              but overall, the automation saved countless hours of
            manual name expansion for the minor cost of having to deal
            with a very small number of largely regionally-isolated edge
            cases.


        Can someone explain the original point of name expansion? Is it
        so that devices that give audio directions using text-to-speech
        can read fluently? Or was it really all about "saving time"?

        Because there are other use cases where expanded names are not
        desirable, particularly in cartography. When map or screen real
        estate is minimal, expanded names can be downright detrimental
        to utility.


    Sounds like a problem for the renderer to solve.  It's possible for
    renderers to easily create abbreviations when full words are not
    desired, but impossible for automated translation and renderers to
    expand abbreviations accurately.


I *guess*, but that seems unrealistic expectation to put on GPS hardware
manufacturers. Particularly if name expansion is inappropriate in one
town, but perfectly appropriate in another, and usual practice is to
load a large area (like a whole state or region) into a GPS device. How
woud a device renderer know to even try to distinguish across community
lines?

it wouldn't be the device renderer (in most cases) but the the tools used to process the data - for example, mkgmap would do the shortening for garmin maps

 From the user perspective it would be nicer if the names in the data
set correspond to the actual street sign names. In Portland the street
name is "Tillamook" and if I am on "NE Tillamook" that just helps me
know the quadrant of town. "Northeast" on it's own doesn't tell me
anything if I can't see the rest of the street name.

This example feels more like "tag for reality", vs "tag for the
renderer" argument, and the short prefixes feel more like reality in
Portland, but maybe that's just me...

I do see the value if text-to-speech is the real reason this was done
though.
