The whole ethics framework debate is a straw man (computer) argument. It's patently obvious people don't make those split second judgement calls. The real reason the Germans are on sound moral grounds is autonomous cars are nowhere near commercial prime time on sunny day clear traffic straight highways. Dirty sensors, unpolished code with bugs, proper reliable extraction of features, sensor failures, intelligent prediction of object locations, prediction and proper avoiding of road hazards, and many more things still need to be ironed out. Problems creep up where a driver may have only a second to take over after the AI bails - complete bullshit that a human can hyper concentrate over the controls and take over in one second properly three hours and twenty six minutes in.
How the fuck do you justify putting people's lives at risk with your crap box wanna be AI? I want self driving cars as much as anyone not employed in the commercial driving industry. But not when any jackass car with half capable systems risks everyone's life. Honestly it needs to be banned in the United States on public roads. Wanna play? Pony up for a closed course before risking people's lives. If you think moral decisions are the barrier to AI cars you haven't the foggiest idea what the actual challenges are.
