Context is when you are
not using GPS. (Personally I despise being talked at by a computer for an hour, especially one that's bad at directing a driver.)
With paper maps, you can just look at them -- a single page, no pinch zooming or scrolling! -- to see what exit is appropriate for your destination. Not possible with Google Maps -- you either have to zoom in until the exit ramp fills the screen, or make up a fake address near where you're going to get directions which you then have to read through to find the relevant exit. It's a needless frustration when I'm in a hurry and just what to know what exit serves town X.
