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.
