As I understand it, the law basically follows common sense anyway.
“A. The driver of any vehicle on a highway shall yield the right-of-way to any pedestrian CROSSING such highway:
1. At any clearly marked crosswalk, whether at mid-block or at the end of any block;…
No pedestrian shall enter or cross an intersection in disregard of approaching traffic.
The drivers of vehicles entering, crossing, or turning at intersections shall change their course, slow down, or stop if necessary to permit pedestrians to cross such intersections safely and expeditiously.”
And a bike using a crosswalk is a pedestrian, legally.
So, if you’re about to cross at a crosswalk, you wait until it’s safe – so a car won’t run you down because it didn’t have time to stop. If you’re already in the crosswalk, cars must yield – and not run you down.
So cars have the right of way until a pedestrian is in a crosswalk, and then the pedestrian does. And both must use proper judgment to protect themselves and the other party.
If, like in this case, a car doesn’t appear to be moving or moving fast enough to be a hazard, you can cross and then it must yield.
But I’m no expert.
