The trolley problem (Relevant to autopilot mode in cars)

Humans have driven cars for a century now and animal-driven vehicles for millennia before that. I have yet to find a single documented case of the trolley problem occurring in real life with a vehicle. This simply is a problem which does not exist.
"Suppose that a judge or magistrate is faced with rioters demanding that a culprit be found for a certain crime and threatening otherwise to take their own bloody revenge on a particular section of the community. The real culprit being unknown, the judge sees himself as able to prevent the bloodshed only by framing some innocent person and having him executed."
In the heat of the moment, what seems like a plausible bargain threatens to reveal grotesque details amid the wreckage.
So, the trolley problem itself usually becomes most interesting when inspecting the identities of any casualties. e.g. What about famous people? What about small children?
In this case, the scenario becomes threatening with the possibility of proving that the condemned was sacrificed only to placate mob rule. e.g. What if the real criminal is found later, somehow?
Acting with a tendency to ignore the postmortem consequences is probably how a machine will operate. They don't have reputation. They don't consult emotion to inform their decisions.
A machine might not question which teddy bear was the most favorite teddy bear, when organizing a garage sale.
