Recent advances in autonomous vehicles promise to revolutionize the transportation system. This perspective has led to new research on a number of open questions, such as how the self-driving system should behave in unavoidable crash situations. Our study aims to contribute to this investigation. In most ongoing research, this question is presented as a moral dilemma, drawing on established research on the trolley dilemma. However, more recent studies have shifted the focus from morality to risk analysis. We investigated the dual contribution of moral judgment and risk analysis in subjects facing dangerous situations. To this end, we use virtual reality to recreate a driving situation that allows subjects to immerse themselves in the road environment. Our results show a strong dissociation between quick decisions, when risk analysis seems to suggest the best choice, and conscious decisions, when proper moral judgment is at stake.

自动驾驶汽车的最新进展有望改变运输系统。这种观点导致人们对许多悬而未决的问题进行了新的研究，例如，自动驾驶系统在不可避免的碰撞情况下应如何表现。我们的研究旨在为这项调查做出贡献。在大多数正在进行的研究中，这个问题是根据对推车困境的既定研究提出的，是道德上的困境。但是，最近的研究已将重点从道德转向风险分析。我们调查了面对危险情况的主体中道德判断和风险分析的双重贡献。为此，我们使用虚拟现实来重现驾驶情况，使主体能够沉浸在道路环境中。我们的结果表明，快速决策之间存在强烈的分离，
