Why the "trolley problem" is the wrong way to think about AVs

The "trolley problem" sets up a quandary: whether to let a trolley stay the course and hit numerous people, or redirect it and hit just one person. Recently, researchers have designed similar thought experiments around AVs.

Why it matters: AVs are being taught to drive safely and avoid harm entirely, just as human drivers are. But media coverage of these experiments, which assume unrealistic expectations for AV technology and suggest that AVs really could face such choices, may be contributing to public distrust in AVs.
