Well, anyone using a SatNav is, frankly, asking for trouble. As GSM said, "U-turn on a motorway"?! [maybe it meant at the next junction, but with those things, who knows??).
Stories abound of giant trucks being sent down tiny country lanes - and then struggling to reverse back again! -- and a friend out dogwalking almost got run down by a courier van who was using a track that isn't a made-up road, but a SatNav shows it as a road, so can have nitwits using that shortcut without looking properly.
We have nice mapbooks, and if going somewhere new, plan the route. Google prints can show general plans of a town or city, then more detailed street maps, and they can all be printed off to reference. For traffic news, use the radio so that the bulletins cut in with any late news.
I'm not surprised that tech-mad youth thinks that maps are 'old hat'. The Apprentice show, last year I think, featured groups who had that task to find a dozen or so items, at the cheapest overall prices, and report back at a given time, end of the day. They tried to use maps on mobile phones, instead of doing a common-sense thing of buying a map and planning a time-saving route. They both ended up running round town (Brighton I think it was) like the proverbial headless chickens. Neither group found the main market, where they could have quickly obtained several items!
