I think driving navigation is a great thing, but the UI is all wrong. It needs to work to understand me, to see the routes I have driven with it 100 times, and only tell me when there is something unusual I need to know, not where to turn to get to my house (or telling me "You have arrived at your destination" at my driveway.)
