While the rise of self-driving, autonomous vehicles promises to dramatically reduce the number of traffic crashes, some accidents will still happen - and in those cases the cars themselves will choose how to react.
This is already leading to some confronting moral and ethical dilemmas.

Think about this, you're in a self-driving car and, after turning a corner, you are on course for an unavoidable collision with a group of 10 pedestrians. Should the car swerve to the side into the wall and sacrifice you, the sole occupant ? Or should it make every attempt to keep you safe?
Jean-Francois Bonnefon from the Toulouse School of Economics has published a new paper on the subject, he talks to Kathryn Ryan.
