Tesla's FSD Beta software version 11.4.6 is now available to some customers
Not a Tesla App
Tesla’s next FSD Beta update, 11.4.6 started going out to customers earlier this week, but there's a lot to discuss around Tesla's FSD software these days.
FSD Beta 11.4.6, which Tesla began pushing to employees just last week, has received positive criticism from public testers who’ve received the update. Tesla owner and influencer, Whole Mars Catalog, shared videos on YouTube showing FSD improvements, alongside commentary at locations where the software previously struggled.
All FSD Beta, All the Time
Tesla recently started including FSD Beta in all of its software updates. However, the version included is a slightly older, more stable build, known as FSD Beta 11.3.6. Having the software baked into every update means that all eligible customers can now easily activate FSD Beta simply by subscribing or buying Tesla's FSD feature. There's no longer a need to wait for Tesla to push a separate update for FSD Beta. Of course, owners will still need to be in a supported region (currently U.S., Canada) and have a supported vehicle, which unfortunately still excludes hardware 4.0 as of now.
Older FSD Beta users, on the other hand, have Tesla's older updates, version 2023.7.x, which doesn't include many of Tesla's newest features, such as the refreshed Spotify app. However, these older builds includes a newer version of FSD Beta, such as 11.4.4 or this newest build, FSD Beta 11.4.6.
Musk Says FSD V12 is “Mind-Blowing”
Tesla is working on the next milestone for FSD Beta, and in typical Musk optimism, Musk is calling this v12 alpha version, "mind-blowing."
Tesla makes significant architectural changes with each major update to FSD Beta, and v12 will be no different.
With FSD Beta v11, Tesla finally merged the city and highway Autopilot versions, which has resulted in a much smoother Autopilot highway experience, although some believe it's not as consistent or reliable. However, that's not completely unexpected with the major changes included in v11. As FSD Beta v11 matures, we'll likely gain the consistency we've become used to on our highway drives.
FSD v12 is being reserved for when the vehicle can run entirely on AI from “video in to control out,” according to Musk. This will mean that AI will finally take control of the vehicle, from steering to braking and acceleration.
Musk has a track record of being overly optimistic, but the improvements the FSD team has made in the last couple years are nothing short of amazing.
Tesla’s vehicles are its core product, but the company is also building Optimus, a human-like robot that will replace monotonous and dangerous tasks.
According to Tesla's Autopilot lead, Ashok Elluswamy, Tesla is building out its vehicle and robot software simultaneously. Many of the neural networks Tesla uses today are shared between their vehicles and Optimus, according to Elluswamy.
The closer Tesla gets to solving FSD, the closer they'll be to solving a lot of other problems. As Elon Musk has said, Tesla will likely need to solve Artificial General Intelligence in order to solve FSD. Although we're likely years away from that happening, the Tesla team isn't shying away from the challenge.

With Tesla’s first major expansion of the Robotaxi Geofence now complete and operational, they’ve been hard at work with validation in new locations - and some are quite the drive from the current Austin Geofence.
Validation fleet vehicles have been spotted operating in a wider perimeter around the city, from rural roads in the west end to the more complex area closer to the airport. Tesla mentioned during their earnings call that the Robotaxi has already completed 7,000 miles in Austin, and it will expand its area of operation to roughly 10 times what it is now. This lines up with the validation vehicles we’ve been tracking around Austin.
Based on the spread of the new sightings, the potential next geofence could cover a staggering 450 square miles - a tenfold increase from the current service area of roughly 42 square miles. You can check this out in our map below with the sightings we’re tracking.
If Tesla decides to expand into these new areas, it would represent a tenfold increase over their current geofence, matching Tesla’s statement. The new area would cover approximately 10% of the 4,500-square-mile Austin metropolitan area. If Tesla can offer Robotaxi services in that entire area, it would prove they can tackle just about any city in the United States.
From Urban Core to Rural Roads
The locations of the validation vehicles show a clear intent to move beyond the initial urban and suburban core and prepare the Robotaxi service for a much wider range of uses.
In the west, validation fleet vehicles have been spotted as far as Marble Falls - a much more rural environment that features different road types, higher speed limits, and potentially different challenges.
