Society will not tolerate a robocar that cheerfully kills our children to avoid some inconvenience to its occupants.
One might think that we're not talking about inconvenience, but we are, because after all any car may be driven slowly enough to avoid killing children in the road. A particular robocar that is not driven that slowly (which, frankly, would be all useful robocars), must avoid killing children in the road above all other priorities, including the lives of passengers. A VW-like situation in which this were discovered not to be the case, would involve far more dire consequences for the company (and, realistically, the young children and grandchildren of its executives) than VW faces for its pollution shenanigans.
