As a pedestrian I follow the laws of gross tonnage. A car or truck or even a bicycle will usually knock down a pedestrian.
As a former motorcyclist I know what is like to not be seen.
As a former bicyclist I know what its like to get sideswiped.
As an automobile operator I too, have avoided accidents with pedestrians, M/C’s, bicyclists, skaters, bigwheelers... who seemingly came out of nowhere! And who themselves, were not followers of the laws of gross tonnage.
I don’t know anything about perceptual or intentional blindness ,
but I think a lifted pick up with large mirrors would make it
difficult to see a shorter person immediately in front
of the vehicle.
How long till the effort to restrict pick up mods?
Been there. Looking left and right while at a stop sign, I have found looking only once is not enough for certainty. Twice before moving and then again before total commitment.
All can be accomplished without significant delay and much greater safety, and helps to avoid the failure to see, issue.
I drive slowly in lots, always looking, and sometimes a person just matches the angle of approach and speed, and stays in my A pillar blind spot almost until it's too late. It's a bigger issue on the driver side for me, as the pillar is closer to me, and thus consumes a bigger part of my field of vision.
