Sat-Nags are not infallible, and nor is Google Maps.
My attempt to find Doncaster Raceourse for the ME exhibition there nearly ended with me just giving up. The venue is not sign-posted and the sat-naive (a Tom-Tom) could not plot my position rapidly enough to cope with heavy stop / go-fast traffic in a complete tangle of roads with difficult junctions very close together. At one point I found I was in the queue not for traffic-lights, but the road/rail goods terminal! I vowed I would never go again.
On another trip it made me turn off to the right into a housing-estate, needlessly, and back to the same busy main road but now with a right-turn onto it only fifty yards from a blind bend.
Most recently, it failed me on rural roads due to road-works closing the road. I continued to the next village with a name-board then used the proper map to continue far enough from the detour for the sat-nag not to try to send me back to the obstruction.
….
One can still go wrong with proper maps though, as when a short-cut through a lane in South Wales, brought us to the brink of a very deep cutting carrying the Heads of the Valleys road we had wanted. The OS map had been published some years previously to the road being considerably modified.
….
There is a further, deeper problem with all these electronic aids, in that they might not tell you where you are; only how to proceed from there. When I had to use it on a major, late-night detour from an A-road route I knew well, it sent me along miles of very obscure rural roads. Had I broken down I would have been unable to call for assistance because I knew only I was on a minor road somewhere between Keynsham and Yeovil, on a dark, moonless night hiding any landmarks that might have helped me find my location in the road-atlas.
This apect is becoming a headache for the mountain-rescue services, all volunteers, because too many would-be hill-walkers attempt their trips with no real maps and compass – and likely no idea how to use them anyway. They try to rely on maps on ‘phones (risking no signal or a flat battery) but this is no good unless it shows you the intervening obstacles or ground conditions. This might be worsened by the TikTok types among whom it is a fashion to visit remote or difficult spots not for its own enjoyment but to collect me-too “selfies” and antisocial-media “likes”.
Also it seems many people now have a very poor sense of direction and of “instinctive” navigation by landmarks, sun direction, appreciation of geography, own memory etc., perhaps because they think they would never need such abilities.
