Don’t put words in my mouth. I addressed the scenario you posed which said nothing of legality or not. Generally a pedestrian has right of way so legal would be the default assumption.

To the point of your post, I don’t know if she was legal or not. I haven’t read the article but obviously I’ll have to. Did she hand signal? Do we have video of that or are we taking the driver’s word for that? An unsafe lane change would put her at fault.

Edit: absolutely nothing in the article to indicate she failed to signal.
