In other words, the AI behaved very much like a Human driver.
Cyclists and pedestrians are often regarded as static objects to be avoided rather than dynamic objects that have a very significant risk of moving into your path (Or you moving into theirs re cyclists at intersections)
Like a human driver, The AI didn't expect her to just step right out in front of it and by the time it realised (Again, just like a Human driver) that she was actually in the vehicles direct path, it was too late to stop.
