This is actually my biggest fear. I've no doubt that on average, self driving cars are going to be infinitely safer than manual drivers but if stopping for someone jumping out in front of you is going to be mandatory without any kind of override, then I suspect the practice of "car jumping" on country roads is going to become rather commonplace.
I suspect that an "ESCAPE" button will be required which will allow the car to take aggressive, evasive action rather than come to a full stop.
