Tesla is improving a crucial safety feature to Media Control Unit 1 (MCU1) vehicles in a new update, giving cars with an older manufacturing date access to what is a relatively standard crash avoidance feature on vehicles built within the last few years.
The MCU1 came standard on Model S and Model X vehicles from 2013 to 2018, but has been getting some routine upgrades as of late.
Tesla’s aim is to make some of its legacy vehicles more robust with a variety of new features, giving early adopters and those who purchased older cars for a good price a touch of the company’s modern technology.
Perhaps the most recent feature Tesla has added is one of the more well-rounded safety additions to any vehicle, as the automaker has upgraded and improved Automatic Emergency Braking (AEB) to MCU1 vehicles.
According to Not a Tesla App, Tesla has added AEB for speeds of 100 MPH or more and AEB in reverse. Tesla originally added AEB to MCU1 vehicles in the 2023.12 software update late last year but has bolstered its performance with the addition of two more features that make it slightly better than what is considered standard.
NHTSA releases AEB system requirements to be implemented by 2029
Tesla said in the release notes:
“Automatic Emergency Braking now also works when your vehicle is in Reverse (R), not only in Drive (D). It applies the brakes if the vehicle detects an object in its path and a collision appears imminent. Automatic Emergency Braking is on by default each time you drive.”
While unconfirmed, the report also states that, due to the addition of FSD v12 in MCU1 vehicles, Tesla might have included AEB to react to perpendicular vehicles. This would help with collision avoidance for someone running a red light or being cut off.
Additionally, Forward Collision Warnings (FCW) are also available with FSD v12, producing haptic, audible, and visual warnings. This, along with the perpendicular warnings, were not explicitly mentioned by Tesla in the release notes for this update. However, Tesla likely added them to MCU1 vehicles based on the rollout of FSD v12 to these older vehicles.

Tesla begins Grok AI chatbot rollout to Australia and New Zealand fleet
The update follows earlier deployments in the United States and Europe.
Tesla has rolled out its Grok AI assistant to Australia and New Zealand, embedding the conversational chatbot directly into compatible vehicles via an over-the-air update.
The system, developed by Elon Musk’s xAI, is now live on select models, giving drivers access to a voice-based assistant that goes well beyond traditional command-driven controls.
The update follows earlier deployments in the United States and Europe.
Tesla Australia confirmed Grok is available on Model S, Model 3, Model X and Model Y vehicles equipped with an AMD processor and running software version 2025.26 or later.
“Grok is coming to Teslas in Australia and New Zealand. It can answer almost any question using real-time information & also add/edit navigation destinations to become your personal guide. Phased rollout has now begun to eligible vehicles,” Tesla Australia and New Zealand wrote in a post on its official X account.
Drivers can activate Grok using the steering wheel controls once the update is installed. Access requires either a Premium Connectivity subscription or a stable Wi-Fi connection.
Unlike conventional in-car voice assistants that rely on fixed prompts, Grok is designed to respond conversationally. It can adjust navigation mid-trip, locate nearby points of interest, explain dashboard warnings, provide driving guidance and reference the owner’s manual.
Tesla noted that interactions with Grok are processed by xAI and remain anonymous to Tesla, adding that conversations are not linked to a specific driver or vehicle.
Grok has attracted attention overseas for offering multiple interaction modes. In the U.S., users can select personalities such as Assistant, Language Tutor, Therapist, Storyteller and Meditation. Additional optional modes for adult users include settings labeled Unhinged, Motivation, Argumentative, Romantic and even Sexy.
Viral clips shared online have shown Grok adopting sarcastic or playful tones that differ from more neutral digital assistants, with the AI assistant typically catching drivers off-guard with its sharp personality and wit.

Ford is charging for a basic EV feature on the Mustang Mach-E
When ordering a new Ford Mustang Mach-E, you’ll now be hit with an additional fee for one basic EV feature: the frunk.
Ford is charging an additional fee for a basic EV feature on its Mustang Mach-E, its most popular electric vehicle offering.
Ford has shuttered its initial Model e program, but is venturing into a more controlled and refined effort, and it is abandoning the F-150 Lightning in favor of a new pickup that is currently under design, but appears to have some favorable features.
However, ordering a new Mustang Mach-E now comes with an additional fee for one basic EV feature: the frunk.
The frunk is the front trunk, and due to the lack of a large engine in the front of an electric vehicle, OEMs are able to offer additional storage space under the hood. There’s one problem, though, and that is that companies appear to be recognizing that they can remove it for free while offering the function for a fee.

Ford is charging $495 for the frunk.
Interestingly, the frunk size varies by vehicle, but the Mustang Mach-E features a 4.7 to 4.8 cubic-foot-sized frunk, which measures approximately 9 inches deep, 26 inches wide, and 14 inches high.
When the vehicle was first released, Ford marketed the frunk as the ultimate tailgating feature, showing it off as a perfect place to store and serve cold shrimp cocktail.
Ford Mach-E frunk is perfect for chowders and chicken wings, and we’re not even joking
It appears the decision to charge for what is a simple advantage of an EV is not going over well, as even Ford loyal customers say the frunk is a “basic expectation” of an EV. Without it, it seems as if fans feel the company is nickel-and-diming its customers.
It will be pretty interesting to see the Mach-E without a frunk, and while it should not be enough to turn people away from potentially buying the vehicle, it seems the decision to add an additional charge to include one will definitely annoy some customers.

Tesla to improve one of its best features, coding shows
According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.
Tesla is looking to upgrade its Matrix Headlights, a unique and high-tech feature that is available on several of its vehicles. The headlights aim to maximize visibility for Tesla drivers while being considerate of oncoming traffic.
The Matrix Headlights Tesla offers utilize dimming of individual light pixels to ensure that visibility stays high for those behind the wheel, while also being considerate of other cars by decreasing the brightness in areas where other cars are traveling.
Here’s what they look like in action:

As you can see, the Matrix headlight system intentionally dims the area where oncoming cars would be impacted by high beams. This keeps visibility at a maximum for everyone on the road, including those who could be hit with bright lights in their eyes.
There are still a handful of complaints from owners, however, but Tesla appears to be looking to resolve these with the coming updates in a Software Version that is currently labeled 2026.2.xxx. The coding was spotted by X user BERKANT:

This is a major step beyond current adaptive high beams.

Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.
Finally, the new system will prevent the high beams from glaring back at the driver. The system is made to dim when it recognizes oncoming cars, but not necessarily objects that could produce glaring issues back at the driver.
Tesla’s revolutionary Matrix headlights are coming to the U.S.
This upgrade is software-focused, so there will not need to be any physical changes or upgrades made to Tesla vehicles that utilize the Matrix headlights currently.
