Self-driving car dilemmas reveal that moral choices are not universal

"Bryant Walker Smith, a law professor at the University of South Carolina in Columbia, is sceptical that the Moral Machine survey will have any practical use. He says that the study is unrealistic because there are few instances in real life in which a vehicle would face a choice between striking two different types of people. “I might as well worry about how automated cars will deal with asteroid strikes,” Walker Smith says."
