It might begin very soon

One of the biggest hurdles to automated driving are ethical decision trees. What will the programming be when the vehicle is faced with multiple bad outcomes? Will it be programmed to protect the vehicle at all costs, keeping it out of the ditch and running into a child instead? Will it be programmed to go the other way and veer into the ditch and miss what it thought was a child, but was actually a bag of trash in the middle of the highway possibly careening out of control and crashing into homes, businesses etc? There is a lot of information available on this problem and it is scary to realize there may actually be computer code that makes the decision to deliberately kill you in an effort to protect someone else.
