Tesla may be building out a feature for vehicle-to-vehicle communication
Ian Maddox
Tesla recently wrapped up its 2022 annual shareholders meeting, and CEO Elon Musk hinted at a potentially exciting feature coming to the fleet: vehicle-to-vehicle communication.
Towards the end of the shareholders’ meeting, a gentleman in the audience mentioned how aircrafts use a system called Airborne Collision Avoidance System (ACAS). He elaborated on how ACAS relays an aircraft’s telemetry to prevent a collision.
“Sometimes too much telemetry,” Musk adds and laughs, assumingly referencing the Twitter account that tracks his private jet.
“Do you see Teslas communicating with one another and Dojo turning into some kind of air traffic control for Tesla supply chains and Robotaxi?” adds the gentleman.
Musk answered by saying he hasn’t thought about that before, which is interesting. He added that the goal with Dojo is to be the de facto computer for training the neural net with videos.
“Oh. That’s an interesting idea. I haven’t thought about that,” Musk responds. “Right now our goal with Dojo is to be really good at video training. We have probably the fourth or approaching the third, most powerful computing center in the world for AI training. Our first goal with Dojo is to make it competitive and be more effective at neural net training than a whole bunch of GPUs. We might get there… soonish.”
Musk also added that Dojo is built “from the ground up” to train AI using videos, and building such a computer has never been done before.
This question got Musk’s mind going. He paused for a moment and said there may be some difficulties in getting Teslas to communicate with one another - and it won’t be needed with Full Self-Driving.
“There will be some merits for Teslas to communicate [with] each other, but that won’t be needed for Full Self-Driving at all,” Musk responds. “But for a long time the vast majority of cars will be manually driven, so the value of Tesla-to-Tesla communication is not that high, except for, perhaps, communicating traffic issues, accidents, potholes, and road closures. A Tesla ahead of you has seen a road closure and you get that real-time update to your car so you don’t get stuck in the road closure situation. That’s the stuff that we are working on right now.”
Elon Musk's Answer
In January of 2022, Twitter user and Tesla enthusiast @BLKMDL3 tweeted at Musk asking about this type of feature. “Hey @elonmusk, can we get the air suspension in Model S/X to automatically raise quickly if the car detects a dip in the road ahead and then remember the location for next time?” BLKMDL3 writes. “Would be an awesome feature to have!”
Musk responded with, “Yeah.”
Hey @elonmusk, can we get the air suspension in Model S/X to automatically raise quickly if the car detects a dip in the road ahead and then remember the location for next time? Would be an awesome feature to have!
BLKMDL3’s tweet received quite a bit of attention.
Tesla has recently rolled out updates to improve a vehicle’s ability to raise and lower its suspension when arriving at a specific location. This is so the vehicle doesn’t scuff the pavement and cause damage to its underbody.
Since Musk stated that he hasn’t thought about vehicle-to-vehicle communication or how it would be done, we don’t anticipate this feature rolling out anytime soon. However, we can hope that it gets added to the pipeline of upcoming features due to its seemingly positive reception and want for it. This could also increase the safety of Tesla’s vehicles, even though they’re already the safest cars on the road.
It would be nice for vehicles within a 5-10 mile radius to notify one another of a construction zone, or accident, similar to Waze. This would allow the vehicle to reroute to a more efficient route or handle the situation accordingly. Going a step further, it would be exceptionally cool to see snapshots or videos of the upcoming situation by seeing a “hotspot” in maps, similar to how Snapchat shows hotspots, that are recorded via the vehicle’s cameras to more accurately prepare for it. But this may open a can of worms in regards to privacy.
Turning Tesla’s fleet into a mobile social network may go against Musk’s vision. He’s stated before that any user input in the vehicle should be considered an error, so having an interactive feature such as this may not be in Tesla’s deck of cards.

Tesla has officially announced the next major software update, 2025.26. As expected, this update will introduce the Grok AI assistant to Tesla vehicles, although it’ll initially be limited to the U.S.
Tesla also announced several other features that will arrive in update 2025.26, such as Light Sync, the ability to create and save audio presets, and others.
We’ll break down each new feature and which models and regions we expect it to be available in.
As expected, Grok will only be available on AMD Ryzen-based vehicles. Tesla says that it will also be limited to the United States and require Premium Connectivity, but it looks like it won’t require a subscription to anything else, such as Super Grok.
Unfortunately, Tesla announced that Grok will not be able to control elements in your vehicle and that the old voice command system will still be used to do that.
In a post on X, Tesla showed off Grok in action for the first time, showing the interaction between the driver and Grok. The Grok interface displays sound waves in rainbow-like colors when it’s speaking, much like another popular device. Tesla’s video of Grok is below:
Supported vehicles: Based on Tesla’s post, this is expected to include all AMD vehicles, including the Model S, X, 3, Y, and Cybertruck.
Supported regions: U.S.
Light Sync
Not a Tesla App
Tesla continues to improve the ambient light feature in Teslas by integrating it into more things. Tesla recently started using the ambient lights during Santa Mode and Rainbow Road. They also turn the ambient lighting red when you’re in Service Mode. However, this time, they’re going one step further. The ambient lights can now react to the music you’re playing by presumably changing colors based on the beat.
You’ll also have the option to maximize the brightness of the ambient lights when this feature is enabled, but only when the vehicle is parked, which Tesla is calling Rave Cave.
In addition to reacting to the music, the lights can change color to match the album color of the music being played, which is kind of similar to the ambient lights on some TVs matching the content being displayed. A needless addition? Sure. But very cool as well.
Tesla shows a screenshot of this feature, which is included in the Toybox app, and shows that you can enable or disable each feature individually, including syncing the lights to music, max brightness, and matching the album artwork color.
