Well....it was ten at night, and it could have been in a gap in the streetlights. Odds are the "safety" guy didn't see her either. I had a friend hit somebody on his motorcycle that time of night not far from where this happened.
If you ride, you are better off to assume that you will not be seen. I could write a book of incidents where car drivers did stupid things that only avoided killing or maiming me because I expected them to do the worst. As a rider, it is difficult to not take on a hostile attitude, some of the maneuvers are so dangerous to you. Only observing that people will do the same in the presence of other 4 wheeled vehicles will keep that paranoia at bay.
As for 'safety drivers', no one not involved in operating the vehicle will be 'up to speed' on what is going on outside of it. You have added in steps which slow reaction time, in that they have to realize there is a problem AND realize that the AI isn't responding correctly to it before taking over. If they were driving, one step is eliminated, and the reaction time is shortened. Add in the complacency of letting the car drive, and that lag is increased. Have someone step/run out between parked vehicles, and there isn't sufficient time to react.
WHile this tech may be good enough for limited access roadways/lanes, Frankly, I do not see it ever being able to anticipate and react to every possible situation when dealing with humans in the environment.
If you don't want to drive, call a cab, hire a chauffeur, or take the bus....
