Tesla's Automatic Emergency Braking now works in reverse and at higher speeds
Tesla (Edited by NATA)
Tesla has made some subtle but significant changes to its owner's manual for the 2023.12 software update, revealing improvements to the Automatic Emergency Braking (AEB) system. These changes include the ability for AEB to function while the vehicle is in reverse and an increased operational speed range. The latest improvements reflect Tesla's continued commitment to enhancing the safety and performance of its vehicles.
Thanks to a reader named Randall, who brought the changes to our attention. The latest 2023.12 software update includes these improvements outlined in the updated Tesla owner's manual. Previously, the manual described AEB as being designed to reduce the impact of frontal collisions. But, as of the 2023.12 owner's manual, which was released a couple days ago, Tesla has changed this word to:
Automatic Emergency Braking is designed to reduce the impact of frontal and reverse collisions with limited functionality while in Reverse.
AEB Available at Higher Speeds
The new description in the updated owner's manual highlights a few key changes. Now, the system is designed to determine the distance from detected objects, not just those in front of the vehicle. When a collision is considered unavoidable, AEB will apply the brakes to reduce the vehicle's speed and the severity of the impact, just as before. However, the operational speed range has been increased, with AEB now functioning between approximately 3 mph (5 km/h) and 124 mph (200 km/h); it previously maxed out at 90mph (150 km/h).
AEB Recognizes Threats in Reverse and More
In addition to the increased speed range, AEB now works while the vehicle is in reverse. This new feature is expected to be available outside of Full Self-Driving (FSD) Beta and across various regions. Tesla typically specifies when a feature is limited to certain regions or requires FSD Beta, but no such limitations have been mentioned for the enhanced AEB.
These changes are in addition to the ones mentioned in the Impact Report, which included the system recognizing perpendicular threats.
The owner's manual also provides additional information on when AEB does not apply the brakes or stops applying them. These situations include:
Turning the steering wheel sharply
Pressing and releasing the brake pedal while AEB is applying the brakes
Accelerating hard while AEB is applying the brakes
The detected vehicle, motorcycle, bicycle, or pedestrian is no longer ahead
Furthermore, the manual clarifies that AEB is always enabled when starting your Tesla. To disable it for the current drive, users can touch Controls > Autopilot > Automatic Emergency Braking. It's important to note that even if AEB is disabled, the vehicle may still apply the brakes after detecting an initial collision to reduce further impact.
These updates to Tesla's AEB system are expected to improve overall safety for drivers and pedestrians alike. With automatic emergency braking now functioning in reverse and at higher speeds, Tesla continues to push the boundaries of automotive technology and safety. As always, Tesla owners should remain vigilant and attentive while driving, as no system can guarantee complete protection against collisions.

Tesla previously told its employees on the Cybertruck production line that work would be halted for three business days and that they would not be required to show up to Giga Texas for any other work. Work was halted on the Cybertruck line from December 3rd until December 6th.
Many speculated that Tesla had hit a demand mark with the Cybertruck or run into other production-related difficulties. However, pausing production for such a short period is a fairly normal business operation, as Tesla continuously retools and upgrades its production lines.
Halts for business demand tend to look more similar to Ford’s F-150 Lightning production halt - where they halted production from November 18, 2024, until January 6, 2025. Ford also announced that this production halt was due to reduced demand for its electric truck in the face of stiffer competition.
Cybertunnel
In this case, part of the reason for the halt could potentially have been due to upgrades to the underground tunnel that is used to move Cybertrucks fresh from the production line to the holding lot at Giga Texas. Tesla has been working on improving the production flow rate for its vehicle - and rather than encountering issues with production, they’ve previously mentioned they’ve had issues with getting vehicles out of their outbound parking lots and off their assembly lines - and into customers’ hands fast enough.
The Cybertunnel moves trucks from inside Giga Texas to the holding lot just outside the factory. At that holding lot, they’re either loaded into trains or trucks to be transported across North America. The tunnel passes underneath Texas Highway 130, helping to ensure that Tesla isn’t clogging up traffic crossing the highway with brand-new trucks.
More Shut Downs?
It’s likely we’ll see even more shutdowns at Giga Texas in the coming months. Tesla has shown that it intends to continue increasing production rates at Giga Texas, which means it will need time to upgrade its assembly lines and processes. In addition, the Model Y is also produced at Giga Texas—and once the Model Y Juniper arrives, there will need to be shutdowns to accommodate re-tooling.
So, no need to stress - it's just regular operations. And we get to see a cool Cyber-themed tunnel too. In the meantime, check out Joe Tegtmeyer’s drone video of Giga Texas below.

Tesla’s FSD V13 introduced a host of new features, including the ability to Unpark itself, travel in reverse, and Park at its destination. While FSD can now navigate itself out of a parking spot or garage, there are limited options when arriving at your destination, but that’s about to change.
Garage Support
Ashok Elluswamy, Tesla’s VP of AI, confirmed on X that a future revision of FSD V13 will introduce a variety of parking options, including parking in garages, driveways, parking spots, or simply pulling over on the side of the road. Drivers will presumably be able to pick when choosing a location, or maybe the vehicle will offer suggestions based on the location.
This will be a big addition, as today, FSD doesn’t understand how to park in a garage or driveway. Some owners trick FSD into parking in their driveway by using tape or road paint to outline parking spots.
Soon, that may not be necessary, and instead, FSD will simply back itself into your garage. This feature will probably work best in larger garages—extremely tight garages may not work, given the reduced precision of vision at extremely close distances.
We hope that if Tesla introduces this feature, they’ll sell printable guides you can stick on the garage walls or floor to help ensure your vehicle is in the perfect spot every time. Many commenters mentioned that they park in urban/suburban garages with only inches to spare around their vehicles, so this will be an interesting challenge for Tesla to address.
Parking Garages
Parking garages offer their own unique problem set. For the most part, FSD can already navigate its way out of a parking garage, assuming that there aren’t any special gates or sequenced/signaled signage.
It is also able to find a parking spot in multi-level garages and navigate its way out. More support for multi-level parking garages is coming, as FSD seems to stick to the garage walls until it can find the exit itself. It seems that Tesla’s data gathering and vehicle-to-fleet communication could aid Tesla in figuring out parking garages in terms of knowing the entrances and exits.

In the Upcoming Improvements section of FSD V13, Tesla mentions that more destination options will be supported, including pulling over (at the side of the road) and parking in a spot, driveway, or garage.
These other destination options are going to be important soon - because one of the biggest FSD features we’re all still waiting for is Banish AutoPark. Once your vehicle can pull over at the entrance of a location and then go park itself, we’re going to be super close to Unsupervised FSD becoming a reality.