Supported vehicles: All vehicles with the ambient lighting feature, including the Cybertruck.
Supported regions: Assumed to be available everywhere.
Audio Settings Update
Not a Tesla App
Another feature Tesla highlights is the ability to create presets for audio settings. These audio settings will be in a new Audio tab in the vehicle’s settings, and they’ll allow you to create and save presets for different types of music. For example, you can have a preset for spoken content and another one for pop music.
Each preset will let you adjust the equalizer and set the immersive sound level.
What’s nice here is that it seems that Tesla has redesigned the audio settings and moved them to the main vehicle controls instead of only having them accessible through a button in the music player. You can see the Balance tab at the top, although it doesn’t look like you’ll be able to save the balance as part of the preset.
Supported vehicles: This is expected to be available on all vehicles, although it could exclude the legacy Model S/X.
Dashcam Viewer Updates
Not a Tesla App
This Dashcam Viewer update is only for AMD-based vehicles. It includes the ability to change the playback speed of the video being played, a feature of the old Dashcam Viewer which was surprisingly not included in the new player.
The playback speed is shown on the screen, and you’ll be able to tap it to cycle between varying speeds. The older Dashcam Viewer lets you choose between 0.5x, 1x, 1.5x, and 2x playback speeds, and this is expected to be the same in this update.
With this update, the new Dashcam Viewer also arrives on the Cybertruck for the first time, which was the only Ryzen vehicle excluded when the update was originally released.
Supported vehicles: All AMD Ryzen-based vehicles.
Supported regions: Assumed to be available everywhere.
This isn’t as exciting a feature, but it surely prevents a lot of unnecessary frustration for users who arrive at a Supercharger location only to find out it requires you to pay for parking, is only available for valet service, or has other requirements.
If the Supercharger is in a garage, Tesla will now include the floor or level number that the Supercharger is on. While there are usually physical signs at these locations, knowing the floor number the charger is on ahead of time will definitely make it easier to find.
Supported vehicles: Expected to be available on all vehicles.
Supported regions: It’s not clear whether this will be available in all regions.
Onboarding Guide
Not a Tesla App
The last feature that Tesla is highlighting in update 2025.26 is a new onboarding guide that will help new owners become familiar with their vehicles.
According to Tesla, the new guide will run through several features, such as adjusting your seat and mirrors, as well as controlling certain vehicle functions, including the lights, wipers, and Autopilot. This will be a great addition for new owners, as accessing some of these features isn’t apparent, especially if they require use of the unlabeled scroll wheel, such as activating Autopilot on newer vehicles without a stalk.
Supported vehicles: This is expected to only be available on AMD Ryzen vehicles, but Tesla doesn’t specify which vehicles it’ll be available on. Once the update starts rolling out, we should have more information.
Supported regions: This will likely be available in all or most regions.
Release Date
There may be other features included in update 2025.26 that Tesla isn’t highlighting in their post. Tesla often doesn’t include smaller additions or features that were previously introduced but have now been added to more regions.
There’s no doubt that the biggest feature in this update is Grok, but the other updates are nice improvements as well. This feature is expected to roll out to employees this weekend, and it should start rolling out to customers in the next week or two.
Tesla is moving to aggressively expand its Robotaxi Network at a rapid pace, with new information revealing that an expansion into Arizona is imminent, pending, of course, regulatory approval. Tesla has already begun looking at building out the program to other cities, just weeks after the launch of its pilot program in Austin, Texas.
Phoenix, Arizona, is Next
In a letter received following a query submitted by Sawyer Merritt, the Arizona Department of Transportation (AZDOT) has confirmed that Tesla had officially applied for Robotaxi permits on June 26th, 2025. According to AZDOT, Tesla had applied for the permits for both autonomous vehicle testing and operation with and without a safety driver.
The department also confirmed that Tesla has expressed its interest specifically in operating within the Phoenix Metro area, with a decision on the permits expected by the end of July. This is the first official step to establish Robotaxi within a second state, which is exciting to see.
Tesla Hiring Vehicle Operators
The move into Arizona isn’t an isolated event. It’s the first step in a broader national expansion, as per Tesla’s recent job postings for Robotaxi Vehicle Operators and FSD testers on Tesla’s Careers page.
These positions, which are necessary for Tesla to launch and validate the service in new locations, show us where Tesla plans to deploy Robotaxi next. The areas include:
Tempe, Arizona
Palo Alto, California
Fremont, California
San Diego, California
Henderson, Nevada
Jacksonville, Florida
Tesla is simultaneously laying the groundwork for expansion in at least three other states besides Texas and Arizona, and that’s a good sign for the network’s quick expansion. Tesla’s executive cadre pointed to a timeline of late 2025 for Robotaxi to be deployed in multiple cities across the United States, and it appears that this timeline is on track.
The Scalability Advantage
This strategy of pursuing multiple markets in parallel highlights the advantage of Tesla’s generalized autonomy approach. Because FSD is designed to be a generalized solution that learns from a global fleet, Tesla does not need to spend years meticulously pre-mapping every street in a new city.
Instead, it can target new locations and use a smaller fleet of operators to validate the performance and safety of FSD within a new environment. After all, every city has its own unique traffic regulations and environmental considerations that need to be understood.
The key here is that Tesla can turn on a fleet in a whole new location in just a fraction of the time required by other methods, such as HD mapping - which can require hundreds of mapping vehicles, thousands of hours of real humans driving, and many hours of engineering to get all the data cleaned up and ready for use.
The Austin pilot is just the beginning of Robotaxi. Tesla is already planning to expand the geofence this weekend and plans to scale the network to other cities soon.
