A Friday night cruise with Elon Musk has shown the world just how far Tesla’s Full Self-Driving has advanced and gave viewers a preview of real-world problems. To take a line from Rob Zombie, the latest iteration of FSD may be "More Human Than Human," which could be an issue.

"Nothing but net!" proclaimed Musk as he live-streamed to X.com, a video with more than 42 million views. The Tesla CEO referred to neural nets, the technology underpinning Version 12 of FSD. Tesla is removing 300,000-plus lines of code running the current FSD and is now relying on the car's neural networks to drive the car in V12.

Driving through Palo Alto, California, Musk, with Ashok Elluswamy, Tesla’s Director of Autopilot Software, sitting shotgun, picked random places for the Model S to drive to, and it did so smoothly and almost perfectly.

Technology Behind FSD

The test drive started with a construction zone, which was easily handled, but interestingly, at the end of the cones, the car wasn’t jerking over to find a lane immediately. Instead, like a confident human driver, it easily made its way to the lane with no oncoming traffic. We also watched as it effortlessly navigated speed bumps, roundabouts, pedestrians, bicyclists, and, of course - traffic.

For those who have had successful drives with FSD, you may be thinking, what's the big deal? Musk underscored that this version of FSD does not rely on hard-coded programming or a constant internet connection to function. All necessary inference occurs locally, a significant departure from previous versions.

“This is all nets, baby, nothing but net,” Musk exclaimed, emphasizing the vehicle’s dependency on machine learning rather than programmed instructions. The software operates at full frame rate, taking eight cameras at 36 frames per second to decide what to do. No line of code tells the car what to do at an intersection, on the highway or around other vehicles.

The software was impressive to watch, with its countless improvements over the current V11 version of FSD. Musk's vehicle kept a reasonable speed throughout the drive, even though Autopilot was set to a maximum speed of 85 mph.

When Musk reached his destination, the vehicle also automatically pulled over to the side of the road to park itself instead of just stopping in the middle of the road like it does today.

The Real-World, Real Person Challenge

Instead, Tesla has shown the car countless videos of real-world driving so that it will learn what to do in those situations. But that has caused a problem. As the car noticeably did not come to full stops, Musk explained the challenge posed by the fact that less than 0.5% of drivers come to a complete stop at stop signs.

This makes it incredibly difficult to program the vehicle with such sparse data on people obeying the law. This lack of data highlights Tesla's obstacles in training its AI systems to operate in real-world scenarios where human drivers frequently do not adhere to the rules.

Regulatory Hurdles

This appeared in a few other instances where the car behaved like a confident driver, not endangering anyone but technically breaking the rules of the road. FSD suddenly went from the nervous teenager learning to drive to a good driver. But we know how the NHTSA feels about Tesla not following the rules.

In February, the watchdog issued a recall stating that Tesla was acting too human — I mean not following the rules. It cited FSD Beta software:

  • Traveling or turning through certain intersections during a stale yellow traffic light;
  • The perceived duration of the vehicle’s static position at certain intersections with a stop sign, particularly when the intersection is clear of any other road users;
  • Adjusting vehicle speed while traveling through certain variable speed zones, based on detected speed limit signage and/or the vehicle’s speed offset setting that is adjusted by the driver.

Yes, I’m sure we all stop at every yellow light, come to a complete stop at every stop sign, and never go over the speed limit.

Kudos to Tesla and Musk for this real-world demonstration, and if there was any speculation that it was rigged, Musk did have to intervene at an advanced left-hand signal. This small glitch, Musk reassured, could be addressed with further training and data collection. There will be a lot of training announced Tesla’s commitment to invest $4 billion over the next two years in training computing, signaling the company's dedication to perfecting this groundbreaking technology.

Tesla Releases FSD V12.6.1 for Model 3 & Model Y

By Karan Singh

Last night, Tesla released software update 2024.45.25.15, which includes FSD V12.6.1. This update adds support for all HW3 vehicles, including the Model 3 and Model Y. We’re excited to see the continued support for HW3 owners. 

