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.

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 lands regulatory green light for Robotaxi testing in new state
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.
Tesla has landed a regulatory green light to test its Robotaxi platform in a new state, less than three months after the ride-hailing service launched in Texas.
Tesla first launched its driverless Robotaxi suite in Austin, Texas, back on June 22. Initially offering rides to a small group of people, Tesla kept things limited, but this was not to be the mentality for very long.
It continued to expand the rider population, the service area, and the vehicle fleet in Austin.
The company also launched rides in the Bay Area, but it does use a person in the driver’s seat to maintain safety. In Austin, the “Safety Monitor” is present in the passenger’s seat during local rides, and in the driver’s seat for routes that involve highway driving.
Tesla is currently testing the Robotaxi platform in other states. We reported that it was testing in Tempe, Arizona, as validation vehicles are traveling around the city in preparation for Robotaxi.

Tesla is also hoping to launch in Florida and New York, as job postings have shown the company’s intention to operate there.
However, it appears it will launch in Nevada before those states, as the company submitted its application to obtain a Testing Registry certification on September 3. It was processed by the state’s Department of Motor Vehicles Office of Business Licensing on September 10.

It will then need to self-certify for operations, essentially meaning they will need to comply with various state requirements.
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.
CEO Elon Musk has stated that he believes Robotaxi will be available to at least half of the U.S. population by the end of the year. Geographically, Tesla will need to make incredible strides over the final four months of the year to achieve this.
Tesla is set to improve a critical feature that has not been present in older vehicles with a new update.
Tesla vehicles feature a comprehensive suite of driver assistance features, some of which aid in driving itself, while others support the vehicle’s surroundings.
One of those features is that of Driver Visualization, and with the rollout of a new update, owners of Intel-based Tesla vehicles are receiving an upgrade that will come with a simple software update.
Tesla plans to use Unreal Engine for driver visualization with crazy upgrade
The update will provide new visualizations while Intel-based vehicles are in reverse, a feature that was not previously available, but will be with Software Update 2025.32.2.
The improvement was spotted by Not a Tesla App via TheBeatYT_evil:
Noticed something new in 2025.32.2 on my Intel MCU + USS car with FSD.
When shifting into reverse, the full FSD visualization now stays on instead of switching to the old plain autopilot visuals.

Previously, vehicles Tesla built were equipped with Intel-based processors, but newer cars feature the AMD chip, which is capable of rendering these visualizations as they happen. They were capable of visualizations when driving forward, but not in reverse, which is what this change resolves.
It is a good sign for those with Intel-based vehicles, as Tesla seems to be paying attention to what those cars are not capable of and improving them.
This was an undocumented improvement associated with this particular update, so you will not find any mention of it in the release notes that Tesla distributes with each update.

Tesla looks to make a big splash with Robotaxi in a new market
Tesla has been transparent that it is prioritizing safety, but it believes it can expand to basically any geographical location within the United States and find success with its Robotaxi suite. CEO Elon Musk said it could be available to half of the U.S. population by the end of the year.
Tesla is looking to make a big splash with Robotaxi in a new market, as the company was spotted testing validation vehicles in one region where it has not yet launched its ride-hailing service.
After launching Robotaxi in Austin in late June, Tesla followed up with a relatively quick expansion to the Bay Area of California. Both service areas are operating with a geofence that is expansive: In Texas, it is 173 square miles, while in the Bay Area, it is roughly 400 square miles.
Tesla has been transparent that it is prioritizing safety, but it believes it can expand to basically any geographical location within the United States and find success with its Robotaxi suite. CEO Elon Musk said it could be available to half of the U.S. population by the end of the year.
There have been plenty of reports out there that have speculated as to where Tesla would land next to test Robotaxi, and Nevada, Florida, Arizona, and New York have all been in the realm of possibility. These regions will need to approve Tesla for regulatory purposes before Robotaxi can officially operate.
Tesla is still testing and performing validation in several regions, and in Tempe, Arizona, things are moving forward as a Model Y with a LiDAR rig was spotted performing ground truth for the platform:

With the LiDAR unit, many followers of the self-driving and autonomy space might wonder why Tesla uses these apparatuses during validation, especially considering the company’s stance and vision-based approach.
LiDAR is used for “ground truth,” which is basically a solidification or confirmation of what the cameras on the car are seeing. It is a great way to essentially confirm the accuracy of the vision-based suite, and will not be used on Robotaxi units used within the ride-hailing suite.
The Robotaxi platform was made available to the public earlier this month, as Tesla launched its app for iOS users.

Downloading the app allows you to join a waitlist, giving you the opportunity to utilize and test the Robotaxi platform in either Austin or the Bay Area.
