In the case of a large animal jumping directly in front of an automated car, what will the car do? Plowing straight in can likely be the best option as cars are built to protect the occupants the best in a head first collision. Trying to evade could put the car in a head on collision with another car on the other side of the road or onto a sidewalk, off of a precipice, into a building/tree/lamppost etc.
There was just a show on Horizon where they briefly mentioned situations where there is no way of avoiding an accident but didn't really explore how a computer could handle a moral decision. Hit the school bus full of kids not wearing seat belts or the massive Escalade SUV with one occupant surrounded by 8 airbags?
