Driverless cars: Who gets protected?
Driverless cars pose a quandary when it comes to safety. These autonomous vehicles are programmed with a set of safety rules, and it is not hard to construct a scenario in which those rules come into conflict with each other. Suppose a driverless car must either hit a pedestrian or swerve in such a way that it crashes and harms its passengers. What should it be instructed to do? A newly published study co-authored by an MIT professor shows that the public is conflicted over such scenarios, taking a notably inconsistent approach to the safety of autonomous vehicles, should they become a reality on the roads. In a series of surveys taken last year, the researchers found that people generally take a utilitarian approach to safety ethics: They would prefer autonomous vehicles to minimize casualties in situations of extreme danger. That would mean, say, having a car with one rider swerve off...
