After a month-long delay, Tesla sent FSD v12.4.2 to employees yesterday with update 2024.15.10. After just a few hours of the update going out to employees, Tesla started sending it to OG testers as well, who were already on FSD v12.4.1.
Issues Behind Delay
On X, Elon Musk broke down some of the details behind the delays. He mentioned that part of the issues behind the V12.4.2 delays were based on training. Tesla was seeing fewer interventions with FSD v12.4, but the release suffered from driving smoothness, which ironically was supposed to be one of the key features of this release.
Musk explained that part of the issue was due to too much focus on interventions, and not enough on normal driving. He compared it to training a doctor on emergency room patients, versus training on regular preventative care.
Vision-Based Attention Monitoring Changes
With FSD update 12.4.2, Tesla changed some of the language used for its Vision-Based Attention Monitoring in the release notes. Here’s a breakdown of some of the key points in the language. The changes to the release notes are below. Phrases or words that were removed are crossed out, while those added are in bold.
“When Full Self-Driving (Supervised) is enabled, the driver monitoring system now primarily relies on the cabin camera to determine driver attentiveness. This enhancement is available on vehicles equipped with a cabin camera and only when the cabin camera has clear and continuous visibility of the driver's eyes Cabin camera must have clear visibility (e.g., the camera is not occluded, eyes, arms are visible, there is sufficient cabin illumination, and the driver is looking forward at the road ahead and not wearing sunglasses, a hat with a low brimwithout sunglasses, or other objects covering thetheir eyes). Outside of theseIn other circumstances, the driver monitoring system will continue toprimarily rely on a combination of torque-based (steering wheel) and vision-based monitoring to detect driver attentiveness. When the cabin camera is actively monitoring driver attentiveness, a green dot appears next to the steering wheel icon on the touchscreen.
If the cabin camera detects inattentiveness the driver to be inattentive, a warning will appear. The warning can be dismissed by the driver immediately reverting their attention back to the road ahead. Warnings will escalate depending on the nature and frequency of detected inattentiveness, with continuous inattention leading to a Strikeout.
Cabin camera images do not leave the vehicle itself, which means the system cannot save or transmit information unless you enable data sharing.”
Arms Need to be Visible and Other Changes
There are various interesting changes here. While some of the changes are just improved wording to make the feature clearer, there are others that are worth highlighting which could point at changes to Tesla’s vision-based monitoring.
The first is the addition of “arms are visible.” Apparently, Tesla now wants to be able to see your arms to better detect attentiveness. Tesla may want to see that your arms are on the steering wheel, or they maybe they want to make sure your arms are moving so that someone isn’t able to post a static photo in front of the cabin camera to circumvent the attention monitoring. The reason isn’t clear, but looks like having your arms visible is now a requirement.
There are other small changes like the removal of a “hat with a low brim,” which was replaced by more generic wording that says the driver’s eyes must be visible.
However, near the end, Tesla removed the portion that said the driver monitoring system will rely on a combination of torque-based (steering wheel) and vision-based monitoring. This was changed to simply say that Tesla will rely primarily on torque-based (steering wheel) monitoring when vision-based monitoring is unavailable. It’s not clear whether this is just semantics and the wording now better describes how the vision-monitoring feature works, or if Tesla made changes so that the vehicle is simply either doing vision monitoring or steering wheel torque detection, and it doesn’t try to combine the two sources to detect whether the driver is paying attention.
Even more interestingly, the last line that says “cabin camera images do not leave the vehicle itself, which means the system cannot save or transmit information unless you enable data sharing,” has been removed. This could point to Tesla saving images of the cabin camera to improve its AI training model.
Either way, we’re glad to finally see FSD v12.4.2 going out to employees and early-access owners. The release is expected to have far fewer interventions and improve vehicle smoothness during braking and acceleration. If there are no major issues found, this update could go wide to all customers with FSD and on update 2024.14 or lower in the coming weeks.

Back in 2023, Tesla put together a rather unique Supercharger site idea - one with a CyberCanopy. This canopy is intended to provide solar power for Supercharging, helping to reduce the impact on the local grid while also providing a futuristic and Cybertruck-themed location that would set it apart.
Unfortunately, the plans never moved beyond the filing stage. Instead, Tesla opened a standard-looking Supercharger at the same Canton, Massachusetts location. However, the site is still well-situated just off the highway and benefits from natural tree cover in the parking area.
However, Tesla is at it again with a concept for another CyberCanopy with RGB lighting. Thanks to MarkoRP for spotting this. No April Fool’s this time.
We want to build a few Superchargers cool enough to be worthy of the trip itself. - Max de Zegher
CyberCanopy 2
This second Supercharger with CyberCanopy is set for Roswell, New Mexico, at the Whataburger in town. Featuring just eight stalls, this will be one of Tesla’s smaller Supercharger sites, but for what it lacks in size, it makes up for it in uniqueness. The charging stalls are covered from the rain by a futuristic, Cybertruck-themed canopy, which will have solar panels installed on the top of it.
