FSD is as big of a topic as ever for Tesla right now. Tesla is releasing betas every two to three weeks and making some of the biggest improvements to FSD it has ever made in its history. Navigate on Autopilot for highways was a big deal, but this is absolutely monumental.
Tesla has been testing their FSD Betas to a closed group of testers, but is now nearing the point where they’ll be able to expand it to a wider audience.
As we’re getting closer to the release of 10.1, Elon is releasing additional details on how users will be able to request access to the 10.1 beta.
Previously Elon talked about how Tesla owners will be able to tap a ‘Download FSD Beta’ button to request access to the beta and Tesla would then gradually allow more owners into the beta.
Good feedback from FSD Beta 10 users! 10.0.1 point release rolling out now.
10.1 rolls out a week from Friday with beta request button.
Elon is now releasing additional information on how this process will work. Elon said on Twitter that "10.1 rolls out a week from Friday with the beta request button". It sounds like the beta request button will roll out on September 24th and version 10.1 of the FSD Beta will remain on track for October 1st.
Tesla often phases in software updates to their fleet, so it’s unlikely at this point that everyone will get an update that will add a button to opt-in to the FSD Beta. Tesla has either already included the ability to display the button in previous software releases and just needs to enable it over an over the air update, or the button is not something that will be in the car. It could be a request made in the app or on their website.
How Tesla Will Decide
Elon also talked about how Tesla will decide who is let into the beta. He says that pressing the FSD Beta button will request permission to assess your driving behavior using the Tesla insurance calculator. I don’t believe Elon is saying Tesla insurance will need to be available in your state in order to qualify, but instead that Tesla will use the algorithms they use for Tesla insurance to determine a “good” driver to also assess whether you’d be a good fit for Tesla’s FSD Beta.
He goes on to say that your driving behavior will need to be in good standing for seven days before beta access is granted. It sounds like this this won't apply retroactively, but instead from the moment you request access to the FSD Beta. Since the button is going to be available on September 24th, it'll give Tesla a week to monitor your driving before giving you access to the beta on October 1st.
Beta button will request permission to assess driving behavior using Tesla insurance calculator. If driving behavior is good for 7 days, beta access will be granted.
At this point, we’re just two weeks out from the release of the 10.1 beta. And with Elon releasing additional details on how to get into the beta, I’d say Tesla is feeling very confident in its ability to deliver. Of course, we should all take it easy on Elon if dates slip a little, this is unmarked territory and we’re lucky Elon shares as much information as he does about Tesla’s future plans.
Elon also shared some news on when he expects Tesla to expand the FSD Beta outside of the US. He said that the technology will probably be ready in a few months, but ultimately will depend on regulations. I think a lot of this will depend on how the release of the FSD Beta goes in the US. If it’s smooth then Tesla will have more resources to focus on expansion outside of the US. It’s possible that depending on a country’s similarities to US roads, traffic signs etc, it could also speed up or slow down the FSD Beta’s release in the given country.
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
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.
Updated Dashcam Viewer
These vehicles are also receiving an improved Dashcam Viewer, which now displays the six camera feeds along the bottom and a new grid view that allows you to view four cameras simultaneously. 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.
We have confirmed that Tesla is only adding the additional camera recording 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.
Update: Tesla is including the new Dashcam viewer for Ryzen vehicles.
New Dashcam Viewer is Available on HW3 / Ryzen Vehicles
Tesla doesn’t include the new Dashcam Viewer as a feature in the 2025.14.3 release notes, but owners with Ryzen-based HW3 vehicles are receiving the improved Dashcam player. However, they’re only receiving the improved player, not the B-pillar camera recording. The new player is a worthy addition, so it’s great to see Tesla include this feature even if B-pillar recording isn’t possible.
The new player includes four improvements:
New grid view that lets you view four cameras at the same time
Different camera views, including the grid view are spread out across the bottom instead of at each corner
You can jump back and forward in 15-second increments
Users can jump to the next Sentry Mode video by tapping the button on the top right corner, making it easier to jump to the next event instead of having to go back to the list of events.
The existing functionality remains largely intact, including the ability to jump to a Sentry Mode event. However, the playback speed selection of 0.5x, 1x, and 2x has been removed.
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.
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
The 46 new MCS sites coming soon.

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.
