Why program the car to choose to crash in to things? This makes no sense. What if the sensors are wrong and there was no second car? It seems more prudent to just program it to avoid crashing in to things, even if that is an impossible goal in some circumstances. In those cases, a better fallback would be to reduce velocity, and keep the car on the road or road shoulder perhaps?
