Yes, she crossed where it's forbidden to cross, but...
These links put the incident in a very different light to the dark dashcam footage:
The road widens at this point, although you can't see that in the original dark dashcam footage.
The lady with the bike was crossing her *fourth* lane by the time she came to grief.
- From the pedestrians' perspective, it's a lot harder to time/judge how fast a car is coming when she left the kerb so much earlier. It was not a wise place to cross (and is forbidden by signs) - but the her error in judgement of timing is much finer / more forgivable than other reports or a view of the dashcam alone would suggest. As pedestrians, we've all made similar misjudgements a handful of times in our lives. The car would only have had to slow by 5-10 miles per hour a few 10's of yards earlier, and the lady would have made it across the road; it would have been close, but she'd've been ok.
- As far as the car's navigation cameras / systems are concerned she most definitely did not "step off the curb into the path of the car" - she'd already crossed 3 lanes, and should have clearly been identified, and identified as being on a collision course.
The car definitely should have been able to prevent this tragedy.
