Tesla has released FSD Beta 11.4 to employees, with original testers hopefully soon to follow. The update is version 2023.6.15, making it the first time FSD Beta has been based on a 2023 branch. With this update, Tesla has prioritized refining the vehicle's performance over introducing new features.
Enhanced Safety Features: Pedestrians and Vulnerable Road Users
Some standout improvements include enhanced pedestrian recognition and response, allowing Tesla vehicles to predict pedestrian movements better and react accordingly. This leads to a smoother driving experience at intersections, as vehicles can accurately anticipate when to stop or proceed.
Another critical aspect of the update is its improved responsiveness to vulnerable road users, such as bikers and cyclists. The FSD Beta 11.4 update now reacts more quickly to these road users and adjusts the vehicle's speed when necessary, ensuring a safer experience for everyone involved.
Improved Driving Performance: Urban, Rural, and Adverse Weather Conditions
One of the most notable features of the update is its weather-adaptive speed control. The FSD Beta 11.4 adjusts the maximum Autopilot speed based on current weather conditions, considering factors such as visibility, road wetness, tire tread, and even tire spray from other vehicles, ensuring a safer driving experience in adverse conditions.
Urban drivers will appreciate the optimized turn performance in city environments, as the update enables Tesla vehicles to navigate dense areas and challenging turns more effectively. This results in smoother navigation while avoiding obstacles like parked cars and bus lanes. Additionally, the update brings advanced bus lane recognition, helping prevent the vehicle from accidentally entering restricted areas.
In rural areas, the FSD Beta 11.4 should improve, with upgraded lane, line, and road edge detection. This enhancement is beneficial when driving on roads with inconsistent markings and paving, providing a safer experience. Alongside these improvements, the update also refines lane guidance and partial cut-in predictions. By leveraging Tesla's extensive library of clips and auto-labelling system, these enhancements ensure the vehicle remains in the correct lane and accurately predicts the movement of other vehicles.
Smarter Navigation: Lane Guidance and Speed Adjustments
The FSD Beta 11.4 also considers upcoming navigation deadlines, adjusting the vehicle's speed accordingly during lane changes, resulting in refined lane change speed control. Furthermore, Tesla's new Vision Speed network allows its cars to infer the typical driving speed on any given roadway, optimizing speed control in various situations, such as residential areas and parking lots.
Finally, Tesla has enhanced long-range path blockage detection, enabling vehicles to merge into other lanes more swiftly to avoid obstacles on the road.
Who is Eligible for This Beta
With the latest FSD Beta being based on Tesla's 2023.6 code branch, this will make FSD Beta available to many new owners who are on a 2023.2 or 2023.6 update. So if you've been waiting to be eligible for FSD Beta before subscribing, you may soon get your chance. However, it may still take several weeks before this update, or a revision of it goes into wide release, so don't click that button just yet.
Release Date
Tesla will typically release an update to employees and then to OG testers before having it go out to everyone else in waves. However, if Tesla discovers a blocking issue, the rollout is halted until an update becomes available. Once a revision is available, Tesla will restart the rollout with employees again.
FSD Beta 11.3 went through various revisions before finally being available to most owners. However, that was a much larger update, so FSD Beta 11.4 will likely see fewer revisions. In the past we've typically seen 1 to 3 revisions before a major update to FSD Beta went into 'wide' release.
What happens next will depend on whether Tesla encounters any major issues. Tesla may release FSD Beta 11.4 to OG testers or it may be quiet for several days before 11.4.1 or a similar revision to FSD Beta surfaces.
FSD Beta 11.4 demonstrates Tesla's unwavering commitment to pushing the boundaries of autonomous driving technology, bringing us closer to a future where fully autonomous vehicles are the norm. Take a look at the release notes for FSD Beta 11.4 for a thorough look at all the changes in this update.

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.
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.
