Tesla registered a new high resolution radar unit with the U.S. Federal Communications Commission (FCC). Tesla's intended use for these radar units is unknown, but it appears they are intended for imaging, similar to how LiDAR uses lasers to map surroundings.
While Tesla's FSD software has used radar in the past, Elon Musk has a rather unfavorable stance on LiDAR. For the purposes of autonomous driving, Musk sees LiDARs as a "fool's errand." Yet, people have been spotting Tesla prototypes with LiDAR sensors since last year.
Tesla files a patent for a high-res radar sensor
The latest instance of Tesla using LiDAR comes from Twitter user @ManuelRToronto who spotted a LiDAR-mounted Tesla in downtown Toronto, only a few weeks after the release of FSD Beta in Canada.
He took a video of the LiDAR-mounted Model Y with manufacturer license plates from California.
There has been no official announcement from Tesla about these LiDAR-mounted vehicles, but it is safe to assume that Tesla will not use LiDAR on any production vehicles.
Tesla is likely using LiDAR to help train their machine learning algorithms, using it as the ground truth when checking for accuracy. Unlike cameras, LiDAR captures extremely accurate 3D depth measurements.
LiDAR could be used to train these algorithms to accurately interpret depth by relying on precise, non-interpretive LiDAR sensors.
Cameras are limited to 2D data combined with computer vision algorithms to interpret 3D depth. The downside to this approach is that it requires a computational process versus having precise 3D depth measurement from a LiDAR sensor.
However, LiDAR sensors are expensive; the benefit of relying solely on cameras is that it makes Teslas much more affordable.
LiDAR can't be the only sensor used in a vehicle since it can only build a wireframe 3D environment. Without cameras it wouldn't be able to read traffic signs, traffic lights or anything that doesn't have depth.
Vehicles with LiDAR also rely on camera data and fuse the two outputs of the two sensors together to build a virtual representation of the real world.
Musk believes that self-driving cars should navigate the world in the same manner as human drivers. Since humans use their eyes and brain to navigate three-dimensional space, cars with cameras and enough computational power should be able to achieve the same thing.
"Humans drive with eyes and biological neural nets, so it makes sense that cameras and silicon neural nets are the only way to achieve a generalized solution to self-driving, " says Elon Musk.
While other self-driving initiatives like Google's Waymo have taken a LiDAR approach, Tesla is outpacing the competition using vision-only, machine learning and the network effect of over 100,000 vehicles in the FSD Beta program.
Tesla's vision-only approach has become smart enough that adding radar data gives the system more information than it needs and disorients the FSD software.
LiDAR and radar may be helpful in training the FSD software, but Tesla wants to avoid using multiple sensors with potentially conflicting perceptions that would overwhelm the system.
With Tesla's recent patent of a high resolution radar, and the recent reported use of LiDAR, it is possible that Tesla's Robotaxi will employ radar and/or LiDAR in order to reach full automation.
Levels of driving automation
Synopsys
Tesla's FSD software could eventually be segmented into consumer and commercial self-driving vehicles with consumer vehicles reaching conditional autonomy (L2/L3) using vision-only and commercial vehicles reaching full autonomy (L4/L5) with the help of radar or potentially even LiDAR sensors.
Commercial robotaxis could even be multi-sensor (cameras, radar, LiDAR), costing much more, while consumer self-driving vehicles would be vision only and more affordable.
With most vehicles moving on to Tesla’s 2025.14 Spring Update, we’re now taking a look at all the undocumented features that were discovered during Tesla’s 2025.8 update.
While these features tend to be smaller in nature, some of them are just as valuable as the features outlined in Tesla’s release notes in the vehicle.
This update includes changes such as improvements to maps, trip meters, and Rainbow Road. Let’s take a look at all the undocumented features in Tesla’s 2025.8 software update.
New Map Icons
Not a Tesla App
Icons on the map are being redesigned to be rounder and easier to see. They now feature a white border to make them pop out against a colorful background, which is especially better when using satellite views.
This feature started rolling out slowly but should now be available to everyone.
Trips & Odometer
Not a Tesla App
The Trips display has been improved to show more precise information, and a new metric has been added.
More Precision: The trip meters will now show values with a tenths place when they’re under a certain value. That means that the Current Drive and Since Last Charge trip meters will now show a fractional kWh and a mile. This is especially useful for Current Drive.
The Current Drive meter is automatically reset when your vehicle comes out of park so that it can track your current drive, while the Since Last Charge meter automatically resets after a charging session completes.
More Data: In addition to added precision, the Current Drive now features a new data point. kWh is now shown for the current drive, just like the other trip meters. Previously, the Current Drive showed minutes instead of kWh -- it now features both.
These changes affect the Trips widget in the Model 3, Model Y and Cybertruck. While the added precision is also added to all vehicles under Controls > Trips, the new kWh metric for the Current Drive is only displayed in the small widget.
