I dont 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?
People are idiots and assume you see them when you dont
Most newer trucks are not the best for close quarters driving. I drive a standard Suburban. It also has large mirrors and pillars which take up a lot of forward sight. I tend to stick to the back of parking lots and negotiate into and out of parking spaces very slowly and carefully using all my mirrors and my head constantly on a swivel and always making sure I can pull forward out of the space if possible.
That and Ergonomics.
