1. The car detected the pedestrian before the collision: "According to data obtained from the self-driving system, the system first registered radar and LIDAR observations of the pedestrian about six seconds before impact." Since the car was clocking 43 miles per hour at the time of the incident, the detection happened while there was roughly 378 feet between the vehicle and what it initially registered as an "unknown object."

2. A pedestrian walking a bike at night may have temporarily confused the system: "System software classified the pedestrian as an unknown object, as a vehicle, and then as a bicycle, with varying expectations of future travel path." The report doesn’t indicate whether or not it’s significant that the car failed to register the obstruction as a pedestrian or if this affected its expectations.

3. The car was under human control for the collision but only for the final second: "At 1.3 seconds before impact, the self-driving system determined that an emergency braking maneuver was needed. [...] The vehicle operator intervened less than a second before impact by engaging the steering wheel. [...] The operator began braking less than a second after the impact."

What follows is at the end of the linked report:

"The NTSB continues to gather information on the pedestrian and is seeking information from anyone
who might be aware of her activities before the crash. Those with information should contact the NTSB
by email at witness@ntsb.gov. Toxicology test results for the pedestrian were positive for
methamphetamine and marijuana."

IMHO the biker sounds like she used bad judgement and did not walk or bike to the crosswalk.
