With FSD V12.4.1 finally beginning its rollout to select customers as of last night. You’re probably wondering exactly how nags will – or won’t – work for the updated and much-hyped update.

No Steering Wheel Nags

Tesla’s current implementation of no steering wheel nags on V12.4.1 is pretty simple and straightforward. As long as you’re paying attention and looking at the road, you won’t be required to touch the steering wheel. You’ll see a green dot on the screen, letting you know that the enhanced driver monitoring system (DMS) and Vision-Based Attention Monitoring (VBAM) are active.

On the Model S and X, the green dot is on the instrument cluster screen, immediately next to the blue FSD/AP wheel icon. On the Model 3 and Model Y (and Cybertruck, in the future), the green dot indicator is on the top left of the screen, in between the battery indicator and the blue FSD/AP wheel.

However, there are some restrictions baked into this initial implementation. Your eyes cannot be obscured or occluded from the cabin camera. This means that legacy vehicles are ineligible for the new VBAM, along with anyone who installs a physical camera cover for privacy or other reasons.

For the privacy-conscious folks, Tesla has mentioned that cabin camera imagery will not leave the vehicle itself unless you enable data sharing, which is optional. Cabin camera imagery is also not available to view via the API, so third-party integrations cannot view your cabin camera either.

Restrictions

There are some other catches too. The cabin camera is currently unable to see through sunglasses due to the polarization. The car will display “Attention monitoring unavailable, sunglasses use detected” on the screen. This could change in the future as Tesla figures out how to best take advantage of its cabin cameras. However, it can see through regular glasses just fine – so eyeglass wearers, rejoice!

Vehicles that do not have IR lights in the cabin will also not be able to take advantage of VBAM at night – as the cameras in vehicles without IR lights are unable to see at night. Tesla does offer a refit for vehicles to upgrade to IR-capable cameras – put in a service ticket if you’re interested through the Service Menu on the app.

If it cannot find your eyes due to any of these restrictions, the green light will not come on, and the regular wheel nags that you are used to will continue.

Warnings and Suspensions

If VBAM determines that you’re not paying attention – initially a screen warning will appear, telling you to pay attention to the road. This can be dismissed quickly by just reverting your attention to the road ahead of you. You won’t have to touch the steering wheel to dismiss the nag.

However, if you continue to not pay attention and the DMS detects improper usage, you will receive an Autopilot Strikeout, and FSD will disengage. Before a Strikeout occurs, there will be multiple auditory and visual warnings, ensuring you have a few moments to bring your attention back to supervising FSD.

You can receive up to 5 Strikeouts before the FSD becomes suspended. One strikeout will be lifted per 7-day period in which you do not receive a Strikeout. If you hit 5 Strikeouts, it could be up to 5 weeks before you clear all of them! If you receive another Strikeout within that 7-day period after an initial Strikeout, the 7-day period is reset.

Other Changes

Elon Musk has mentioned that V12.4 was supposed to be focused on user comfort, by reducing hard acceleration and braking. According to Musk, it should have a 5-10x improvement between user disengagements.

Early Access owners have mentioned that 12.4 tends to be more assertive and less hesitant when it comes to intersections, stop signs, and parking lots. Owners have also noticed improvements in the “lane dancing”, where FSD V12.3 would stray in between lanes for too long while changing lanes.

Of additional note is that Vision Autopark is slightly faster – but this is the same Vision Autopark speed increase that rolled out to customers who have already received the Spring Update. For everyone else, expect a 2-3x improvement in how fast Vision Autopark changes directions, and how fast it maneuvers in general. As of the Spring Update, it can now park in even tighter spaces.

Another much-appreciated feature is the ability to temporarily increase the sensitivity of Autowipers. As many have experienced, the Autowiper functionality doesn’t always work well. However, with the Spring Update, you can now temporarily increase the sensitivity of the Autowiper system by tapping once on the wiper stalk (or button on stalkless vehicles).

Missed Features

Sadly, some previously announced features were missed out on in this release of FSD V12.4.1. Namely, the key features of Banish Autopark and Park Seek. For the time being, users will still have to disengage FSD and then engage Autopark once they find their parking spot.

Banish Autopark, or “Reverse Summon” was thought to arrive in V12.4 as part of the comfort update according, allowing you to choose a parking spot type preference, exit the vehicle, and then have the car park itself.

Additionally, Park Seek – which would allow FSD to automatically find a parking spot in a parking lot, and then engage Autopark automatically, was initially a confirmed feature, but is not present in this release.

