Despite my love for technology, I have somehow never wanted a GPS navigation system in the car. That's possibly because I have a good ability for working out my ability to get somewhere (both before and during driving).

More than likely, though, it's because I don't like being under the control of a piece of technology. I know they are not infallible (and for that we can only blame humans - machines are only as intelligent as the person that programmed them), and even if they were, computers suffer from a distinct lack of flexibility. At the weekend I visited my parents - by the time you reach the outskirts of the town they live in, there are three or four alternative routes you could follow to get to the house, and some of them, despite most route planners, are quicker and easier than those offered. In that situation, I don't want a voice telling me I'm going in the wrong direction and that I should turn left at the next turn.