Additional Tool Tips
Not a Tesla App
Tesla has added some additional tips to the screen that show up in certain cases. For example, if you’re playing audio over Bluetooth, Tesla will suggest that you use their built-in music apps instead of streaming through your phone.
Destination Charging
Not a Tesla App
Destination charging icons are now visible on the map when you have Points of Interest enabled. You can enable Points of Interest by tapping on the map and choosing the Points of Interest icon on the right side near the satellite imagery icon.
Some destination chargers may charge a fee, while others may be open to the public or exclusive to paying customers.
Navigation Improvements
Not a Tesla App
If you're using Tesla's navigation system with voice guidance enabled, the spoken directions will now stop immediately when you end the trip. Previously, the spoken directions would continue being played until the phrase was completed.
Improved Rainbow Road
Not a Tesla App
The rainbow road feature has been greatly improved in this update with FSD. Rainbow road, which can be enabled in the Toybox app, now changes the vehicle's path when on Autopilot from a blue path to a rainbow one.
Previously, Tesla had to overlay the blue path on top of the rainbow colors because rainbow road didn’t support all the features of the path, such as showing chevrons when slowing down rapidly.
With this update, the rainbow path now incorporates all the same features as the blue path when FSD is active.
In addition, if you start Rainbow Road by tapping the right stalk four times, audio will play. Unfortunately, the sound couldn’t be stopped until it was completed before, but with this update, you can now stop the audio by reducing the volume with the left scroll wheel.
Additional Transparency Effects
Not a Tesla App
On Intel vehicles, several modules didn't include a transparency effect. This was primarily due to Intel cars not using the blur effect since it could slow down the infotainment unit.
With this update, Tesla has enabled the transparency effect across a set of modules. Notably, this fixes the issue when using full-screen visualizations where the music player had transparency, but the navigation module on the right did not.
Transparency has also been added to other modules that are displayed over the map, such as the list of Superchargers, destinations, search results, and the ETA / End Trip module displayed at the bottom.
Note: Due to the lack of the blur effect on Intel due to performance reasons, these changes could make some text more difficult to read.
No Phone Key Graphic
Not a Tesla App
The graphic that's displayed in the vehicle when it doesn't detect a phone key has been updated. Tapping on the blue text at the bottom displays the old animation showing you where to tap a key card.
Bluetooth Player
Not a Tesla App
The Bluetooth app typically only displays the connected devices and a button to connect a new device. There was a lot of white space, since there wasn’t much other information to display.
With this update, Tesla is making it easier to jump to another source by displaying available music streaming services underneath the connected Bluetooth device.
Tapping a music service will jump to the selected service.

Next Update
Tesla’s next update is the 2025.14 Spring Update, which has now rolled out to more than half of the Tesla fleet. If you’re still waiting for it, rest assured that you should be updated soon. If you’ve already updated, be sure to check out the undocumented features already found in the 2025.14 update.
Tesla has issued a strong denial in response to a Wall Street Journal report (Paywall) which claimed that Tesla’s Board of Directors had initiated a search for a new CEO.
In a statement posted directly on Tesla’s X account, Board Chair Robyn Denholm denied the report unequivocally. As per the statement, Tesla’s board did not reach out to recruiting firms in search of a new CEO.
Earlier today, there was a media report erroneously claiming that the Tesla Board had contacted recruitment firms to initiate a CEO search at the company.
This is absolutely false (and this was communicated to the media before the report was published).
The statement reaffirmed the board’s position on Tesla’s current leadership and that the board is highly confident in Elon’s ability to continue executing Tesla’s plans and future growth.
This confidence behind Elon follows his recent statements made during the Q1 2025 Earnings Call that he would be stepping back from the Department of Government Efficiency (DOGE) in the coming days and significantly reducing time spent there. Instead, he would be returning to focus on Tesla’s operations and the upcoming deployment of Robotaxi.
Shortly after the denial was posted, Elon Musk also commented on the report, specifically tagging the Wall Street Journal and criticizing their handling of the report.
It is an EXTREMELY BAD BREACH OF ETHICS that the @WSJ would publish a DELIBERATELY FALSE ARTICLE and fail to include an unequivocal denial beforehand by the Tesla board of directors! https://t.co/9xdypLGg3c
We’re glad to see Tesla and Elon set the matter straight, but there could have been a better way to spread this message and maybe even prevent the report from WSJ from going out.
We recently published an opinion piece on why Tesla needs its PR team back, and this specific incident is a good example. Relying solely on platforms like X for critical corporate communications - and in this case, late at night (1 AM EST), with limited reach outside the existing follower base seems like an ineffective way of communicating important company information.
We’d love to see Tesla really put some thought into managing its image, as it seems that several recent reports from major financial news organizations have apparently been wrong.
Either way, the board’s stance is clear - there is no active search underway, and Elon has the full backing and support of the board to lead Tesla toward the future.
