Introduction

Almost a decade ago, tech companies made bold predictions about the future of self-driving cars. With over $100 billion in investment backing them, these companies asserted that fully autonomous vehicles would become a normal part of everyday life within five years. However, these promises have yet to be fulfilled, and even the most optimistic forecasts suggest that it will be several decades before regular consumers have access to fully autonomous vehicles.

Promises and Reality of Fully Self-Driving Cars

At present, most major car manufacturers offer driver assistance features categorized as level 2 automation. These features can handle specific driving tasks such as cruising, changing lanes, and braking. However, they still require human monitoring and focus. There are a few companies testing driverless vehicles that can navigate fully autonomously in a handful of cities. Waymo, for example, offers a driverless taxi service in select parts of Arizona. However, these vehicles have limitations and are far from fully autonomous.

The Current State of Autonomous Vehicles

The pursuit of fully autonomous vehicles is not only driven by convenience but also by the potential for trillions of dollars in disruption to the transportation industry. Companies like Uber have bet their long-term growth on this technology. Experts predict that once achieved, fully autonomous vehicles could prevent an estimated 1.3 million deaths worldwide per year caused by traffic accidents. Additionally, they have the potential to reduce congestion and emissions.

The Layered Approach to Autonomous Vehicle Technology

Autonomous vehicles operate using a layered approach to information processing. At the bottom of this stack is navigation and path planning, which is the easiest challenge to address. Navigation is accomplished using a combination of satellite-Based systems, sensors, and maps to determine the ideal travel path. Above this layer is environmental perception, which involves detecting and mapping the environment to traverse a navigational path and avoid obstacles. This is currently done using lidar, radar, and visual perception.

Challenges in Environmental Perception

Lidar navigation relies on laser technology to Create a 3D point cloud of the environment. Radar navigation uses radar systems to detect distance and movement. Visual perception, on the other HAND, mimics how humans drive by using camera sensors and artificial intelligence systems. While lidar and radar have been effective in navigating vehicles through the environment, they lack the level of cognition needed to replace human drivers. Visual perception systems, powered by convolutional neural networks, offer a promising approach but still struggle with identifying objects accurately in various conditions.

The Potential Future of Autonomous Vehicles

Despite significant funding and research, current autonomous systems still face challenges in perceiving the environment accurately. Misidentified objects and inaccurate motion inferencing can lead to collisions and deadly situations. Many experts believe that self-driving cars will not become a reality until a general AI on par with human perception is fully established. Trust in autonomous vehicles among the general public remains low, and there are doubts about their ability to reliably recognize and respond to complex situations.

Conclusion

The pursuit of self-driving vehicles has led to significant advancements in machine learning and visual perception. However, there are still significant challenges to overcome, and the safety concerns surrounding autonomous vehicles persist. The future of fully autonomous vehicles remains uncertain, and it may require a hybrid approach or dedicated rules and roadways to ensure their safe integration into society. Regardless of the challenges, the progress made in autonomous vehicle technology has paved the way for advancements in other industries as well.
