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.

I feel you on the talking part. Especially maddening to me is where it talks over an in-progress conversation to tell us things we already know.

I now generally turn the audio part off except for alerts. I like that better, not only is it more soothing, but it forces me to engage my brain a little more.
