The Advent of Autonomous Driving, and Ethical Questions Over the past few years, our society has witnessed the revolutionary technology of autonomous vehicles becoming a reality. The advancement of cutting-edge technology and artificial intelligence (AI) is opening up possibilities we could not even imagine. While autonomous vehicles are expected to reduce traffic accidents, enhance traffic efficiency, and decrease environmental pollution, the future this technology brings extends beyond mere convenience, confronting us with complex ethical questions. To prepare for this, it is time for us to seriously consider not just technological advancement, but also the ethical, cultural, and social challenges inherent in autonomous vehicles. One of the primary ethical dilemmas autonomous vehicles face arises from the shift in decision-making authority from humans to machines in the event of an accident. In situations with a high probability of an accident, autonomous vehicles must choose whether to save the lives of many or prioritize the safety of the vehicle's occupants. For instance, in a scenario where there are several pedestrians on the roadside, the vehicle might intentionally alter its course to minimize overall damage, even if it means risking injury to its occupants. Interesting research findings on this dilemma were recently published. A study titled 'Cross-Cultural Trust and Driving Behavior Indicators for Autonomous Vehicles,' published in the MDPI journal on March 22, 2026, clearly illustrates the complexity of this issue. According to the study, the majority of people conceptually support utilitarian design, meaning the principle of acting for the greatest good of the greatest number. However, when they themselves become occupants, they exhibit a dualistic attitude, preferring systems that protect them. This discrepancy between 'collective support' and 'individual self-interest' acts as a significant barrier in the development process of autonomous driving technology. The core finding of this research is that occupants find it difficult to fully accept a system that might not prioritize their safety. People know what the morally correct choice is, but when that choice directly affects themselves and their families, they make entirely different judgments. This is not merely a matter of selfishness but reveals the complexity of human nature, suggesting a fundamental difficulty in building trust in autonomous vehicles. It highlights the critical importance of social consensus alongside technological advancement. International efforts to address these issues are also actively underway. The European Union (EU) has already developed ethical guidelines for autonomous vehicles, centering ethical discussions on the principle of protecting multiple lives and working towards common agreements. Europe's approach emphasizes the principle that human value should be central, and 'no life should be discriminated against.' In contrast, the United States and Asian countries are also developing ethical frameworks that reflect their respective cultural characteristics. In the case of the United States, reflecting its somewhat individualistic culture, the approach is for companies to individually develop ethical guidelines and monitor the market through self-regulation, rather than detailed government control. Such differences reflect that the technology design process is not merely an engineering decision but is thoroughly influenced by culture and value systems. This is precisely what the MDPI study particularly highlighted. The research illuminates the impact of cultural context on building trust in autonomous vehicles, explaining that in collectivist cultures, designs that minimize overall societal harm may be more readily accepted. Conversely, in cultures with strong individualism, designs prioritizing individual choice and safety are likely to be preferred. South Korea is also one of the countries recognized for its world-class technological capabilities in autonomous vehicle development. Major corporations like Hyundai Motor, as well as various startups, are participating in continuous efforts to commercialize Level 4 autonomous driving. However, many point out that, unlike the pace of technological advancement, ethical standards and social discourse are somewhat lacking. Social discussions to resolve complex issues such as the ethical dilemmas of autonomous vehicles are still insufficient. Ethical public discourse and social consensus are essential to address these problems. 'Who to Save': The Boundary Between Technology and Humanity South Korea, in particular, is a society where collectivist culture plays a distinctive role. Experts believe that due to these societal characteristics, ethical standards for autonomous vehicles are likely to be designed to minimize overall societal harm. As the MDPI study revealed, a utilitarian approach can be relatively more easily accepted in collectivist cultures. However, this p
