It’s not a philosophical discussion. It’s a practical discussion. The practical reason we want self driving cars is for them to be better drivers than us. Looking further down than we do, undistracted, not tired, not in a bad mood, making faster better decisions than us, doing a better job of never getting in a Trolley in the first place.
They are better calculating engines than us.
Some of the calculations involved in driving involve moral values. The calculating engine would have to assign these a quantity. I believe this is unavoidable in designing headless cars. You seem to disagree. That would put our discussion at an impasse. Thanks for your replies.
