Re: Premeditated
By my reading of the logs, the system also incorrectly estimated the object's path and thought it wasn't going to get in the way (until it was far too late).
If I had to wildly hypothesise: the repeated re-categorisation of the object screwed up it's trajectory analysis, and *that* happened because, as you said, it wasn't trained around people crossing roads away from pedestrian crossings.
That's still mind-blowingly bad planning. This is pretty much negligent homicide.
