7. Summary

Self-driving cars have evolved from early radio-controlled prototypes to sophisticated AI-powered vehicles capable of navigating complex urban environments. Key experiments, such as the DARPA challenges and the development of vision-based navigation, laid the groundwork for today’s commercial deployments. Recent breakthroughs in deep learning, sensor fusion, and simulation have accelerated progress, while regulatory and societal challenges remain. The field is taught as an interdisciplinary subject, combining engineering, computer science, and ethics, and is increasingly accessible through both formal education and online resources. Compared to fields like exoplanet discovery, self-driving cars have a direct impact on daily life, reshaping transportation and logistics while raising new questions about safety and regulation. Continued research and education are essential for realizing the full potential of autonomous vehicles.
