Will your car decide to kill you?

A self-driving car made headlines last summer when its human'driver' was killed in an accident. Both car and driver had failed to spot a lorry across the road ahead, because the whiteness of the truck was too similar to the sky. But what about if the human driver had seen the lorry, but could only avoid it by swerving into another car, or a pedestrian? Would it then have been'right' for the car to override the driver and allow the crash into the lorry, potentially saving other'innocent' lives? I did a survey on these kind of questions at Moral Machine at MIT, and it definitely got me thinking.
