Tesla detecting distance without ultrasonic sensors
salvagEV's/YouTube
Tesla owner and EV mechanic Occupy Mars shared a video of their salvaged 2018 Tesla Model 3 detecting distances without its ultrasonic sensors (USS).
Occupy Mars shared a 10.5-minute video explaining how they discovered this anomaly. Even though the vehicle was running version 2022.28.2, which was released in September 2022, the vehicle managed to measure distances without the use of USS.
Occupy Mars moved the vehicle out of their garage without the front bumper and confirmed that all ultrasonic sensors were disconnected. However, they noticed that their Model 3 was accurately detecting a vehicle next to it and displaying the appropriate distances on the screen. This appears to confirm that Tesla is testing Tesla Vision to detect nearby objects and display distances, but only on vehicles with USS.
Confirming Camera Detection
Interestingly, Occupy Mars' vehicle only detected the distances while in reverse, although a lot of the car is taken apart, so this could have been due to early software or hardware issues. When pulling up closer to the garage, Occupy Mars noticed the Model 3 was not showing the distance between the car and the garage. Instead, it was detecting objects at the corners of the vehicle. This would make sense given the blindspot in front of the vehicle where cameras can not see.
To confirm that the vehicle was using its cameras to determine distances, Occupy Mars covered the front-facing and B-pillar cameras with tape. Once the vehicle's cameras were covered, the car immediately stopped displaying the arcs and distances from nearby objects.
Occupy Mars went a step further to rule out radar use and physically unplugged the vehicle's radar and with the cameras uncovered, the vehicle continued to detect objects and display distances.

The video below by Occupy Mars shows their vehicle detecting distances without utilizing any ultrasonic sensors or radar.
Running Vision in Shadow Mode
What appears to be happening is that Tesla is actively testing and collecting data from vehicles that are equipped with ultrasonic sensors, and it appears they've been doing so for several months. Previously, the USS were fully responsible for detecting distances for nearby objects, but it appears Tesla is now using an updated version of Tesla Vision in shadow mode. This lets Tesla run code in the background to assess its accuracy before having the vehicle or driver rely on it. Tesla then uses the vision-detected distances and compares those values to the output of the vehicle's ultrasonic sensors, letting them assess the new system's accuracy before releasing it publicly.
The Removal of Ultrasonic Sensors
On October 4th, 2022, Tesla announced that they were removing ultrasonic sensors from their vehicles and beginning the transition into their own proprietary “Tesla Vision.” According to Tesla’s announcement, Model 3 and Model Y vehicles built in October 2022 and beyond no longer included the USS. Later, Tesla removed USS from the Model S and Model X as well.
This came as a bit of a shock to drivers and automotive experts, namely the team from Munro Live. The USS are standard in modern vehicles. They’re used to detect distances in tight spaces to enhance the safety of the vehicle. But Tesla believes they can maintain a similar level of safety and accuracy without the USS, despite some outcry from the Tesla community and experts.
Savings Due to the Removal of Ultrasonic Sensors
Tesla is saving an estimated $114 per vehicle by removing the USS, equating to roughly 100 million dollars per year based on Tesla’s volume, per Munro Live. This effort makes sense as Tesla is revamping its Model 3 to cut costs so prospective buyers can take advantage of the new federal tax credit.
Front Blindspot
Will Teslas have a blind spot directly in front of the vehicle?
Munro Live
As pointed out in the Munro Live video, there is a three-foot blindspot in the front of the vehicle. Tesla’s rumored solution for the three-foot blindspot is to have the vehicle remember what it sees when driving toward an object. But if the vehicle is parked for an extended period and something is placed in front of it, how will the vehicle know where it’s placed or if it has moved?
Tesla could continue processing camera data while parked as they do in Sentry Mode, but this would cause significant battery usage over time.
Tesla may also just leave out the ability to detect objects in front of the vehicle when the vehicle is first started.
Upcoming Update
More recently Tesla owner and hacker GreenTheOnly found code of Tesla testing vision-based USS-type detection in update 2022.40, so it's clear that Tesla plans to address the lack of USS, but it appears the fix is taking longer than expected. Although nothing has been officially communicated by Tesla, we could be close to receiving the long-awaited update that restores USS-type detection.

The latest Tesla Model 3, the fastest yet, is poised to make a significant impact on Tesla's lineup. Speculation suggests the updated Performance Model 3, potentially named "Ludicrous," could be unveiled soon—possibly on April 20. This would, of course, be on 420, aligning with Elon Musk's fondness for the date, which falls 69 days before his birthday—nice.
Revamped Performance and Engineering
"Welcome to the Most Powerful Model 3 Ever," announces the Great Britain Model 3 configurator source code teaser, setting the stage for an electric sedan that surpasses its predecessors in every metric. The heart of the new Model 3 Performance lies in its all-new high-performance drive units, rumored to deliver a combined output of over 500 horsepower. This power upgrade is not just about higher numbers but also about how it translates to the asphalt.

