A self-driving car is speeding down a busy road when suddenly a group of pedestrians appears in its path. The car has a split-second to decide between two horrific options. Should it plow down the unwitting pedestrians or swerve into a concrete barrier with the likelihood that occupants in the car may be killed?
What if the pedestrian is a woman with a stroller? Does that change the moral calculus? Or what if the occupants of the car are mostly young children while the pedestrian is a single jaywalker breaking the law? Or an elderly man, possibly disoriented?
