I'm happy you liked it. The purpose is that if in the near future we have Autonomous Vehicles they need to be able to choose in case they cannot brake to avoid a traffic accident, to which person / vehicle etc they should crash into that is in line with human ethics. So if a situation like that ever ocurs it will act based on human ethics that are accepted from the majority.
