It’s presumptuous of me to write an article on Tesla’s FSD Beta v9 considering the sad fact that my Tesla Model 3 doesn’t have it. I’ve had the urge to do it anyway, but what could I say? Well, I’ve watched videos and read articles written by people who have it, and now I have something to say that no one has said. I’m going to compare Tesla to Mercedes Benz.
There are numerous people who now have access to the FSD v9 Beta, and many of them have now posted videos online to describe their experience. We take a look at some of those most interesting videos below.
All these reviewers mention that v9 is much smoother and more human-like in its driving leading to fewer disengagements. You’ll note that even though v9 is a better driver, it’s not yet a human-level driver. There’s no such thing as disengagement when a human is driving.
AI Addict took his Tesla with v9 down Lombard St. in San Francisco and here's how it did:
For those of you not familiar with San Francisco, Lombard St is extremely curvy and hilly. It’s also very narrow. It’s a one-way street, so you have to drive downhill. The last time I drove down that hill, I scraped my car on a cement curb. AI addict went down the street twice, and he had to take over both times. Clearly, Lombard St is an edge case that the neural network hasn’t mastered yet.
Here’s a v9 video in San Francisco that doesn’t go down Lombard St, but that does still need some human interventions.
Here’s a video by Dirty Tesla in downtown Ann Arbor. He did need to intervene a number of times.
So, basically, v9 is much better than v8, but it’s still not able to drive as well as the average human driver. So, what else is new? Here’s the kicker.
There’s an article in Engadget that describes the author's test track experience in a Mercedes Benz with level 3 self-driving. Benz is planning to release level 3 within a year.
Below you have the six levels of vehicle autonomy as defined by the SAE International group, which defined the standards the US goverment now uses.
Here’s the thing about the Mercedes Benz version of level three. It’s geofenced to limited access highways, and it’s velocity fenced to speeds of less than 60 kilometers/hour which translates to speeds of less than 37.2 miles an hour. So if you buy one of these cars for the level 3 self-driving feature, you’ll be able to use it only on limited-access highways during traffic jams. According to the video, you’ll be able to watch movies, play video games, and send texts while in traffic jams, that is unless the police see you doing those things. You’ll be able to keep your hands off the steering wheel, but you still have to be ready to take over instantly if the car decides it doesn’t know what to do. If you fall asleep or raise a newspaper high enough so the interior camera doesn’t know if you’re awake and alert, the level 3 self-driving feature will stop working.
So now, let’s get back to Tesla. Although I don’t have FSD Beta v9, I do have Navigate on Autopilot on my Model 3, and that’s what gets used on limited-access highways even on cars with FSD Beta v9. So here’s my experience on limited-access highways.
I do have to keep my hands on the steering wheel, and I’m not permitted to text, play video games, or watch movies even when I’m in a slow-moving traffic jam. Frankly, I wouldn’t feel safe doing those things while driving any car including a Mercedes. And keeping my hands on the wheel seems like the right thing to do in a car that might want me to take over at any moment. It would take one or two tenths of a second for me to get my hands onto the steering wheel if they were off the wheel when an emergency situation arose. It would take one or two seconds to figure out what to do if my mind was on a text, a video game or a movie when a disengagement happened. Even a tenth of a second could make the difference between a close call and an accidental crash.
For the most part, the only time I ever need to intervene while on a limited-access road is when my Tesla and I disagree on which is the most propitious travel lane. This sort of disagreement happens often enough that I have the settings adjusted so that the car needs my consent before it changes lanes.
But if you’re willing to let your Tesla decide which lane to travel in, then Tesla FSD non-beta is already more powerful than the Mercedes level 3. Yes, you need to keep your hands on the wheel and you’re not permitted to watch movies. But otherwise, the Tesla will drive itself as well as the Mercedes, and it will do that very well at full highway speeds, in stop and go traffic jams and everything in between. Level 3 self-driving below 37 MPH isn't an improvement over advanced autopilot.
Tesla's Autopilot is currently a level two driving feature, which basically means that it should be used as an aid to drivers, but that it does not drive on your own. If you've ever used Autopilot then you'll know that Tesla is right on the cusp of level three. With the FSD Beta, I believe Tesla is planning on pushing level three automation to everyone who has purchased the FSD package. Level three is where the FSD features break free and stop just being an aid and turn into an "autonomous" vehicle that the driver should pay attention to, and not just at 37 MPH.

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.
