Testing Tesla's Occupancy Network: Are We There Yet?

Introduction

AI-driven technologies have revolutionized the automotive industry, and Tesla has been at the forefront of this innovation. One of their latest developments is the Occupancy Network, a system designed to detect and control for objects on the road. In this article, we will test the capabilities of this network and delve into its strengths and limitations.

Tesla's Occupancy Network: Detecting and Controlling for Objects

The Occupancy Network showcased during Tesla's AI Day 2 is a groundbreaking system that can identify and account for objects that aren't fully recognized on the road. Utilizing advanced algorithms, the network constructs a cuboid map around the vehicle, highlighting occupied spaces in the scene. This map even captures objects like stabilization arms protruding from trucks, demonstrating impressive accuracy.

Moreover, the Occupancy Network has the ability to predict the movement of these cuboids, allowing the vehicle to proactively respond. For example, it can detect a swerving trailer and adjust the car's position accordingly by moving within its lane and slowing down. This level of object recognition and control sets the stage for safer autonomous driving experiences.

Improvement in the Pipeline

While the Occupancy Network has already made its debut in Tesla's FSD beta version 10.69, there are indications of significant improvements on the horizon. Although the extent of its current usage remains uncertain, Tesla's commitment to refining this feature suggests a future where the network plays a more prominent role. With this in mind, let's now explore the results of our real-world testing.

Testing the Tesla AI Driver: Benchmarking the Occupancy Network

To gauge the effectiveness of Tesla's Occupancy Network, we conducted a series of tests featuring various objects of different shapes and sizes. These tests were performed in a controlled environment, ensuring minimal interference with traffic. The goal was to observe how the AI driver would react to both simple and challenging obstacles.

Object Recognition Testing: Simple Obstacles

Our initial tests involved relatively straightforward objects placed in the middle of the road. We started with a piece of cardboard stood up on its side, expecting the AI driver to detect and maneuver around it. However, the results were not as anticipated. The autopilot abruptly changed its Course at the last moment, resulting in the car running over the cardboard.

Given the unexpected outcome, we decided to repeat the test. This time, the car did recognize the object and successfully navigated around it, demonstrating improved performance. Encouraged by this mixed result, we proceeded with another attempt, which yielded the same outcome as the Second trial. It became clear that the AI driver's response varied, underscoring the need for further refinement.

Flipped Cardboard Box: A Height Challenge

To evaluate if the height of an object impacts the Occupancy Network's performance, we set up a flipped cardboard box. Surprisingly, the network struggled to identify the object accurately, initially perceiving it as a trash can and then a cone. Despite its indecision, the car managed to maneuver around the box, showcasing adaptability.

We conducted a second trial with the same object, and this time the AI driver recognized it as a trash can and successfully avoided a collision. While the response was an improvement from the previous attempt, there is still room for the network to enhance its decision-making process.

Microphone Arm Box: Exploring Height vs. Width

To further investigate whether the network prioritizes height over width, we introduced a microphone arm box. Initially, the setup encountered difficulties, with the network struggling to determine the object's identity. Despite the ambiguous visualizations, the car ultimately navigated around the box, albeit with minor uncertainties in its path. This led us to hypothesize that the network might have a minimum height threshold for object recognition.

To test this theory, we modified the orientation of the box, placing it on its side lengthwise. This adjustment yielded more positive results, with the car following its planned path and smoothly maneuvering around the object. Nonetheless, it is worth noting that the car approached the box quite closely, leaving us somewhat concerned about potential collisions.

Challenging Obstacles: Wheel on the Road

Moving on to more demanding obstacles, we introduced a wheel placed in the middle of the road. The Occupancy Network displayed more consistent object visualizations, and the car initially followed a solid path. However, as the car approached the wheel, it suddenly Altered its course, exhibiting Momentary indecisiveness. This slight deviation was likely due to the vast number of images of wheels that the network has encountered, causing misinterpretation in this particular Scenario.

A second attempt yielded similar results, with the car deviating from its initial path upon approaching the wheel. Although the response was slightly better than the first attempt, there is still a need for more precise decision-making algorithms.

Rolling Wheel Test: Reacting to Moving Objects

To assess the AI driver's ability to respond to moving objects, we performed a test where the wheel was rolled in front of the car. Impressively, the wheel remained consistently displayed on the car's dashboard throughout the test. The vehicle recognized the path blockage and displayed a message indicating a lane change away from the obstacle. This demonstrated the Occupancy Network's proficiency in detecting and reacting to dynamic situations.

Furthermore, we attempted a more challenging scenario by rolling the wheel out a bit later. Unfortunately, the test did not yield the desired outcome, as the wheel was only recognized and displayed on the dashboard after it had crossed over into our lane. This delay highlights the need for improved object recognition algorithms to detect moving objects earlier.

Human Detection Testing: Hiding in Plain Sight

Apart from recognizing objects, the Occupancy Network aims to detect humans on the road. To assess this capability, we conducted tests involving my wife, who hid herself behind a window shade, creating a large reflective surface. It is important to note that all safety precautions were taken, including an appropriate life insurance policy.

During the first attempt, the car successfully visualized a path around the Hidden human and executed it accurately. Even with obstructed visibility, the network was able to identify her presence and respond accordingly. This promising result motivated us to proceed with more challenging tests.

Walking Across the Road: Testing Dynamic Human Detection

In this test, my wife walked across the road in front of the vehicle. The Occupancy Network impressively visualized her as a human, even with significant obstruction. The car slowed down as she approached, indicating a successful detection. However, there was a slight delay in reaction time, raising concerns about its effectiveness in scenarios where rapid action is necessary.

To further explore the network's response, my wife increased her walking speed. Although the AI driver applied sudden braking, it still managed to pass by her safely. While not Flawless, this demonstrates the car's ability to react to dynamic human movements.

Running into the Road: The Final Challenge

In the most challenging test, my wife ran into the road, mimicking a sudden and unexpected event. The AI driver impressively reacted early and came to a near-complete stop. This outcome showcases the potential of the Occupancy Network to handle unforeseen situations effectively.

Conclusion

Upon testing Tesla's Occupancy Network, it is clear that there are strengths and weaknesses in its object recognition and control capabilities. While there were instances where the network excelled in detecting humans and responding appropriately, there were also cases where it struggled with simple objects and exhibited indecisiveness.

As Tesla continues to refine and improve the Occupancy Network, we can expect significant advancements in the detection and control of objects on the road. These developments will pave the way for safer autonomous driving experiences, offering reassurance and confidence to both drivers and pedestrians alike.
