FSD Beta 10.4 Improvements with images and video

Tesla is slowly rolling out FSD Beta 10.4 to existing beta testers. Tesla hopes to expand the beta to users who have a Safety Score of 98 or higher in the coming days. Beta 10.4 builds upon FSD Beta 10.3 in several key areas.

Tesla now displays speed bumps

The first is the crucial and common maneuver known as an unprotected left turn, where your car may have a green light, but needs to wait for oncoming traffic to pass before taking a left turn. Not only does a maneuver like this leave your car vulnerable, but it can also be complicated to complete.

With 10.4, Tesla improved high speed object detection and now allows for faster acceleration across certain roads. These improvements appear to be helping in making more reliable unprotected left turns.

In James Locke's video below, he shows off an impressive unprotected left turn in this newest beta. Not only does the car wait for oncoming traffic to clear, but the car starts slowly accelerating before the vehicle clears it's path, so that the car is up to speed by the time vehicle passes. It's much more natural and human-like behavior.

FSD Beta's visualizations are a big improvement over the visualizations in the public builds, partly due to object permanence.

The software is able to tell the difference between an object moving or disappearing versus it being hidden by another object. If there was a person in front of your car, but then a vehicle slowly drove by, between your car and that person, we'd likely conclude that the person is still there, just hidden behind the car.

That's what Tesla is doing now, not only with visualizations, but what the car sees as its surroundings. Once the car sees an object, it records it's time and position in the world in a semi-permanent state. Even when the car can't see the object any longer, it still knows it's there.

Sure, this could lead to some errors, but it often does in humans as well. In the example above, where the person was obscured by the car, it's possible the person got into another car or left the scene without us seeing because the car was blocking our view.

In this update, we're seeing more complete visualizations thanks to Tesla drastically improving the detection of VRUs (vulnerable road users) such as pedestrians, bicyclists and motorcycles by using a next generation auto labeler.

You can read the complete technical release notes for the FSD Beta 10.4.

New Visualizations

Visualizations also received a small update. The car was already detecting and slowing down for speed bumps, but speed bumps are now shown in the visualizations as well.

Crosswalks also received a minor visualization update. They used to be depicted as two white parallel lines, but they now appear as a filled in dark area on the screen. They're a little more obvious and there are less jagged lines, but they also don't exactly look like crosswalks either. If Tesla added the thick stripes crosswalks usually have, that could prove useful.

FSD Beta now displays clearer crosswalks

There are other smaller improvements in this beta such as improved emergency vehicle detection, improved VRU relevance by using the vehicle's intended path and more.

Improved Warnings

Tesla has greatly improved driver monitoring by not relying solely on steering wheel tension and instead using the interior camera. Tesla apparently started included the interior camera in Model 3s apparently for a robotaxi future, but it appears to have paid off for FSD instead. Relying on steering wheel tension was unreliable and an annoyance for drivers.

With the cabin camera Tesla can closely monitor where the driver is looking and constantly checking whether they're paying attention. An inattentive driver will receive an instant warning to pay attention if they're looking down, staring at their phone or looking to the side if Autopilot is activated.

FSD Beta warning

Early last month Tesla starting enforcing stricter rules when using FSD, where they will kick out beta testers if they're caught not paying attention several times.

In this beta, Tesla appears to have expanded these warnings to being on-screen as well, instead of relying on an email message. These warnings will be crucial to Tesla keeping the FSD Beta program and remaining accident free.

What's Not Included Yet

We know two big features are coming to FSD soon, but they're not yet included in this 10.4 update. The first is using a single stack for city and highway driving. Highway Autopilot is still completely separate and the same as the public build.

We're also anticipating the feature that will give the vehicle the ability to go into reverse. If the vehicle creeps forward for better visibility and decides it's unsafe to proceed, it'll back up to move out of the way of others.

Elon first anticipated this feature to come in FSD Beta 10.1, but we haven't seen it in FSD builds yet.

It's possible we may see both of these features added in the next major FSD release v11, which may come as the next FSD Beta. FSD Beta 10.4 also includes Sentry Mode Live Access for those with a Model 3, Model Y or the new Model S and X.

Tesla’s New Signal Viewer Panel in Service Mode+ Allows You to View Real-Time Data

@scotsrule08 on X

Tesla’s latest software update, version 2025.2, brings new features to Service Mode, continuing the trend of improving in-vehicle diagnostics.

Currently, this feature is only available for vehicles with AMD Ryzen infotainment systems and requires Service Mode+, which is a subscription service aimed at technicians. Intel-powered vehicles aren’t supported yet, but we expect this feature to roll out to them as well unless hardware limitations prevent it.

Thanks to Spencer for providing an image of the panel in action.

Signal Viewer Panel

While update 2025.2.6 adds four service mode improvements, including updates to brake burnishing, charge port calibration, and noise recording panel improvements. In this article, we’ll focus on the new signal viewer panel.

