"In my opinion, If the autonomous car is out of control, then by definition, even if it can make a decision on who to kill, it can't actually control the vehicle to take aim."
My guess would be that an autonomous car gets out of control of it's AI by the latter overloaded with conflicting information and rules so that in order to ditch the lot it needs an emergency routine to follow. I suspect they're all loaded up with a secret "kill the lone pedestrian" function and that eventually it will be triggered where the overload arises in an entirely innocuous situation.
After all the emissions cheating stuff would you really believe it would be beyond the car manufacturers' inclinations?
