Blind spots, LOL.
My 11th grade business law teacher
(
who retired to AZ and joined Sheriff Joe's posse! )
did not merely warn us callow youts that we think should twice
about sticking one of those
translucent <name of college>
decals on our rear windows. Because cops have been pleased to
issue "obstructed vision" tickets for them.
He even warned us not to hang our HS graduation tassel from our rear-view mirror.
Because cops loved handing out obstructed vision tickets for
that.
"Your Honor, defendant killed a dozen nuns escorting two dozen kindergartners
because his vision was obscured by the frayed piece of string that he negligently dangled
from his rear view mirror, thus blocking his view of the entire crosswalk".
