FSD Beta 10.4 Improvements with images and video

By Nuno Cristovao

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.

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.

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.

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.

Musk Confirms Robotaxi on Track for June, More Cities Coming, Customer-owned Cars in 2026

Not a Tesla App

Tesla signaled its intention to launch its first Robotaxi network in Austin, Texas, with company-owned and operated vehicles, back in January. This network will be Tesla’s first foray into truly autonomous vehicles - ones that aren’t being directly supervised by a driver. Later in February, Tesla’s executive team confirmed that the plans were on track for the launch of the Austin network both on X and during several interviews that they participated in.

At the end of February, we also found out that Tesla has applied for a Supervised Robotaxi license in California, where the network will also launch, but with safety drivers in place.

This is an ambitious plan, but FSD has really come a long way in the past year. FSD V12 was a massive step forward from V11, and V13 has made the experience smoother and safer than ever before. FSD V14 is expected to be another big step up with auto-regressive transformers and audio input.

Still on Track

Now, Elon has tripled down on the fact that Tesla will be launching their first autonomous robotaxi network in Austin - just two months away at this point. It seems that Tesla is fully set to launch their first fully unsupervised self-driving vehicles that will carry paying passengers in June.

Additional Cities

The best part is that Elon also confirmed that they’re targeting robotaxi networks launching in many cities within the United States by the end of this year. However, remember that this will be a Tesla-run network at first - Tesla owners won’t be able to add their vehicles to the Robotaxi fleet right away.

Adding Customer Vehicles

It will take some time before Tesla meets their strict internal safety requirements before it lets customers add their own vehicles to the network. Tesla’s executive team mentioned that they intend to let owners add their own vehicles to the fleet sometime in 2026. This happens to be the same time frame that Tesla plans to launch the Robotaxi across the United States, Mexico, and Canada — something that could only be done with customer-owned cars.

That final step will be bold—and it may come with complications, especially given that autonomous vehicle approval spans municipal, state or provincial, and even federal levels. There are plenty of regulatory hurdles ahead, but this is undoubtedly shaping up to be one of the most exciting times for Tesla.

Launch Event

With the Robotaxi network launching and Unsupervised FSD just around the corner, there’s a lot to get excited about. Tesla is expected to host a launch event at Gigafactory Texas in Austin to mark the debut of its first Robotaxi network. The company previously hinted that referral code users could receive invites—offering a rare chance to score an early ride in a Robotaxi outside the Hollywood studio lot.

Tesla Mule Model 3 Spotted With Front Bumper Camera

Tesla’s engineering mule vehicles—used to test autonomy for future platforms—have resurfaced after an extended absence. The last time we saw them was back in July, when Tesla was gearing up for its initial We, Robot event. Since then, sightings have been scarce.

These vehicles typically signal that Tesla is testing new camera placements or validating FSD ground-truth data. This time, however, they appear to be outfitted exclusively with the updated camera hardware seen on the Cybercab.

New Sightings

The mules have now been spotted in Boston, Massachusetts, and Concord, New Hampshire—their first known appearances this far east. This suggests Tesla is actively collecting data to evaluate and optimize FSD performance in new regions. Thanks to Reddit user Ready_Medium_6693 for catching the one in Concord.

Elon Musk recently mentioned that Tesla plans to expand Robotaxi networks beyond the initial Texas and California launches. So while these sightings aren’t entirely unexpected, the speed of their arrival is. It suggests Tesla is confident in its ability to train FSD for local traffic rules and driving behaviors to the point it no longer needs a driver.

Bumper Cameras

The vehicle that’s been spotted in Boston is the usual Tesla engineering Model 3… except with one unique twist. It includes a front bumper camera. Shout out to @Dylan02939106 for catching the bumper camera in these photos.

We previously released an opinion piece regarding whether the front bumper camera would be required for Unsupervised FSD. In our eyes, Tesla will require a bumper camera for Unsupervised FSD - if only to improve direct visibility in the bumper area of the vehicle. This is key for low-speed maneuvering in crowded areas like parking lots and garages, as well as for key features like Actually Smart Summon. 

It isn’t surprising that Tesla is continuing to evaluate vehicles with a bumper camera - the Cybertruck, Cybercab, and Refreshed Model Y all have them now - and the rest of the lineup, including the flagship Model S and X, as well as the refreshed Model 3 - were supposed to eventually receive them as well.

With the Model S and Model X set for refreshes this year—and the front bumper camera on this Model 3 looking well-integrated rather than a temporary setup—it seems likely that front bumper cameras will soon become standard across Tesla’s entire lineup.

In fact, Tesla’s newest iteration of the FSD computer has a slot for the Bumper Camera on all AI4/HW4 vehicles, so a future retrofit could even be possible.

These are some pretty exciting times - we may see Robotaxi networks actually deploy in time for Tesla’s lofty goal of “sometime in 2026” for cities throughout North America. Once many American cities begin to accept their deployment, it will be easier to seek homologation in Mexico and Canada, enabling deployment throughout the continent.
