Apropos of the whole OMG-GPS-is-going-to-fail thing, the Grauniad’s Tim Dowling has some advice for drivers who might suddenly have to do without their in-car navigation systems, in the form of a FAQ for paper maps. Some examples:

I need to get to Redditch. What do I press? Locate “Redditch” on your map and press it with one finger. Find your current location and press it with your other finger. Now find an unbroken line that connects the two fingers. That is your “route.” You are ready to begin your journey.

I’ve been driving for 40 minutes and it still hasn’t said anything. Should I just keep going straight? The map will not issue instructions. It is up to you to compare the route on the map with information gleaned from your surroundings, and drive accordingly.
