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.
It does not involve moral values. Have you ever actually faces a trolley problem while driving? No of course not. The calculating engine does not need moral values, it needs to be better at paying attention than us and avoid the accident in the first place.
