Tesla released its high fidelity park assist feature during its 2023 holiday update
YouTube/AI DRIVR
A new video on YouTube (posted below) provides an in-depth look at Tesla's High Fidelity Park Assist. Viewers can get a good look at the system’s ability to accurately visualize and interact with the car's surroundings for improved parking assistance but also understand its weaknesses.
Urban traffic and limited parking spaces have made parking challenging, often leading to congestion and increased risk of accidents. Tesla's High Fidelity Park Assist is not just about making parking easier; it's about transforming it. Tesla is just cameras to create a 3D visualization of the car’s surroundings, enabling precision parking like never before.
Breakthrough Features of Tesla's Park Assist
AI DRIVR notes the visual accuracy and the clear view of the surroundings. It vividly shows barriers, crosswalks, parking spots and more. It goes beyond objects that FSD could identify, and even for objects that can’t be identified, they are still displayed on screen in 3D. AI DRIVR also does a great job of pointing out some weaknesses in the current system and determining its accuracy.
Upcoming Improvements
As we know, Tesla is constantly improving, but the first version of this system shows where the following upgrades may further advance the technology. Future versions are expected to offer even more precision and more accurate visual representations. The video presenter suggests the system might even cover larger areas and shift away from gray tones by overlaying images on the 3D objects.
The feature is currently limited to vehicles without ultrasonic sensors (USS), but Tesla’s director of Autopilot already said that the feature will also come to vehicles with USS. However, it’s not clear whether the feature will be limited to vehicles equipped with Ryzen-powered infotainment systems (MCU 3).
Tesla’s improved Park Assist is also currently limited to lower speeds (below about 3 mph), however, this could be expanded as well. One day FSD visualizations could be completely based on this technology instead of relying on pre-made 3D models.
Accuracy and Limitations
The technology accurately renders objects like cones and curbs, but the presenter notes that the system's accuracy diminishes with proximity to objects. Another area for improvement will be hardware and, obviously, the addition of a front bumper camera. Cars with front bumper cameras will benefit far more from this technology. However, there are no future retrofits, and only the newest production models are equipped with front cameras, such as the Cybertruck. The video notes that the system needs to improve in showing objects directly in front of the car.
Interestingly, the video shows the system performs much better backing into places. It’s likely due to that wide-angle camera. If you or your teenagers have gone through any driver’s training lately, you probably know that backing into spaces is recommended. It allows for a much safer departure from the space, and the new High Fidelity System is set up very well for that.
The High Fidelity Park Assist system represents a significant improvement in Tesla’s Park Assist. These vehicles were previously limited to Park Assist with questionable accuracy. Its ability to now accurately visualize surroundings in real-time offers a safer and more efficient parking experience. The system's ongoing development promises continual improvements, potentially leading to more precise and reliable parking assistance than currently available with ultrasonic sensors. This technology sets a new standard in the evolution of Tesla’s Park Assist.

Tesla’s refreshed Model Y is currently being manufactured as Tesla prepares for its first deliveries next month. While we’ve already seen quite a few cool new features, there’s more that has yet to be revealed. A recent video interview with Tesla’s engineering team hosted by Tesla Owners Silicon Valley reveals that the vehicle includes a new 4D cabin radar.
4D Radar
While Tesla has included an in-cabin radar since 2022, this appears to be a new, more capable radar. The current cabin radar is used to verify seat occupancy, but Tesla plans to add more functionality to this new system.
This updated radar will be used to provide a lot more detail than the current radar or cabin camera can provide today. The radar is located in the same location as the current version, directly above the rearview mirror.
Classify Passenger Size
This new radar has several new safety-focused features, and they’re all quite exceptional. First off, the radar will detect and classify passenger size to determine which airbags to deploy dynamically. That means that if a shorter individual is sitting up front, the dashboard airbag may not activate - but the curtain airbag will.
That will reduce injuries in impacts from airbag activation while also reducing repair costs by not activating unnecessary airbags. By having a better idea of the passenger’s size, height, and weight, the vehicle can also better determine when to activate the airbag.
Children Left in Car
But that’s not all - because of that classification system, the radar can differentiate an adult passenger from a baby or child sitting in the second row - and automatically make the necessary dynamic safety adjustments.
The cabin radar will also detect heart rate and breathing, and Tesla will automatically send a reminder through the Tesla app if it detects a child is left unattended in the vehicle. If this occurs, the vehicle will perform a variety of functions, the first being to turn on the HVAC system and send you a reminder. And if that’s not enough - in the case of an emergency, your vehicle will automatically call emergency services for you and report its location.
It’s important to note that while vehicles outside North America have eCall capabilities, in North America, they cannot call 911 unless a phone is connected to the vehicle via Bluetooth. We hope that Tesla can contact 911 via an alternative method or add eCall capabilities to these vehicles.
While the refreshed Model Y will be shipping in March, this new radar and its associated features won’t be available immediately. Tesla intends to activate these new safety features in Q3 2025 - so sometime in late summer or early fall. We’ll dive into this new feature once it’s available later this year.
A member of Tesla’s AI development team, Kalena Brown, took to X to mention that an update is on its way for AI 4 vehicles on older FSD V13.2 builds.
It seems that Tesla has caught an issue that has been preventing vehicles from safely updating from FSD V13.2.2 to newer builds such as FSD V13.2.4 or V13.2.6.
The Bug
Tesla usually catches these issues early in testing, but sometimes, they make their way out into the wild, necessitating a stop to a rollout. In this case, the rollout was likely halted to prevent this issue from spreading to other vehicles.
There have been a lot of comments on social media that users haven’t seen an update since late December or early January. While that’s not completely abnormal, this update, version 2024.45.25.5 includes an issue that prevents it from being updated.
Please be patient! Found an issue specific to that update path, but fix is coming soon
Many folks on older builds also waiting and we're working hard to get everyone covered 🙂
Brown says that Tesla is aware of the issue and is working hard to get a build with the fix released soon. It may be a couple of weeks before it’s ready, but you can expect Tesla to roll this one out slowly to make sure the issue is addressed.
The issue appears to be specific to FSD V13.2.2, so anyone on another update should not be affected. Keep an eye out on our feeds - and we’ll let you know once the update is released.
