Whose Life Should A Self-Driving Car Save?

When you get behind the wheel, you make hundreds of conscious and unconscious decisions as you drive like, how fast to go, when to swerve missing a squirrel or a cyclist, or when to change lanes.

But in the case of self-driving cars, it's an algorithm that makes those kinds of decisions. And those algorithms are programmed by humans who consider this fundamental question: In the case of an unavoidable accident, whose life should your car save?
