Tesla FSD V12.5.5 Adds End-to-End Highway Stack; Tesla Teases Upcoming Features

Not a Tesla App

Tesla has launched FSD V12.5.5 with update 2024.32.20, which has just hit early access testers. This update includes several new things, including the new end-to-end highway stack and bringing FSD to the Cybertruck for the first time. Tesla also outlined additional features to expect in future revisions of FSD.

The End-to-End part of the stack means that rather than hand-coding all the decision-making directly into FSD, Tesla now relies upon AI, trained upon hundreds of thousands of hours of footage gathered by its fleet, to make decisions.

This is key to rapid improvements and will help to bring Unsupervised FSD – and Robotaxi – to realization. We’re especially excited to see these improvements with the Robotaxi event just around the corner.

End-to-End Highway Stack

FSD V12 brought the End-to-End stack to City Streets, and the Highway Stack was still running FSD V11. With this update, end-to-end AI will now be used on the highway, which should be a considerable improvement.

When End-to-End was introduced on city streets, it brought some drastic improvements in how FSD was handled between V11.4.9 and V12.3.6. There’s likely going to be a similar level of improvement between FSD V12.5.4 on the highway and FSD V12.5.5 on the highway.

As of today, FSD still tends to sit in the left lane, Auto-Speed doesn’t function on the highway, and the speed limit can change drastically where it's incorrectly mapped.

With the end-to-end highway stack, we could see FSD correctly use the left lane to overtake vehicles and then come back into the middle or right lane, as required. In addition, we could see Tesla add Auto-Speed functionality for the highway so that the vehicle is able to more fluidly respond to changes in traffic and speed more naturally.

Upcoming Improvements

In the release notes for FSD 12.5.5, Tesla also updated the list of features coming in future FSD versions, some of which Tesla hadn’t previously discussed or mentioned in the FSD Roadmap. In Tesla’s release notes, they specifically mention these upcoming improvements:

• Earlier and more natural lane change decisions

• Improved performanec in parking lots

• Improved performance at intersections and stops

• Introduction of Speed Profile

Earlier and More Natural Lane Changes

First off, Tesla mentions earlier and more natural lane change decisions. We’ve seen this one pop up before, and it's definitely a pain point for Tesla. Even today on FSD V12.5.4, FSD will still sometimes make lane change decisions within less than 200 feet of a turn, moving you from the far right to the left turning lane in a short space.

Addressing this will greatly help how smooth FSD will feel.

Improved Performance in Parking Lots

Tesla also mentions improved parking lot performance as coming soon. This particular enhancement to FSD will likely help improve Actually Smart Summon so that it can expand beyond FSD-specific updates and become available to more users. This will allow users with Enhanced Autopilot and owners outside of North America to gain access to Actually Smart Summon for the first time. Currently, Actually Smart Summon is available to users in North America with 2024.27.25.

In addition, we’re expecting Banish – also known as Reverse Summon – to rely upon these improvements. Banish will allow your vehicle to drop you off at an entrance to a location, and then find a parking stall, and park itself. This is going to be another key item for Robotaxi and Unsupervised FSD and is one of the items we’re the most excited about.

Improved Performance at Intersections and Stops

FSD V12.5 brought along some oddities regarding intersections. Owners have been reporting FSD stopping for green lights or double braking on stop signs. This feature is likely to target some of these existing issues.

While FSD V12.5 also brought pretty drastic improvements for roundabouts, there are still some issues with signalling and lane selection in multi-lane roundabouts, so maybe they’ll address those here as well. This is a pretty broad category, so we can only imagine what they’ll be doing here.

Introduction of Speed Profile

We previously reported that Elon Musk wanted to add a new FSD drive mode. It appears that FSD’s Assertive Mode will become “Hurry Mode.” However, based on the release notes, Tesla seems to imply that it may not be called Hurry Mode but instead Speed Mode. This mode will likely be an option that tells FSD to go a bit faster and also become more aggressive with overtaking – something that has become more common and much smoother with FSD V12.5. This is going to be an interesting addition or change, and we’ll be sure to dig into it more in the future when it becomes available.

Release Date

Tesla’s Autopilot director Ashok Elluswamy posted on X that while the Cybertruck is receiving FSD 12.5.5 with the end-to-end highway stack, don’t expect it to roll out to other vehicles immediately. Tesla prioritized getting this out for the Cybertruck and they’re still working on getting the highway stack ready for other vehicles. Ashok said that he expects Tesla to have an internal build ready in about a week or so. With Tesla’s robotaxi event just 10 days out, it sounds like this won’t arrive on customer vehicles until after the event.

Great job by the @Tesla_AI team on meeting the goals laid out for September🤩

End-to-end on the highway is first shipping to Cybertrucks. We are close to an early release build for remaining platforms and will release to internal employees in the next week or so.

First Look at Tesla’s New 'Blind Spot While Parked' Feature [VIDEO]

Automobile Propre

Tesla software update 2024.44.3 has started rolling out to customers in larger waves recently and it brings several new features - including Actually Smart Summon to Europe and the Middle East, as well as improvements to Autopark. But that’s not all, it also adds a new Blind Spot Monitoring feature to the new Model 3, and potentially the Cybertruck, but that’s still to be determined.

