It looks like any entry of the car into the crosswalk would be illegal at that point. RCW 46.61.235, "Crosswalks", states:
> (1) The operator of an approaching vehicle shall stop and remain stopped to allow a pedestrian, bicycle, or personal delivery device to cross the roadway within an unmarked or marked crosswalk when the pedestrian, bicycle, or personal delivery device is upon or within one lane of the half of the roadway upon which the vehicle is traveling or onto which it is turning. For purposes of this section "half of the roadway" means all traffic lanes carrying traffic in one direction of travel, and includes the entire width of a one-way roadway.
The street it was turning and/or veering into is a one-way street abd so the entire width counts as "half of the roadway" and thus any pedestrian in the crosswalk counts as being "upon or within one lane of the half of the roadway upon which the vehicle is traveling or onto which it is turning".
You can only drive into the crosswalk if it is a two-way road, no pedestrians are in the part of the crosswalk on the side that you are driving, there are at least two lanes going the other way, and none of the pedestrians on the other side are in the lane on that side that is adjacent to your side.