According to the plans, the CyberCanopy boasts 20.88kW of solar panels on its roof, providing shelter from the elements while also providing some power back to the grid.
RGB Lighting
At nighttime, the Supercharger will make a big statement. Tesla intends to light the long edges of the canopy, which will not only look amazing, but it’ll actually make finding the Supercharger easier in a large parking lot.
The lighting coming off the edge of the canopy reminds us a lot of the lightbar on the Cybertruck and now the new Model Y. It’s definitely the direction Tesla is moving for all their models, so expect all future models to have it, including the new Roadster and the next-gen model.
Tesla’s Max de Zegher also took to X after the plans for the new Supercharger were found and shared the image above. He stated that Tesla wants to build a few cool Superchargers that will be worth stopping at, even if they’re out of the way a little bit. So it seems like this isn’t just a concept, but an idea that Tesla wants to expand to several areas around the country or world.
We want to build a few Superchargers cool enough to be worthy of the trip itself. Wish we could have kept it under wraps for longer, but submittal was needed for Planning Approval. We can't hide anything from @MarcoRPi1! 🙂 pic.twitter.com/X2WaKDd408
This particular site doesn't have a Megapack or other form of energy storage, unlike the upcoming Harris Ranch Supercharger site in California. That means that Tesla won’t be storing the solar energy gained from this site, but instead will be either offsetting the immediate grid impact or serving energy back to the grid when the site isn’t actively charging.
Tesla will likely be incorporating V4 Superchargers, including both V4 posts and the new, more powerful V4 Cabinets, as the permit states that Tesla will be redesigning the site internally before beginning construction. For Cybertruck owners, 500kW charging may be around the corner.
We’re hoping Tesla continues to deploy these kinds of Supercharger sites around the world - they make a stylistic statement about Tesla’s futurism, like the Shell gas station that was upcycled into a Supercharger site earlier this year in Spain.
They also make a big impact for ownership because it is a far more comfortable charging experience when you stop at a site that’s shaded from the elements - and one that’s better for the environment with offset emissions.
It was a rainy April 1st when a news-searching author went on a delve into the depths of April Fools to find fact from falsehood. And while we found a lot of fantastic jokes, we also found some good ideas.
So, with a shoutout to MarcoRP on X, whose April Fool’s Joke gave us a good run for our money for a couple of minutes, we thought to ourselves - what would a Cybercab Charging Station / Cleaning Hub really look like?
Cybercab Wireless Charging Sites
Now, before continuing, we’d like to point out that the image up top is a joke from Marco - it isn’t an accurate or real site map submission from Tesla. However, it gave us the impetus to think critically about what is required for a Robotaxi fleet, based primarily on the Cybercab, to be able to service a city.
Requirements
Tesla will likely need to charge a small fleet of Cybercabs at a single time and in a single place. That means that the site needs to be large enough to cover a major metro area while also still being compact enough to not cost too much money to build out.
In addition, we need to factor in charge times. The Cybercab is likely to launch with a battery around 50 kWh, which will result in a range of approximately 300 miles. With that much range, the average Cybercab may not need to charge more than once or at all during daytime shifts, so instead, most of the vehicles will charge overnight.
MarcoRP
Math and Charge Times
The overnight charging means that most of these vehicles could be charged slowly. When we did some back-of-the-napkin math last year, we determined that Tesla’s wireless charger will likely peak around 17 kW (for comparison, Tesla’s Wall Connector at 32 amps charges at about 7 kW). If we scale Tesla’s wireless charger down slightly to 10 kW, accounting for some energy loss and the potential size of the site, that means a Cybercab will be able to charge in about 5 hours.
Tesla’s upcoming V4 Supercharger unit can currently handle 1.5MW per cabinet, but this slower-speed charging is A/C, not DC, which means there is a step-down loss of about 3-5%. Let’s make that a comfortable 10% for any other overages, but we can estimate around 1.35MW of power. That 1.3MW will easily handle charging up to 100 Cybercabs at once - all wirelessly, using Tesla’s unique beam-forming and beam-steering technology to keep efficiency high at every single stall.
Within about 5 hours, a whole fleet of 100 Cybercabs could be charged overnight when electricity rates are cheaper and still be out in time for the morning commute.
While this is all just hypothetical, it really does make sense that Tesla will be establishing these sites that won’t require much space or a ton of energy.
Tesla recently curtained off a large section of the parking garage at Giga Texas, as well as some of their chargers on the eastern end of the facility, leading us to believe they may just be testing this at scale internally.
There’s a lot to look forward to with Tesla’s V4 Supercharger deployment coming this year and with Robotaxi launching in just a couple of months.
