Can Self-Driving Cars be Modeled for Morality?

Imagine a self-driving car making its way down a foggy road that is suddenly blocked by two separate obstacles – is one of them an object? A person? An animal? Would the autonomous vehicle make the right split-second decision on which one to spare? Can algorithms be used to make decisions in scenarios where harming human beings is possible, probable, or even unavoidable? A study from the Institute of Cognitive Science in Germany’s Osnabrück University suggests that autonomous vehicles have the capability to address moral dilemmas in road traffic.
