10 minutes later: panicky call: " Help! Where am I! I'm in a wood!' Discussion concludes that his satnav has directed him to the wrong side of the river and he is, therefore, in the wrong county. What's more, on enquiry it turned out that he did actually know where the village was, roughly - only because the satnav told him, he went another way. Why do people believe what computers tell them, so confidingly?
If he has not been eaten by beavers, I expect another call when he gets to the pub, because satnav is no use in a village that only has one postcode anyway.
Give me a map any time.