Tesla has reengineered the vehicle with an all-new adaptive suspension system. This system, powered by bespoke in-house software, ensures enhanced body control, maintaining comfort without sacrificing performance. The result is a vehicle that can handle daily commuting as smoothly as it navigates tight corners on a race track.
Advanced Design and Aerodynamics
The Model 3 Performance features redesigned front and rear fascias and a rear diffuser that enhances visual appeal and improves high-speed stability. A carbon fiber spoiler adds to the aerodynamic efficiency while asserting the car’s sporty aesthetics.
One of the standout features of the new model is the Forged Performance wheels. These lightweight, staggered wheels are not just about style; they enhance the vehicle’s turn-in response, improve predictability, and increase traction out of corners, all while optimizing aerodynamics.
Where Comfort Meets Performance
Inside, the Tesla Model 3 Performance introduces a completely revamped interior. The all-new seat design includes enhanced side and cushion bolsters to hold occupants securely in place, which is crucial during high-speed maneuvers. Ventilation is built into the seats to keep the driver and passengers cool and comfortable, reflecting a thoughtful balance between performance and luxury. The cabin's aesthetic is elevated with lightweight carbon fiber décor and a refined weave pattern unique to the Model 3 Performance.

A significant highlight is the Track Mode V3, an innovative feature that allows drivers to tailor the handling balance, stability controls, and regenerative braking to their preferences. This mode integrates a performance-optimized powertrain with adaptive suspension controls, creating a driving experience that is not only responsive but also enjoyable.
The unveiling of the Model 3 Performance is imminent, as indicated by its addition to the configurator source code. There is speculation about a media embargo lifting on the 23rd, possibly coinciding with Tesla’s earnings day, which could provide further details or even see the official launch. My money is on 4/20, which will give a weekend for all influencers who got an early look to ramp up the views and bring that stock (down 40% year to date) some time to rebound before the earnings call.
Tesla's latest V12 user interface will change the look and feel of some of the vehicle’s operations. This new interface, announced on X, is already partially available on the Cybertruck but will now be rolled out to the Model 3 and Model Y, equipped with AMD Ryzen processors according to Tesla. However, the new Model S and Model X will likely receive it as well, although possibly not at the same time. It integrates several new features and aesthetics that set new standards in vehicle interface design.
The new interface will become available in Tesla update 2024.14, which started rolling out to employees yesterday.
New Parked Vehicle Visualization
A standout feature of the v12 UI update, not to be confused with FSD v12, is the centralized vehicle visualization, which dominates the display while parked (video below). This design choice enhances visual appeal and improves functionality by placing critical vehicle performance metrics, and status updates front and center. Similar to the layout in the Cybertruck, this feature provides drivers with a clear and immediate view of their vehicle's status and shows off the gorgeous 3D model.

There’s a new media player that’s larger and easier to use. By increasing the size of the media player, Tesla is now able to fit additional options that were hidden before, such as EQ and audio settings, the search icon and shuffle and repeat options.
The new media player appears while the vehicle is parked, driving or while the visualizations are in full-screen mode.
The media player is available on the Model 3 and Model Y and according to Tesla it’ll be limited to vehicles with the Ryzen-based infotainment center.

Improved Navigation
The navigation system will see several improvements. You’ll now see a little trip progress bar that lets you visually see how far along you are on your route.
If your vehicle has a rear screen, as in the new Model 3, the redesigned Model S or Model X, then trip information such as ETA will also be displayed on the rear screen.
Tesla already has the ability to update your route if a faster route becomes available. You can change some of these settings under Controls > Navigate. However, now the vehicle will show you if a faster route becomes available and gives you a chance to cancel the updated route if needed.
Expanded Autopilot Visualizations
Tesla is now bringing its full-screen visualizations outside of North America. However, there will be some improvements as well. In addition to being able to have the visualizations go full screen, there will now be a small map displayed in the corner as well.
That’s one of the issues with the full-screen FSD visualizations right now. If you make them full-screen, you lose your navigation map completely and only have the next turn available.
This will be the first time full-screen visualizations are available outside North America. It’s not clear whether all the FSD visualizations will be available such as traffic lights, curbs and more will be displayed, but Tesla has slowly been adding additional visualizations for non-FSD users, so there’s a chance that this feature will finally display all FSD visualizations to users outside of North America.
It’s not immediately clear whether this feature will require Enhanced Autopilot (EAP) or FSD.
Update: The full-screen visualizations do not require FSD or EAP, but unfortunately the visualizations displayed are still the same ones as in previous updates, so it won’t display the surrounding environment and curbs.
Full-Screen Browser Support
With this update, Tesla will finally let you manually make the browser full-screen. While this will make Tesla’s Theater apps a little redundant since they just loaded the website of the selected streaming service, you’ll now be able to stream any video service full screen, as long as the service supports Tesla’s browser.
As expected, the full-screen button will only be available while the vehicle is parked.
Checking Compatibility
Owners can verify their vehicle’s compatibility with the new full-screen visualizations while parked and driving by navigating to Controls > Software > Additional Vehicle Info on their Tesla’s touchscreen. This update is tailored for Tesla vehicles equipped with the AMD Ryzen processor.
