Rule one, save all your passengers. Nobody would buy a car that has the death of its passengers as an acceptable scenario and Jeff from marketing will be on my ass otherwise.

Rule two. Kill the least amount of people outside of the car. Done.

I know this is a thought experiment but this is completely missing the point of self driving cars IMO. Sure a human can be more moral than a car, but all it takes is being distracted for a second and you killed all the babies on the pavement.