In the south, Tesla has been expanding towards Kyle, which is part of the growing Austin-San Antonio suburban corridor spanning Highway 35. San Antonio is only 80 miles (roughly a 90-minute drive) away, and could easily become part of the existing Robotaxi area if Tesla obtains regulatory approval there.
In the East, we haven’t spotted any new validation vehicles. This is likely because Tesla’s validation vehicles originate from Giga Texas, which is located East of Austin. We won’t really know if Tesla is expanding in this direction until they start pushing past Giga Texas and toward Houston.
Finally, there have been some validation vehicles spotted just North of the new expanded boundaries, meaning that Tesla isn’t done in that direction either. This direction consists of the largest suburban areas of Austin, which have so far not been serviced by any form of autonomous vehicle.
Rapid Scaling
This new, widespread validation effort confirms what we already know. Tesla is pushing for an intensive period of public data gathering and system testing in a new area, right before conducting geofence expansions. The sheer scale of this new validation zone tells us that Tesla isn’t taking this slowly - the next step is going to be a great leap instead, and they essentially confirmed this during this Q&A session on the recent call. The goal is clearly to bring the entire Austin Metropolitan area into the Robotaxi Network.
While the previous expansion showed off just how Tesla can scale the network, this new phase of validation testing is a demonstration of just how fast they can validate and expand their network. The move to validate across rural, suburban, and urban areas simultaneously shows their confidence in these new Robotaxi FSD builds.
Eventually, all these improvements from Robotaxi will make their way to customer FSD builds sometime in Q3 2025, so there is a lot to look forward to.
For years, the progress of Tesla’s FSD has been measured by smoother turns, better lane centering, and more confident unprotected left turns. But as the system matures, a new, more subtle form of intelligence is emerging - one that shifts its attention to the human nuances of navigating roads. A new video posted to X shows the most recent FSD build, V13.2.9, demonstrating this in a remarkable real-world scenario.
Toll Booth Magic
In the video, a Model Y running FSD pulls up to a toll booth and smoothly comes to a stop, allowing the driver to handle payment. The car waits patiently as the driver interacts with the attendant. Then, at the precise moment the toll booth operator finishes the transaction and says “Have a great day”, the vehicle starts moving, proceeding through the booth - all without any input from the driver.
If you notice, there’s no gate here at this toll booth. This interaction all happened naturally with FSD.
While the timing was perfect, the FSD wasn’t listening to the conversation for clues (maybe one day, with Grok?) The reality, as explained by Ashok Elluswamy, Tesla’s VP of AI, is even more impressive.
It can see the transaction happening using the repeater & pillar cameras. Hence FSD proceeds on its own when the transaction is complete 😎
FSD is simply using the cameras on the side of the vehicle to watch the exchange between the driver and attendant. The neural network has been trained on enough data that it can visually recognize the conclusion of a transaction - the exchange of money or a card and the hands pulling away - and understands that this is the trigger to proceed.
The Bigger Picture
This capability is far more significant than just a simple party trick. FSD is gaining the ability to perceive and navigate a world built for humans in the most human-like fashion possible.
If FSD can learn what a completed toll transaction looks like, it’s an example of the countless other complex scenarios it’ll be able to handle in the future. This same visual understanding could be applied to navigating a fast-food drive-thru, interacting with a parking garage attendant, passing through a security checkpoint, or boarding a ferry or vehicle train — all things we thought that would come much later.
These human-focused interactions will eventually become even more useful, as FSD becomes ever more confident in responding to humans on the road, like when a police officer tells a vehicle to go a certain direction, or a construction worker flags you through a site. These are real-world events that happen every day, and it isn’t surprising to see FSD picking up on the subtleties and nuances of human interaction.
This isn’t a pre-programmed feature for a specific toll booth. It is an emergent capability of the end-to-end AI neural nets. By learning from millions of videos across billions of miles, FSD is beginning to build a true contextual understanding of the world. The best part - with a 10x context increase on its way, this understanding will grow rapidly and become far more powerful.
These small, subtle moments of intelligence are the necessary steps to a truly robust autonomous system that can handle the messy, unpredictable nature of human society.
