> My humble opinion is, autodriving cars should never leave the roadway. See, the people on the road have voluntarily put themselves 'in the game'. I think this is as close to the "correct" answer for the Trolleycar problem as one can get. Even when your passenger is the Nobel winning cancer scientist and the hapless bystanders are "worthless criminals" (or whatever arbitrary utility standard we suppose society might choose). Restricting the fallout to those who choose to use autonomous devices while totally protecting "externalities" also aligns with market forces, if you believe in those. The autonomous car absolutely should kill the passengers, even if a better utilitarian outcome seems available but involving others who did not choose to play that game. And herein lies the current deep fault in all technologies (but particularly digital ones): The convenience of the few (or even the majority) is becoming an imposition on the welfare of others who do not choose or want to play that game. It is, in these terms, quite simply "tyranny".