Finally, Hand Gesture recognition was supposed to come in an update “later in May” – but given that FSD V12.4 has missed previous deadlines – no surprise to people familiar with the “2 week policy” – there is no confirmation yet if that feature has made it into this build. It is very possible that the employee in question may have been referring to V12.5 – which is also expected to bring vehicle-to-fleet communication.

Expected Wide Release

Given that it just rolled out to employees yesterday, and then to “OG” FSD Beta owners today, we could expect 2024.15.5 – the version that contains V12.4.1 – to hopefully continue rolling out to customers next week. Everyone with an update under 2024.15.5 - so users on 2024.3.252024.8.9, and 2024.14.11 – should be eligible to receive this update. The very few vehicles already on 2024.20 with the Adaptive Headlights functionality will have to wait a bit longer!

Tesla Semi Keynote: New Features, 46 Charging Sites, Upgraded Battery & More [VIDEO]

Tesla’s Dan W Priestley attended the Advanced Clean Transportation (ACT) Expo in Anaheim, California, and provided an update on Tesla’s Semi truck program. The presentation covered several key developments on the status of Tesla’s Nevada Semi Factory, refinements to the Semi, and Tesla’s plans for charging and ramping production through 2026.

Let’s dig in and take a look at everything that was captured by the Out of Spec team at ACT Expo. The original video is embedded below if you’d like to watch it.

Semi Factory & Production Ramp

Priestley reaffirmed the timelines mentioned during Tesla’s Q4 2024 Earnings Call that Tesla will scale Semi production in 2026. To achieve this, Tesla has been actively building and expanding the Gigafactory Nevada site, specifically to support the production of the Tesla Semi. The dedicated Semi facility will have a targeted annual capacity of 50,000 Semi trucks.

Following the beginning of production, Tesla will utilize the initial trucks to integrate into its own logistics operations. This will serve as both a final real-world testing ground as well as an opportunity for Tesla to gather data internally. Tesla plans to begin subsequent customer deliveries throughout 2026 as the ramp-up continues.

Reuters also reported that Tesla is hiring over 1,000 new employees at the Semi Factory to begin the rapid ramping of the program.

Semi has already amassed 7.9 million miles with Tesla’s current testing and operational fleets, providing some real-world data and testing. Feedback for the truck has been exceptionally successful, with many drivers praising the Semi’s performance and comfort.

New Tesla Semi Features

Of course, it wouldn’t be a Tesla keynote without showing off some new things. The Semi will be available in 500-mile and 300-mile range configurations, now featuring updated mirror designs and a drop-down glass section to improve visibility and allow easier interaction with external elements—such as control panels at ports, for example.

New Electric Power Take-Off (e-PTO)

The Tesla Semi will also feature a new capability called Electric Power Take-Off, or e-PTO system. Similar to the PTO systems found on other vehicles, this will allow the Semi’s high-voltage battery to power auxiliary equipment at variable voltages. That includes being able to power things like climate-controlled reefer trailers, potentially replacing the noisy and polluting diesel generators traditionally used for this purpose.

Charging and Batteries

Tesla is also working on an updated battery pack design for the final production design of the Semi. This new pack is designed to be more cost-effective to manufacture. The battery pack itself is slightly smaller than before, but the truck maintains the same level of range through efficiencies. Dan also confirmed during his keynote that the battery cells for the Semi will be sourced domestically inside the United States, helping to alleviate potential burdens due to tariffs.

On the charging front, Tesla is using MCS - the Megawatt Charging System - capable of 1.2MW - and designed specifically for Semi. The system uses the same V4 charging hardware found at Supercharger sites but focuses on that larger power output. Alongside a smaller physical footprint, Tesla will be able to configure these V4 cabinets for either dedicated Semi charging or for shared power scenarios with regular Superchargers. Tesla is also working on an integrated overnight charging product, but Tesla isn’t ready to talk about it yet.

46 Semi Charger Sites Coming

Finally, Tesla has made substantial investments in a public charging network for the Semi. There are currently 46 sites in progress throughout the United States, and plans for significant expansion throughout 2026 and 2027. These sites are strategically located alongside major truck routes and within industrial areas to support long-haul and regional operations. Tesla is aiming to offer the lowest possible energy costs to operators to help incentivize adoption.

This was one of the best updates to the Tesla Semi we’ve received since its initial unveiling. It seems that the Semi will receive a big portion of Tesla’s attention in 2026, while Robotaxi and FSD Unsupervised take the stage this year.

