is titled.
Upcoming Videos
Several other video creators are already working to replicate what Mark “tried” to test in this video.
To get a complete picture, we need to see unedited takes, even if they’re included at the end of the video. The full vehicle specifications should also be disclosed. Additionally, the test should be conducted using Tesla’s latest hardware and software—specifically, an HW4 vehicle running FSD v13.2.8.
In Mark’s video, Autopilot was engaged just seconds before impact. However, for a proper evaluation, FSD should be activated much earlier, allowing it time to react and, if capable, stop before hitting the wall.
A wave of new videos is likely on the way—stay tuned, and we’ll be sure to cover the best ones.
