Also, a question remains of whether the law should dictate the ethical standards that all autonomous vehicles must use, or whether individual autonomous car owners or drivers should determine their car’s ethical values, such as favoring safety of the owner or the owner’s family over the safety of others.[13] Although most people would not be willing to use an automated car that might sacrifice themselves in a life-or-death dilemma, some[who?] believe the somewhat counterintuitive claim that using mandatory ethics values would nevertheless be in their best interest. According to Gogoll and Müller, “the reason is, simply put, that [personalized ethics settings] would most likely result in a prisoner’s dilemma.”[50]
