Testing Tesla's AI Driver: Evaluating the Occupancy Network

Introduction

Today, We Are going to Delve into the fascinating world of Tesla's AI driver testing. Specifically, we will be examining the capabilities of Tesla's occupancy network – a cutting-edge technology that aims to enhance object recognition and improve overall safety on the road. In this article, we will conduct a series of tests to evaluate the efficacy of Tesla's occupancy network, benchmark its performance, and explore the potential for future advancements. So, buckle up as we take a deep dive into the world of AI-driven vehicles.

Benchmarking the Occupancy Network

Before we commence our tests, it is essential to set a benchmark for Tesla's occupancy network. This will provide us with a baseline against which we can measure the network's performance and track any improvements. The occupancy network is designed to detect and control for objects on the road that it may not fully recognize. By generating a cuboid map of the surroundings, the network can identify occupied spaces and predict the movement of these objects, allowing the vehicle to respond accordingly. However, the extent to which this technology is currently employed remains unclear. With AI beta version 10.69 being the first known version to utilize these networks, we will examine their current efficacy and assess the potential for further enhancements.

Overview of Tesla's Occupancy Networks

Tesla's occupancy networks were showcased during AI Day 2, revealing their ability to Create a comprehensive map of the surrounding environment. These advanced networks render even the most intricate details, such as stabilization arms protruding from a truck. The networks can also accurately predict the movement of objects, enabling the vehicle to adjust its position and speed accordingly. With this demonstration highlighting the substantial progress made, it is evident that these networks have the potential to greatly enhance autonomous driving capabilities.

Detecting and Controlling for Objects

The primary objective of Tesla's occupancy network is to detect and control for objects on the road, contributing to safer driving experiences. Our initial test involves placing a piece of cardboard in the middle of the road – a simple Scenario that serves as a starting point. As we observe the vehicle's response, it becomes evident that there is room for improvement. While the network initially plans an appropriate path around the object, it ultimately fails to avoid it, running over the cardboard at high speed. This unexpected outcome necessitates further investigation to determine the limitations and areas of refinement for Tesla's occupancy network.

Improvements in Occupancy Networks

Acknowledging the limitations observed during our tests, it is worth mentioning that significant improvements are on the horizon. Tesla has expressed its commitment to enhancing the performance of occupancy networks, promising substantial advancements in the near future. These forthcoming updates hold the potential to address the Current shortcomings and significantly bolster the vehicle's ability to detect and avoid obstacles. As we progress through our tests, we will actively assess the impact of these improvements to gain a comprehensive understanding of the occupant network's capabilities.

Testing Tesla's AI on Various Objects

To thoroughly evaluate Tesla's occupancy network, we proceed to conduct a series of tests involving different objects placed on the road. These tests aim to gauge the network's proficiency in recognizing and responding to various scenarios. Let's delve into each of the tests:

6.1 Cardboard on the Road

In our first test scenario, we place a piece of cardboard upright in the middle of the road. This straightforward test allows us to assess the vehicle's ability to detect and avoid a simple obstacle. However, the results are less than ideal, with the vehicle ultimately running over the cardboard despite initially planning a path around it. This raises concerns about the network's decision-making processes and reinforces the need for further refinement.

6.2 Empty Star Length Box

Continuing our examination, we introduce an empty star length box as a more challenging obstacle. Its lower height and similar color to the road make it harder to detect. Once again, the occupancy network fails to avoid the object, choosing to run over it instead. This outcome highlights the network's struggle to adapt to different object types and raises questions about the variables it considers while making decisions.

6.3 Flipped Cardboard Box

To explore the impact of object height on the network's performance, we flip the cardboard box on its side. This ALTERS the object's profile and presents the network with a distinct visual challenge. Surprisingly, the network struggles to determine the object's identity, initially recognizing it as a trash can before mistaking it for a cone. While it eventually navigates around the object, there is room for improvement in terms of recognizing and responding to variations in object orientation.

6.4 Testing Object Height

Building on our previous test, we theorize that object height may be a crucial factor in the network's decision-making process. To validate this hypothesis, we attempt to place my microphone arm box, which is taller than previous objects, on the road. Strangely, the network fails to control for this object, potentially indicating a minimum threshold requirement that was not met. Our test results strongly suggest that both height and width play significant roles in the network's ability to detect and respond to objects effectively.

6.5 Wheel in the Middle of the Road

In this test, we introduce a wheel in the center of the road, challenging the network's object recognition capabilities. Interestingly, the network's visualizations accurately depict the object throughout the test. However, its decision-making processes remain inconsistent, with the vehicle occasionally deviating from its planned path at the last moment. Although the network demonstrates some improvement, further optimization is needed to ensure more reliable and decisive responses.

6.6 Rolling Wheel Test

Taking the tests a step further, we Roll a wheel in front of the vehicle to evaluate the network's ability to respond to objects in motion. The initial results are encouraging, with the network displaying the object consistently and even mentioning a lane change to avoid a potential blockage. However, when the wheel is thrown later in a faster motion, the network fails to render the object in time, potentially leading to a dangerous situation. This discrepancy underscores the need for improved real-time object detection capabilities.

6.7 UFO Testing with Window Shade

In an amusing yet insightful experiment, we simulate a UFO sighting by having my wife hold up a window shade to obstruct herself and create a reflective surface. This test aims to assess the network's ability to detect humans even when their visibility is hindered. To our surprise, the network accurately identifies her as a human, demonstrating its remarkable capacity to perceive and respond to obstructed objects. This capability bodes well for scenarios where traditional object recognition might pose challenges, such as during holiday seasons when humans dress up in non-human costumes.

Evaluating the Results

Based on the series of tests conducted, it is evident that Tesla's occupancy network exhibits a mix of promising advancements and areas in need of improvement. While the network showcases impressive object recognition capabilities, particularly with humans, it falls short in consistently avoiding certain objects. The network's decision-making processes in real-time situations remain a concern, and improvements are necessary to ensure the utmost safety on the road.
