13、ners of automated cars dont have that luxury,since they do have the time to get it right and therefore bear more responsibility for bad outcomes.”-Patrick Lin,The AtlanticThe Trolley ProblemA trolleys brakes have failed.You are controlling the signal switch.If you do nothing,five people will be kill

14、ed.If you activate the switch,only one person will be killed.What do you choose to do?Critical distinction:Allowing death versus causing death?A classic thought-exercise in ethicsUtilitarian AnalysisWeigh the pros and cons of each potential outcome to determine the net change in overall welfare.Pick

16、mitted.A truly accurate analysis may require valuing one human life over another.The“least bad”outcome may still result in the loss of life.Another Problem:ConsequentialismWithout complete information and the gift of hindsight,a decision that results in a net gain of welfare in the short run may tur

18、an increase in pedestrian and cyclist deaths.Great news for some people,bad news for others.An ethical conundrum:Can we accept an increase in the death rate of certain groups of people if it means a decrease in the overall death rate?Random Outcome Generator1.Swerve to the right,potentially killing
