We know that level of safety provided by a driver is possible. But higher level is for now just speculative, even though additional sensors exist. You'd be punishing developing technology for not achieving the perfection yet.
Humans don't "see" stuff just because the light is entering their eyeballs. A human driver could have been checking their mirrors, the radio, distracted by another pedestrian on the other side of the road, and or just plane not registered the person. The motorcycle safety course teaches you to not use eye contact as a means of determining that a driver "sees" you. That's right, an attentive driver actively looking for on coming traffic during daylight can "see" right through you.
