When a robot takes the wheel, who's in charge?

"In an email, Lin writes: "If you can see that some accidents are unavoidable, even by robotic cars, then manufacturers need to make some decision in those scenarios. Any time we make a judgment to hit 'x' in order to avoid 'y', we're making a value or ethics decision. Manufacturers would probably love to have their cake and eat it too - to create autonomous machines but to not take responsibility for them. But that's just wishful thinking.""
