I don&#x27;t understand why this keeps coming up. I have never seen or even heard of a driver getting into a situation where there&#x27;s any sort of moral dilemma in how they react. There&#x27;s always an obvious best answer or a bunch of equivalently good answers.<p>For the one-in-a-trillion cases where this is not true, it&#x27;s OK if the car reacts sub-optimally. It will still be <i>vastly</i> better than human drivers, who frequently react sub-optimally in unambiguous situations.
