> Elaine Herzberg, 49, was walking her bicycle outside the crosswalk on a four-lane road in the Phoenix suburb of Tempe about 10 p.m. > Tempe Police Chief Sylvia Moir said that from viewing videos taken from the vehicle “it’s very clear it would have been difficult to avoid this collision in any kind of mode (autonomous or human-driven) based on how she came from the shadows right into the roadway." This seems like an unfortunate accident, but it's not at all clear that the car was at fault or that it could have done anything to prevent it. There was even a human behind the wheel and they didn't react in time either.