The Tesla Semi has the potential to transform transportation even more dramatically than EVs already have, serving as a testament to Tesla’s mission to electrify the world.

Tesla’s B-Pillar Sentry Mode Recording Requires HW4, Not Just Ryzen — Breakdown of Spring Update Requirements

By Karan Singh
Not a Tesla App

Sentry Mode is an invaluable tool for owners - capable of keeping the vehicle safe and secure even when you’re not around. This is especially true in recent times, with the misguided and unfortunate incidents surrounding Tesla ownership, including damage to Tesla vehicles, showrooms, and Superchargers.

B-pillar Camera Recording and Dashcam Viewer

With the 2025 Spring Update on 2025.14, Tesla is expanding Sentry Mode’s functionality for certain vehicles with some much-needed changes. Sentry Mode and Dashcam can now record footage from the vehicle’s B-pillar cameras. These cameras are located on the side pillars of the vehicle, between the front and rear doors.

This adds two crucially needed viewpoints, making Tesla’s Sentry Mode a truly 360-degree security system. These cameras also provide the best angles for capturing license plates when parked, so they will be greatly appreciated by owners in the event of an incident.

These vehicles are also receiving an improved Dashcam Viewer, which now displays the six camera feeds along the bottom and a new grid view. It also allows users to jump back or forward in the video in 15-second increments.

However, to the disappointment of many owners, not all vehicles are receiving these updates due to the additional processing power needed.

Limited to Hardware 4 Vehicles, Ryzen Isn’t Enough

We have confirmed that Tesla is only adding the additional camera recording and improved Dashcam Viewer on hardware 4 (HW4 / AI4) vehicles. The newer hardware presumably has the additional processing power and bandwidth needed to handle recording and saving the two additional video streams during Sentry Mode and Dashcam.

For the time being, owners of HW3 vehicles are not receiving this feature. This includes all vehicles with HW3, even those with AMD Ryzen infotainment systems. If you’re not sure whether your vehicle has HW3 or HW4, you can refer to our FSD hardware guide.

While there’s no doubt that recording two additional camera streams would be more computationally intensive, we hope that Tesla adds the improved Dashcam Viewer to HW3 vehicles in a future update.

Cybertruck Also Missing Improved Sentry Mode

Surprisingly, and most confusing for many - is the fact that the Cybertruck is also not receiving the improved Dashcam Viewer and B-pillar camera recording with this update. This struck us as odd, especially since the Cybertruck is currently the only vehicle with the improved, more efficient version of Sentry Mode.

Every Cybertruck is equipped with HW4 and AMD Ryzen infotainment units, so this clearly isn’t a hardware restriction. It’s possible the more efficient Sentry Mode is playing a role here due to the infrastructure changes. However, we expect Tesla to address this in a future update and eventually release these features for the Cybertruck as well.

Given the Cybertruck’s high visibility and its status as a frequent target for both positive and negative attention, many owners hoped that the Cybertruck would be one of the vehicles to receive this feature.

Adaptive Headlights

Tesla finally started rolling out its adaptive headlights in North America. While the new Model Y already came with the feature when it was released last month, other vehicles with matrix headlights are now receiving the feature in the Spring Update.

All vehicles with matrix headlights are receiving this feature, which includes the new and old Model 3, first-gen Model Y, and the new Model S and Model X.

If you’re not sure if your vehicle includes matrix headlights, check out our guide. What’s interesting here is that older vehicles that were retrofitted with matrix headlights due to an accident or user replacement are also receiving the adaptive headlights feature.

Legacy Model S & Model X

As with most updates, the older legacy Model S and Model X are not receiving all the features included in this update. Unfortunately, some of the features, which include the Blind Spot Camera on the instrument cluster, Save Trunk Height Based on Location and Keep Accessory Power On are limited to the new Model S and X.

Legacy S and X models will receive the Alternative Trip Plans feature, Avoid Highways (Requires Intel MCU) and the Keyboard Languages feature.

These vehicles are also receiving all the features in the Minor Updates section except for the visualization showing how far the door is opened, which is exclusive to the Cybertruck. These additions include improved music search results, contact photos in the phone app, automatic connecting to hotspots, the ability to show third-party chargers, view Supercharger amenities, and various improvements to music services.

While many users will be disappointed not to receive the B-pillar camera recording and Dashcam Viewer improvements, it’s important to remember that Tesla typically does a great job at bringing features to older vehicles, at least with the Model 3 and Model Y. If a feature isn’t added, it’s usually due to a hardware limitation.
