The lives each car would have the most effect on would be those inside of it.
I disagree. The driver of a car is much less in danger than a pedestrian.
No one pedestrian is more likely to die as a result of an accident involving a particular car than the owner of that car, though, which I think is what Cube meant.
When a collision is unavoidable, should a self-driving car try to maximize the survival chances of its occupants, or of all people involved?
