Drivers who kill pedestrians or cyclists don't consciously decide to murder them (at least not in 99.99% of cases), they do it out of negligence - opening a door without looking into the mirror, turning right at an intersection without looking for pedestrians or cyclists, not stopping at pedestrian crossings etc. etc.

I'll rephrase, humans have some incentive to avoid negligence despite being imperfect and occasionally being negligent anyway. Robotaxis are imperfect and have no such incentives.
