Imagine you're in your car on a mountain road and your computer is in complete control. And your vehicle is driving along perfectly safely.
Coming the other way is a driverless coach full of schoolchildren, again moving in perfect safety.
As you approach each other - horrors! - a non-mechanical disaster happens to the coach. Perhaps a multiple puncture. Perhaps a huge rock suddenly falls into the road immediately in front of it.
Now, you're on a narrow mountain road. The computers in both vehicles start talking to each other. (This is taking place in a fraction of a second.) They work out between them that to avoid a collision, one of the two vehicles has to leave the road, which means it will go over a steep cliff. So now the computers are discussing "damage limitaton". You're on your own in the car and the coach is full of kids.
Through no fault of your own, you are dead.
Cheerful thought, isn't it?
