Tesla recently hit the news for purchasing approximately $2M in LiDAR sensors from Luminar, one of Tesla’s long-term suppliers. You’ve probably seen photos of Tesla’s Semi and various Tesla models, including the Model 3 and Model Y sporting LIDAR equipment on the roof. These cars drive around with manufacturer plates scanning streets and highways.
However, many people confuse Tesla’s purpose in purchasing LiDAR equipment with using it for FSD versus testing. So, let’s look at what LiDAR is, and why Tesla uses it on its Fleet Validation Vehicles.
What is LiDAR?
LiDAR stands for Light Detecting and Ranging – essentially using lasers to measure distances. A laser pulse is sent out, and the time it takes to return is measured – providing extremely accurate distance measurements.
Some companies working on self-driving vehicles, including Waymo and BYD, use LiDAR as part of their self-driving suites, but Tesla is one of the few stand-outs that does not. Even Rimac’s “Verne” Robotaxi – which uses self-driving technology from Mobileye, also uses LiDAR.
While LiDAR can produce extremely accurate and high-quality 3D environments, it comes with its downsides as well. Not only is LiDAR costly and requires large gear strapped to a vehicle, but it also can not be used in bad weather and can have interference issues if there are other strong light sources present.
Why Does Tesla Use LiDAR?

At Autonomy Day in 2019, Elon Musk mentioned that LiDAR isn’t the solution for self-driving cars – it's just a crutch. Thus, Tesla hasn’t used LiDAR for any production self-driving software.
Instead, Tesla uses it exactly how it's described – they use it to gather ground-truth data. This data is then used to feed Tesla’s Full Self Driving system – which helps validate its vision-only system's accuracy. LiDAR provides very accurate measurements to help ensure that FSD’s perception of space is accurate – and is only used by Tesla to ensure that its AI technology which is the brains of FSD is capable of accurately interpreting depth from just visual data.
Rendering of what Tesla's license plate feature could look like
Not a Tesla App
Tesla update 2024.38 has started rolling out to several regions and vehicles. Thanks to Tesla hacker Greentheonly, we have a behind-the-scenes look at some new features coming to Teslas.
License Plate Display
According to Greentheonly, it looks like Tesla may soon let you display your actual license plate in the vehicle’s visualization on the screen. In our article, The Most Request Tesla Features, several readers suggested displaying the vehicle’s license plate in the visualization instead of a blank, white plate.
It looks like Tesla will be doing just that, at least in China. Green found references that appear to conclude that you’ll be able to display your vehicle’s plate on screen. This will likely be user input, so you could have it say anything you’d like, and it doesn’t have to be your actual license plate.
For many owners, who may find it difficult to remember their license plate, this could serve a practical purpose in addition to adding to the visualization's realism.
While Green was only able to say it’ll be available in China, we expect this is due to China’s software development team working on it and that it’ll eventually be released worldwide.
While code for this feature was found in update 2024.38, we may not be turned on in China yet. We suspect this feature may be a strong candidate for Tesla’s upcoming holiday update.
FSD Hardware Version Display
As part of the 2024.38 update, Tesla has now made it easy to determine whether your vehicle includes Hardware 3 or Hardware 4. You can now simply navigate to Controls > Software and tap Additional Vehicle Information. In addition to other hardware information about your vehicle, your Autopilot hardware version will now be listed as well.
You can see whether your vehicle has HW2.5, HW3, or AI4. This in-car display is useful, but if you don’t have access to the vehicle, you can always use our guide on how to determine the hardware version of a Tesla.
New Battery Health Test & Service Mode Improvements
Green found some additional things as well. There’s a new and improved Battery Health Test. The new test will show you how your car scores compared to similar vehicles in the Tesla fleet.
In addition, maintenance records can now be permanently stored “in the car.” It doesn’t appear that this feature is activated yet, but it’s likely in active development with some parts leaking out in the 2024.38 update.
Tesla has included various Service Mode improvements and new visualizations in this update.
Mr Li on X came across some covered-up Project Juniper vehicles recently and he managed to get various shots of the vehicle.
Juniper Images
This front image reveals what looks like two rows of lights, possibly confirming the front light bar for the Model Y refresh — similar to the one on the Cybercab.
The rear side has a lot of lights on it!

The rear side shows a ton of brake lights, but it’s not clear why. While it looks like the Model Y refresh will also feature a rear light bar similar to the Cybertruck, there isn’t strong evidence of that in this photo.

There's an obvious set of lights at the bottom, so it looks like the Model Y refresh will be similar to the new Model 3 where the bottom lights can operate as brake lights when the one-piece tail lights and trunk are up.

In the last photo, we see that the overall form factor of the refreshed Model Y will remain unchanged, and Tesla is focusing the changes on the front and rear ends of the vehicle, much like the Model 3 refresh. However, in this one shot, we can also see what appears to be red light leaking out of the rear camera cover opening, possibly due to the rear light bar.
The Model Y is not only Tesla’s best-selling vehicle but also the world’s best-selling car in 2023. This year, it’s expected to be the best-selling vehicle in the United States and again in the world, so this refresh will be huge for Tesla.
@DominicBRNKMN made another fantastic set of concepts based on these new images. Given he had the most accurate Model 3 Highland concept before the official launch, we’re pretty sure his latest work be close here as well.

We’re super excited to see the eventual reveal of Project Juniper, which is expected in the first half of 2025. However, expect to see a few more leaks before production kicks off at Giga Shanghai.
