In a recent interaction on X, Elon Musk confirmed that the long-standing steering wheel nag, designed to ensure driver attentiveness, would be removed in FSD v12.4.

Musk initially replied to a user on X claiming that FSD v12.4 would fix the steering wheel nag. However, it wasn't clear what Musk meant by fixed until user, Farzad, created another post stating that Musk insinuated that the nag would be removed in FSD v12.4, to which Musk replied with “Yes.”

Tesla's removal of the steering wheel nag isn't surprising, as Tesla's camera-based driver monitoring system in the vehicle can in theory do a much better job monitoring the driver's attentiveness. So before NHTSA has a heart attack with Musk's comment, it's important to understand that Tesla is likely improving cabin camera monitoring in this same update to the point that the steering wheel nag becomes redundant.

How Tesla Uses the Cabin Camera

Tesla uses the cabin camera to detect whether a driver is paying attention to the road by detecting whether their eyes are open, which way their head is facing, and even whether the driver is using their phone.

Thanks to Tesla hacker Greentheonly, we know Tesla uses the vehicle’s interior camera output and AI to determine the likelihood of each scenario they're looking for. For example, Tesla runs neural networks that look at the video feed of the cabin camera and determine whether the driver is looking up at the road, looking off to the side, or looking down.

This Won't be the End of the Steering Wheel Nag

While Musk's statement implies the removal of the steering wheel nag, Tesla will probably retain it as a fallback measure, at least in early iterations of the suspected improved camera-based monitoring system.

The steering wheel nag may still be used when the cabin camera can't confidently determine whether the driver is paying attention. This could be caused by sunglasses, hats, glare, or even driving at night. Newer Teslas include interior infrared lights that help the camera see in the dark, although not all Teslas on the road include infrared lights.

Will It Also Remove It For Basic Autopilot?

While Musk says Tesla will remove the steering wheel nag in FSD v12.4, the need to detect driver attentiveness isn’t unique to FSD. Tesla detects for driver attentiveness in all their Autopilot packages, including Basic Autopilot, Enhanced Autopilot, and FSD. It’s not clear whether Tesla plans to only remove the nag in FSD, but it looks like Tesla will at least start there and the feature will likely work its way down to Enhance Autopilot and Basic Autopilot as well.

Vehicles Supported

The only Teslas expected to take advantage of the “nag-less” improvements in FSD v12.4 are those with cabin cameras, which include the Model 3, Model Y, Cybertruck, and the redesigned Model S and Model X. However, the newest vehicles with infrared lights near the cabin camera will likely benefit the most.

FSD v12.4 Release Date and Features

Elon Musk indicated that FSD v12.4 could start rolling out as early as next week. Musk doesn't usually reveal what's in each FSD update, but he did talk about what we should expect in FSD v12.4, disclosing that the update will largely focus on refining passenger comfort by addressing concerns such as abrupt acceleration and braking.

Musk went on to tease some of the improvements to expect in subsequent versions like v12.5 and v12.6, but the primary focus of v12.4 seems to be delivering a smoother and better driving experience.

Tesla Vehicles Spotted With LiDAR: What Do They Use It For?

Tesla recently hit the news for purchasing approximately $2M in LiDAR sensors from Luminar, one of Tesla’s long-term suppliers. You’ve probably seen photos of Tesla’s Semi and various Tesla models, including the Model 3 and Model Y sporting LIDAR equipment on the roof. These cars drive around with manufacturer plates scanning streets and highways.

However, many people confuse Tesla’s purpose in purchasing LiDAR equipment with using it for FSD versus testing. So, let’s look at what LiDAR is, and why Tesla uses it on its Fleet Validation Vehicles.

What is LiDAR?

LiDAR stands for Light Detecting and Ranging – essentially using lasers to measure distances. A laser pulse is sent out, and the time it takes to return is measured – providing extremely accurate distance measurements.

Some companies working on self-driving vehicles, including Waymo and BYD, use LiDAR as part of their self-driving suites, but Tesla is one of the few stand-outs that does not. Even Rimac’s “Verne” Robotaxi – which uses self-driving technology from Mobileye, also uses LiDAR.

While LiDAR can produce extremely accurate and high-quality 3D environments, it comes with its downsides as well. Not only is LiDAR costly and requires large gear strapped to a vehicle, but it also can not be used in bad weather and can have interference issues if there are other strong light sources present.

Why Does Tesla Use LiDAR?

At Autonomy Day in 2019, Elon Musk mentioned that LiDAR isn’t the solution for self-driving cars – it's just a crutch. Thus, Tesla hasn’t used LiDAR for any production self-driving software.

Instead, Tesla uses it exactly how it's described – they use it to gather ground-truth data. This data is then used to feed Tesla’s Full Self Driving system – which helps validate its vision-only system's accuracy. LiDAR provides very accurate measurements to help ensure that FSD’s perception of space is accurate – and is only used by Tesla to ensure that its AI technology which is the brains of FSD is capable of accurately interpreting depth from just visual data.

Tesla’s vision-only system has been seen to be extremely accurate, with Vision-only Autopark being able to park in even narrower and tighter spaces faster than the previous version that relied on ultrasonic sensors.

We’ll likely continue to see Tesla purchase LiDAR systems, as well as use them for validation well into the future.

Tesla's Upcoming Robotaxi Event in August Delayed, According to Bloomberg

In a report from Bloomberg, it is claimed that Tesla will be delaying its much-anticipated 8/8 Robotaxi event by two months to October 2024.

While sources other than Bloomberg haven't confirmed this report, Bloomberg has a positive track record of reporting on financial decisions. We’ll be sure to update the article if there is confirmation on X from Elon Musk or another Tesla senior official.

Tesla’s stock has dropped nearly 8.5% over the day, ending back-to-back gains over the last two weeks. It closed yesterday at $ 241 after hitting a peak of $270 earlier in the day before the news broke.

Why the Delay?

The delay – of approximately two months – has been communicated internally, but not publicly announced just yet. Bloomberg goes on to mention that the design team was told to rework certain elements of the Cybercab, necessitating the delay.

If Bloomberg’s report is correct, it sounds like Tesla’s unveil event will be largely focused on showing off the vehicle, instead of demoing how it will work. Of course, it could still be both, but given past events, Tesla has always shown off the vehicle years before it hits production.

Rimac recently showed off their version of robotaxi vehicle named Verne, and surprisingly, it could almost pass for Tesla’s own robotaxi. A lot of design cues in Rimac’s version are elements we have already seen or expect to see in Tesla’s autonomous taxi.

A recent Tesla patent revealed that Tesla is incorporating a sanitation system into their robotaxi that will be responsible for analyzing and cleaning the vehicle’s interior, although the delay itself is likely tied more to a physical feature rather than software.

Another element we know almost nothing about is how Tesla plans to charge these robotic taxis. Will they rely on the existing charge port and adapt a solution like the robotic charging arm (video below) we saw almost eight years ago, or will wireless charging or a dock finally become realized?

While the delay for Tesla’s event appears to be related to the vehicle’s design itself and not further development of FSD, Tesla is wasting no time in getting FSD working for the upcoming vehicle. Model 3 vehicles have already been spotted with camera locations that resemble a robotaxi.

Is the Delay Accurate?

We expect that this delay might actually be true – Elon Musk usually takes to X within hours of such news breaking if it's false to refute it and hasn’t done so yet.

Tesla has delayed several of their events in the past, and a delay of a couple of months seems plausible. We should hear from Musk himself soon on whether this report is accurate.