We previously covered the Blind Spot Warning While Parked as part of our preview notes for update 2024.44, but now that it's going out to customers, it's time to see it in action.

Blind Spot Monitoring While Parked

If the vehicle’s door open button is pressed, and a vehicle or object is near or incoming, the vehicle’s Blind Spot Warning Light (2024 Model 3 and Cybertruck) will illuminate, an audible tone will ring and the door won’t open. A message will also be displayed on the center displaying, letting driver’s know why the door didn’t open.

Pressing the button a second time will allow you to override the warning and open the door normally, providing a way to get out in case you just parked close to a nearby vehicle or obstacle.

The object detection for this new feature includes cars, pedestrians, cyclists, and other objects - like things including traffic cones, bollards, strollers, and other large obstacles that FSD and vision-based Autopark detect during normal operation. Of note - this only works for the front two doors. Thanks to X user Max, who did some testing for us, It does not work for the rear passenger doors.

Optional Feature

The feature is optional - it’ll be enabled by default for safety, but if you need to enable or disable it, you can do so under Controls > Safety. For now, the feature is only available on the 2024 Model 3, but we expect it to roll out to the Cybertruck at least. However, there’s no reason why it can’t be added to other vehicles as well, minus the small red dot. We expect Tesla to eventually add this feature to all Tesla vehicles, but it’s currently not a part of update 2024.44.

Enhauto’s S3XY Buttons & Commander

If that’s not enough safety and vision for you, Enhauto, the makers of the popular S3XY Buttons and Commander recently put out a new software update for the 2024 Model 3, which makes some fantastic use of the ambient lighting.

With Enhauto’s solution, users are able to tie their ambient lights to Autopilot use, turn signals or even if a vehicle is their blind spot. Check out the video below for this awesome implementation, where the ambient lights turn red when another vehicle approaches.

Maybe Tesla will integrate something like this into a future update? We’ve been hoping for more customizability with their ambient lighting - it's an easy safety win and a demonstration of Tesla’s do-more-with-less attitude.

I look forward to @enhauto updates more than Tesla...

Ambient light effects....

I set default color to white.
Blinks green on turn signals
Turns blue on FSD activation
Yellow if someone in blind spot
Blinks red if turn signal on and blind spot activity detected.

Tesla Improves Trip Planner - Arrival State of Charge Coming

DBurkland/X

Tesla recently added the ability to report Supercharger issues - such as insufficient lighting, accessibility, cleanliness, and other things that can’t be automatically monitored. In response to the post on the official X Supercharger Community, Max de Zegher, Director of Charging, North America, confirmed that one of the most wish-listed features - Arrival State of Charge, is coming soon.

The feature is now possible thanks to what Wes Morrill, Cybertruck’s lead engineering, points out is a huge rewrite of Tesla’s Trip Planner, which not only makes it much more accurate but will now allow users to choose their arrival charge percentage.

More Accurate Trip Planner

When you navigate to a destination, your Tesla will automatically calculate when, where, and how much you need to charge. While the process seems straightforward, Tesla deserves a lot of credit for creating a simple user experience because a lot goes into accurately determining this information.

Tesla has to calculate many moving pieces in order to accurately predict when and where you should stop. First, it needs to consider your driving efficiency and wind direction, terrain elevation, traffic, vehicle speed, and ambient temperature. It also needs to predict the best Superchargers to stop at, taking into account congestion and charger speed.

This morning, in response to Dan Burkland, Wes shared that Tesla had significantly rewritten the backend portion of Trip Planner. These improvements, made by several engineers, were designed to improve Trip Planner’s accuracy and open the door to future features.

It sounds like these changes are mostly server-side, so thanks to their OTA connection, more accurate predictions should be available to all vehicles—no vehicle update is required.

Arrival State of Charge

Along with Tesla’s improvements to Trip Planner, Wes also stated that these improvements allow for a popular feature request — the ability to select your desired charge level at arrival.

Up until now, Tesla’s Trip Planner tried to get you to your destination as quickly as possible, which usually meant arriving with a low state of charge.

While this was fine if you have a charger at your destination, it’s not great if you don’t, or it could be even worse if there are no chargers nearby.

Max de Zegher said on X that he has heard the requests for a selectable arrival state of charge. Wes later clarified this by saying that these improvements to Tesla’s Trip Planner now allow for additional features to be added, such as “desired arrival charge.”

Actually trip planner got a huge rewrite on the back end. I had a great conversation with one of the engineers working on this over a morning run a few weeks back, it's pretty neat. The rewrite also unlocks additional features, like desired arrival charge.

When Does it Arrive?

Given that Max de Zegher’s comments came last night and Wes Morrill commented this morning, this feature request likely won’t arrive with the upcoming Holiday Update. Tesla actually hinted at such a feature being added in their last app update, so it does seem like they’ve already planned for it.

Although ‘Arrival State of Charge’ was on our wishlist for the Holiday Update, it looks like it may arrive soon after the holidays.