This new panel offers a live data feed from selectable vehicle sensors. You select the signals you’re interested in and it’ll plot the signal on a graph. In addition to allowing you to view real-time signal data, it also allows you to record them.

The signals are searchable and can be easily added or removed from the panel. You can track up to 10 sensors, and the UI allows three of them to be viewable at once.

However, this is Service Mode and it’s more than just pretty looks. You can really dig down into these charts. You can pan them left and right through time, and tapping a specific point shows the exact value of that signal. The panel also supports pinch-to-zoom, enabling you to adjust the time scale across all panels simultaneously.

This feature is exclusive to Service Mode+, which requires a subscription to Tesla’s ToolBox3 software and a connection to a computer. It’s designed to help technicians diagnose issues related to signal quality, noise in the vehicle’s electrical systems, and signal variance in components during driving.

We’re excited to see Tesla’s continued focus on repairability, especially with additions like the Cybertruck’s Interactive Wiring Diagram and the launch of the Tesla Online Parts Catalog, which lets customers purchase parts directly.

Plus, with the reduced cost of ToolBox 3 subscriptions, even DIY enthusiasts now have access to tools that make Tesla repairs more accessible.

Tesla Introduces New Model Y Variants in Europe; Ends Launch Series

Not a Tesla App

Tesla has updated its Model Y lineup in Europe, introducing new standard configurations while discontinuing the limited-edition Launch Series. With the new variants now available, European customers will have more choices and cheaper options to pick from.

The Launch Series and some of its exclusive features will no longer be offered—except in the UK, where it remains available alongside the new lineup.

New Models Introduced

Tesla’s new Model Y lineup in Europe includes three main variants. The prices vary slightly from country to country.

• Rear-Wheel Drive (RWD): Priced at €44,990, this model is the most affordable new Model Y, but it also has the shortest range and is missing a few features available on other trim levels.

• Long Range Rear-Wheel Drive (LR RWD): Available for €49,990, this version is essentially the same as the RWD model, but with a larger battery. It has seen a €1,000 price increase compared to the outgoing Long Range RWD model.

• Long Range All-Wheel Drive (LR AWD): At €52,990, this model has seen a price drop of €2,000, making it a better deal than the previous LR AWD Model Y. This is also the only new Model Y to come with most of the same features as the Launch Series, including additional speakers, a subwoofer, premium materials inside the cabin and improved acceleration. Acceleration boost should also become available for this model, letting it match the performance of the Launch Series.

All Model Y variants come with all the improvements that we’ve discussed about the new Model Y, including the new front and rear light bars, improved aerodynamics, ventilated seats, improved heat and sound isolation, and the 8-inch rear touchscreen. Some exclusive options, like the Midnight Cherry Red paint, appear to no longer be available. However, Tesla has already said that they’ll be introducing new paint options for the Model Y in North America.

Compare Model Y Variants

Here’s how the various Model Y variants compare to each other:

Launch Series Ends

Not a Tesla App

The Launch Series, which debuted just weeks ago in Europe, has now been phased out. This limited-edition model was priced at €60,990 and included a suite of premium features comparable to a bundle deal you may find with other products. It came equipped with Full Self-Driving (FSD), Acceleration Boost, and exclusive badging on the rear liftgate, door sill plates, and puddle lights.

While the Launch Series is no longer available for new orders in most European countries, customers can still get a similar vehicle by opting for the Long Range AWD model and manually adding premium features like FSD. Acceleration Boost, which was standard in the Launch Series, is expected to become available for purchase once these vehicles are delivered or soon afterward. However, some exclusive elements, such as badging and trim details, will remain unique to the discontinued edition.

For now, the UK remains an exception, still offering the Launch Series alongside the newly introduced models.

Performance Model Still to Come

With Tesla now introducing the expected variants of the refreshed Model Y, one notable absence is the Performance model. While the Launch Series was fast due to the Acceleration Boost addon, there’s no doubt the Performance version will be in a league of its own.

What we saw Tesla do with the 2024+ Model 3 Performance variant was more than just using binned motors. The vehicle featured unique bumpers, a spoiler, an improved suspension, sport seats, Track Mode V3 and other features that made the vehicle stand out compared to the Model 3 AWD.

The Performance version of the new Model Y is expected to become available later this year, however, expect it to carry a $5-$8k premium over the AWD model.

Other Regions to Follow

As Europe phases out the Launch Series, other regions are expected to see similar changes. With the other models now revealed, owners in other regions have a better idea of whether they should buy the Launch Series or wait for the additional models to arrive.

Tesla naturally adjusts its offerings based on market demand, and if sales of the Launch Series remain strong in other parts of the world, Tesla will likely wait it out a little longer before offering the other models.
