Tesla's early FSD Betas included driving visualizations that used simple wireframe boxes to represent vehicles and lane markings were made up of individual dots.
Tesla adds scalable vehicle models to the latest FSD Beta
The visualizations were a great look into some of the information that is provided to Autopilot, but even then only a fraction of the information Autopilot uses was actually displayed onscreen.
In reality, Autopilot is creating a 3D representation of every object it tracks. Each object detected then has various attributes. For example, a detected vehicle will have attributes for how fast it's going, how far away it is, the type of vehicle, its predicted path, and more.
Tesla's visualizations in early FSD Betas
The car visualizations are an important part of FSD because they help us better understand what the car is capable of seeing and reacting to. However, the information and visualization Autopilot needs is drastically different than what humans need.
In order for Tesla to achieve FSD, they essentially need to be able to build a highly accurate video game that represents the real world, in real-time.
The car wants access to as much information about each object as possible. Meanwhile, humans want a visualization that closely resembles the real world.
With the introduction of FSD Betas 9.x, Tesla released a more human consumable visualization. One that included proper 3D models of general vehicle types, road pylons, and solid lane markers.
The road edges and lane markings are more distinguished lines, 3D models have working brake lights, and other objects such as speed bumps, bike lanes, and crosswalks are depicted using visualizations that match the real world.
In order for Tesla to achieve FSD, they essentially need to be able to build a highly accurate video game that represents the real world, in real-time.
However, something that has been missing is visualizations is dynamic vehicle sizing. The 3D vehicle models that Tesla has been using have a static size. When the vehicle sees a bus, it calculates its length, width, and height in addition to a bunch of other metrics. However, the 3D model that is shown onscreen is a predefined size, meaning that it does not actually match what the vehicle saw.
This is why you may have seen a tractor-trailer shift forward and backward or you may have seen two vehicles on top of each other. One is signifying the start of the vehicle and since the vehicle is so much longer than the model, it's adding another vehicle to the end to signify the end of the vehicle.
Scalable Vehicle Models
However, in the latest 10.10.2 FSD update, we are now seeing Tesla scale individual vehicle models so that they represent the calculated size of surrounding vehicles. Contextually this could be helpful in better understanding our car’s situation in the world.
In 10.10.2, the car shrinks or stretches the 3D vehicle models in each dimension so that the 3D model matches the calculated dimensions for each vehicle. This is especially apparent in longer vehicles such as buses, trucks, and tractor-trailers, where the vehicle lengths are more likely to vary, but you can also see it scale other vehicle models such as very small cars.
In this example below, you'll see that Tesla is now able to accurately represent buses of different sizes. Tesla only has a model for a full length bus, but in this case, Tesla detected that the length of one of the buses is considerably shorter than the vehicle model so it chose to reduce the length of the bus to the length Autopilot had calculated. In the image below you can see how the same bus model is shown in two different sizes.
Tesla can now accurate render vehicles of different sizes
It's important to realize the difference between the visualizations and what Autopilot uses. The visualizations are there merely to help us better understand what Autopilot can see. The FSD computer itself has always been taking note of the size of surrounding objects and various other data points. Trajectory, approach velocity, proximity, and so forth have also been a part of this, but this update helps Tesla achieve visualizations that provide a more accurate representation of reality.
It's not only buses and trucks that are scaled up or down. Tesla resized a bobcat down to a vehicle that is about half the length of its normal sedan model.
Tesla can now accurate render vehicles of different sizes
Models are adjusted in all three dimensions. We witnessed some truck models that were stretched to become taller while also having their length reduced. It's not perfect because you're scaling all components of the truck at the same rate, but it produces a much more accurate representation of the vehicle and the amount of space it takes up.
Vehicles are resized in three dimensions to better match the vehicle's length, width and height
Tesla has come a long way in a short period with how many objects they're able to detect, but obviously, when you compare the environment the car sees today, there is still a lot missing.
In the short term, we'd like to see more objects visualized. Objects that are commonly encountered while driving, such as trailers and gates.
We'd also like to see other common objects added, such as additional traffic light configurations, crosswalks, mailboxes, and maybe even a generic object that lets us know the vehicle sees something it needs to maneuver around, but it may not know exactly what it is.
In the future, I think we'll see Tesla display a rich, fuller 3D environment that will display static and moving objects that are important for the vehicle to avoid, objects such as barriers, buildings, trees, sidewalks, and more. Today Tesla is one step closer to achieving this goal.
Tesla has begun installing a new set of anti-theft measures on some Supercharger cables. This is a two-part process, and includes an exterior-wrap called DyeDefender, as well as engravings on the actual copper of the Supercharger cables themselves.
Superchargers, just like other high-speed electric vehicle charging stations, have been consistently subject to both vandalism and theft. While vandalism is something that can be reduced by increasing policing and security in the area, theft is a different beast to tackle.
Thieves are usually after the copper inside the charging cable - which is densely packed and valuable when taken to a scrap yard. So how is Tesla tackling this?
DyeDefender
First up is a field trial of a product called DyeDefender. You can find this product online to secure ICE catalytic convertors, but the overall premise is fairly simple. A pressurized staining dye is housed inside a stainless steel hose, which is laid overtop or around the object you need to protect - in this case, the Supercharger cable.
The stainless steel cable itself is called CatStrap - and is extremely difficult to cut through. If you do manage to cut through, the dye squirts out, coloring you blue quickly. The dye itself is harmless, but helps to identify potential thieves. Tesla’s Head of Charging - Max de Zegher, confirmed that this is only a trial rollout - instead, Tesla is considering another alternative.
