Yup, even if the parking was completely removed (highly unlikely to happen without a fight and in comment from the State of CA) and replaced with segregation, there would still be issues with sight lines and increased risks of right hooks, left crosses, and conflicts at the four-way stop sign controlled intersections.
Several of the sharrows on Congress St. are installed incorrectly at the edge of the lane in spots where street parking is prohibited by the presence of red painted curbs. Those spaces work well for a place to temporarily pull to the right edge to release motor traffic to let them pass but otherwise the markings themselves shouldn’t be there. I reported it years ago to GetItDone but doubt they were ever fixed.
Not sure though per that article whether the collision occurred in that area though with the edge-installed sharrows. It’s awfully congested at times and the sight lines even out in the middle of the lane are limited by the parking. It’s sketchy to even use by car due to other motorists pulling out, often blind, into the street.
