Pedestrians Crossing Improperly
My question regards the right of way of pedestrians who are in the roadway illegally, i.e. they have disobeyed a control signal or have failed to yield to traffic as per section 180. The thought came to me after watching a YouTube clip from the United Kingdom, intended to illustrate proper horn use.

This week's correspondence contained a request to explain what pedestrian signals mean. The gentleman who sent me the e-mail expressed the opinion that many people either did not know what pedestrian signals mean or choose to deliberately disobey them. Would I please explain so that they would know what to do.
Question: Please comment on the subject of when a vehicle claims the crosswalk and what pedestrians must do and not do in that situation. Pedestrians seldom wait for vehicles that have lawfully claimed the crosswalk. Sometimes they get upset with drivers and now there is conflict while the driver attempts to complete a maneuver and the pedestrian actively impedes the flow of traffic.
My university workplace has just erected signage at a pedestrian crossing leading to a parking lot and I am just trying to determine if this is in contravention of current pedestrian right of way laws in BC. I want to have all my facts before I submit a formal complaint.
Effective on June 3, 2024 a new division called Electric Wheelchairs and Mobility Scooters has been added to the Motor Vehicle Act Regulations. Division 38A defines the terms "electric wheelchairs" and "mobility scooters," designates them as personal mobility devices and creates an offence for operating them dangerously.
Question: I have been wondering about pedestrians and pedestrian signals in Vancouver. Long after their signal has turned to 'Don't Walk' - giving motorists a chance to complete a turn - they continue to fill the crosswalks like they had some kind of right of way!
