I've begun to accept that I am rather missing the old road atlas.
I mean sat navs are great when you are on your own, trying to get to a destination you don't know in some busy central city. How many times have I been on my way to talk at a school, got in the wrong lane and found myself back on the ringroad that I came in on... and ended up 30 minutes late, while the assembled junior classicists got more and more restless, and the teachers more anxious, wondering when I would turn up? (This was the era before mobile phones too.)
But honestly, if you've got a passenger, and if s/he is a reasonably competent atlas reader, then s/he's a much better bet than the electronic voice. "You're going to be turning right in a bit, so I'd get in the right hand lane" is a lot more engaging than the damn woman who intones in her cyborg tones "prepare to turn right".
In fact, I've ended up pretty aggressive against the disembodied voice in my car (even if I do still use it.. partly because -- of course -- we've thrown our atlases away).