FSD V12.6.1

V12.6.1 is now going wide, according to Ashok Elluswamy, Tesla’s VP of AI. This update is going to the Model 3 and Model Y for the first time - as only the Model S and Model X were included in FSD V12.6. 

V12.6 is a big step forward for HW3 - it includes End-to-End on Highway, Improved City Streets Behavior, and Smoother and More Accurate Tracking - all contributing towards a better, smoother, and more comfortable build of FSD. You can read our comparison between FSD V12.6 and V13.2.2 here

In short, FSD V12.6 performs considerably closer to V13 than V12.5.4.2 - which is a massive improvement. It performs as well as the Cybertruck version of FSD V13, which is still missing a few features when compared to other HW4 vehicles, but it’s a great sign for HW3. A lot of the improvements can be pointed to in the improvements to lane selection and decision-making - the vehicle tends to hesitate far less on V12.6, meaning the ride is a lot smoother. Many early V12.6 testers mentioned that it felt more like V13-mini than anything else.

Legacy Model S & X

We haven’t seen this update hit any legacy Model S and Model X vehicles just yet. We’re not sure whether Ashok’s statement of “generally” applies here - but it should. If you do get the update, please let us know.

Legacy Model S and Model X vehicles are still on an older FSD build and potentially won’t see another FSD update for a little while longer. While they do have the same FSD hardware as other vehicles, there are enough hardware differences that require a build specifically for these vehicles.

Release Date

Update 2024.45.25.15

FSD Supervised 12.6.1 & 13.2.4
Installed on 0.4% of fleet
2 Installs today
Last updated: Jan 13, 7:30 am UTC

FSD V12.6.1 is going out now to the redesigned Model S and X with HW3 and all Model 3 and Model Y vehicles with HW3. The initial wave went out last night, and we expect to see more later today or tomorrow. If this release ends up going “wide,” we should see much larger waves go out next week.


Tesla Issues Physical & OTA Recall for Hardware 4 Computer

By Karan Singh

Tesla has issued a recall for some vehicles due to issues linked to a revision of the Hardware 4 (HW4) computer that was introduced this past November. This recall affects all vehicles with the revised hardware except for the Cybertruck, as it uses a slightly modified version of the HW4 system.

Many vehicle owners have reported a complete failure of their Autopilot computer, which not only leaves the vehicle without FSD and Autopilot but also disables many of the active safety features that make a Tesla what it is.

Let’s take a look at this recall - because the recall is partially physical and partially a software recall.

HW4 Failure

Tesla has identified the failure and flagged it to the U.S. NHTSA (but not Transport Canada or Euro NCAP at the time of publishing) as a recall.

Tesla mentions that the vehicle’s FSD computer circuit board may short circuit, resulting in the loss of the rearview camera image. The recall itself is focused on the rearview camera - as not having a functional rearview camera breaks a Federal Motor Vehicle Safety Standard. However, it does impact more than just the rearview camera.

As previously mentioned, users have experienced the full loss of Autopilot and FSD on these vehicles, as well as reduced traction control and removal of safety features such as automatic emergency braking, collision avoidance assist, and forward collision warnings. 

While the vehicle remains driveable, it is not necessarily a good idea to drive the vehicle with many of these features, especially with the reduced traction control noted by many people. We’ve already noted that while Tesla has been sending tow trucks to pick up some vehicles, it is also prompting owners to drive the vehicle to their service center in some cases.

Remedy

Unlike most of Tesla’s recalls, this one isn’t entirely an OTA recall, owing to the fact that people have already experienced circuit board shorts and are already waiting for replacements.

The software portion of the recall has already been mostly completed for any vehicles with Tesla software update 2024.45.25.3 or greater. However, a significant portion of the tracked fleet remains on update 2024.44.25.2 (approximately 20%), so we recommend updating your HW4 vehicle whenever you receive the notification.

On the hardware side, Tesla is immediately identifying and replacing hardware that has had circuit board failure. Tesla is also reaching out to customers who have expressed intermittent issues with Autopilot features, active safety features, or vehicle cameras that don't display correctly. If you have experienced any of these issues in a late 2024 vehicle, we recommend submitting a service ticket with Tesla to ensure that your vehicle isn’t affected by this recall.
