What is the primary use of such tape? Where can
one buy it? How does it work?

There is a trend in kids' clothing to stitch such tape to arms
or back etc. This acts like the highly reflective surface of
some road signs in its directionality.
I noticed the local auto supply had white and red adhesive
versions on offer locally.

There was a fairly recent thread on Tap-l about making
'cat's eyes' type reflector planes which may also be somewhat
relevant.
Here the motivation was to stick glass spherical balls onto
a backing sheet.
I assume that two or three internal reflections were desired
and the motivation may have been the 'rainbow' effect,
but I can't recall.