Tesla has begun installing new anti-theft measures on some Supercharger cables, consisting of an exterior wrap called DyeDefender and engravings on the copper wiring inside the cables.
Like other high-speed EV charging stations, Superchargers have been frequent targets of vandalism and theft. While vandalism can often be mitigated through increased security, theft presents a bigger challenge. Thieves primarily target the copper inside the charging cables, which is densely packed and valuable as scrap metal.
DyeDefender
To address this, Tesla is trialing DyeDefender, a theft deterrent system commonly used to protect catalytic converters. It consists of a pressurized staining dye housed within a stainless steel hose called CatStrap, which wraps around the Supercharger cable. The CatStrap is highly resistant to cutting, but if breached, it releases a bright blue dye. While harmless, the dye is difficult to remove, making it easier to identify suspects.
In addition to DyeDefender, Tesla is also engraving the actual copper wiring inside the cables, making stolen material harder to sell since scrapyards often reject marked metals.
Engraved Cables
This alternative is more scalable, more cost effective, and doesn’t impact service operations or the customer experience - and its simply engraving the copper inside the cables. Superchargers cables will state “Property of Tesla” on them - engraved right into the cable from the factory in Buffalo, New York.
Engraved -
Not a Tesla App
Recycling companies and scrap yards will see that the cables belong to Tesla - and won’t accept them. Instead, they’ll reach out to Tesla to inform them that they have received stolen goods. While that may not have an impact immediately - as thieves learn that the copper they steal from Superchargers is worthless and could risk them getting in trouble, they’ll be less likely to go ahead and try.
It is definitely interesting to see Tesla try out some rather unique options to keep Supercharger sites safe and functional. Tesla will likely focus the deployment of DyeDefender in areas that experience continual theft - but again, this is only a trial. The impact of cable engraving will likely take some time, but it’ll pay off in the long run.
Until then, make sure to keep reporting any downed Supercharger sites. You can do that in the Tesla App through Location > Charging >Select Site > Report an Issue. If you have any other neat ideas on how Tesla can stop vandalism and theft, let us know in the comments or in the forums!

This solution is more scalable, cost-effective, and doesn’t disrupt service operations or the customer experience—it simply involves engraving the copper inside the cables. Supercharger cables will be permanently marked with “Property of Tesla Motors,” engraved directly at the factory in Buffalo, New York.
Recycling companies and scrap yards will immediately recognize that the cables belong to Tesla and refuse to accept them. Instead, they may notify Tesla that they’ve received stolen goods. While this may not have an immediate impact, over time, as thieves realize that stolen Supercharger copper is unsellable and could get them caught, they’ll be less inclined to target them.
It’s interesting to see Tesla experiment with unique ways to protect Supercharger sites. While the company will likely focus on DyeDefender deployments in high-theft areas, this remains a trial phase. The full impact of cable engraving may take time to materialize, but it should prove effective in the long run.
In the meantime, continue reporting any downed Supercharger sites through the Tesla app by navigating to Location > Charging > Select Site > Report an Issue.

Tesla has released software update 2025.2.6, and while minor updates typically focus on bug fixes, this one introduces a major new feature. With this update, Tesla has activated the in-cabin radar, a sensor that has been included in some vehicles for more than three years but remained unused until now.
Why Not Vision?
Unlike vision-based systems, radar can precisely measure object dimensions and even detect movement behind obstacles by bouncing radio waves off surrounding surfaces. This allows for more accurate and reliable measurements of objects that vision may not even be able to see, such as behind the front seats.
What Tesla Announced
Tesla recently highlighted the 4D radar in the new Model Y, explaining how it will improve passenger safety. Tesla executives stated that the radar would be used to properly classify passengers and improve the way airbags deploy.
Tesla went on to say that in a future update, Tesla will use the in-cabin radar to detect any potential passengers left in the vehicles. Since radar can even pick up on heartbeat and breathing patterns, it can provide a much more accurate method of detecting children left in a vehicle. Tesla talked about how the vehicle will send owners a notification via the Tesla app and enable the HVAC system if it detects a passenger in the vehicle. It’ll even call emergency services if needed.
New Feature in Update 2025.2.6
Tesla has officially named this feature in update 2025.2.6, “First-Row Cabin Sensing Update,” which appears to align with the first portion of what Tesla discussed in the new Model Y video.
In the release notes, Tesla describes the update as:
“The first-row cabin sensing system has been updated to use cabin radar, which is now standard in all new 2025 Model Ys. Your Model Y was built pre-equipped with the necessary hardware, allowing Tesla to also bring this technology to your vehicle.”
For now, it appears that Tesla is using the radar to detect and classify passengers in the front seats. This could eventually replace traditional seat sensors, reducing the number of hardware components and lowering production costs.
Tesla plans to expand the feature later this year, bringing rear-seat passenger detection in Q3 2025. While Tesla talked about the feature for the new Model Y, we expect it to be available for all vehicles with the in-cabin radar.
Supported Models
Although Tesla is vague in their release notes, this feature is being added to all Model Ys that include a cabin radar. Tesla started including the cabin radar in 2022, but its availability may vary by region and model. The Model 3 didn’t receive the cabin radar until it was redesigned in 2024, while all Cybertrucks already include it.
The owner’s manual for the redesigned Model S and Model X doesn’t specifically mention the interior radar, although Greentheonly believes the vehicles also include one, so we’ll have to wait to determine whether those vehicles also receive this new feature.
At this time, the feature appears to be only going out to Model Y vehicles, but we expect it to become available on other supported models soon.
We love to see these kinds of updates. Tesla is increasing the safety of existing and new vehicles through a software update while also making them more affordable to own.
