Your last graf implies that there was some nefarious favoritism that gave a turbo boost to Seattle's 2nd Ave bike lane project, due to the connectedness of the woman killed shortly before it took effect.
If you are referring to the well known tragic death of Sher Kung in August 2014, just before the September 2014 scheduled opening of the 2nd Ave bike lane, you are very wrong. The project had been underway long before that.
