AI ethics: If a driverless car were to take a life, whose should it be?

Slowly but surely, work on self-driving cars is progressing. Crashes still happen, tragic accidents come to pass every once in a while, and autonomous vehicles still make stupid mistakes that that the most novice human drivers would avoid. But eventually, scientists and researchers will teach our cars to see the world and drive the streets on a level that equates or exceeds the skills of most human drivers. Distracted driving and DUI will become a thing of the past. Roads will become safer when humans are removed from behind the steering wheel.
