Suicidal people wouldn't typically try to take their bicycle and their shopping with them. But honestly, the reason she was there isn't really important. The reason the Uber couldn't avoid her is a far more important question in terms of where we go from here. It should have detected her as a potential hazard. It should have been prepared to stop. It shouldn't have been exceeding the speed limit.

A good driver will look back at what they did after an accident to see if they could have done anything to prevent it, even if they weren't at fault. Uber need to do exactly the same thing. Fortunately, unlike a human driver, they have significantly more data than an adrenaline-fuelled mind and some grainy dashcam footage to work with.
