Satellite navigation; it must be one of the greatest inventions of all time, mustn't it?
The days of keeping the AA road atlas on the backseat are seemingly numbered, as these pocket-sized devices vow to get you to your destination with greater ease than ever before. They know where you are, they know where you're going, and, in certain cases, they'll even keep an eye out for traffic and speed cameras.
But it isn't all good news for the likes of TomTom and Garmin. Despite the fact that half of Britain's population is said to use satellite navigation systems, the devices are becoming synonymous with freak accidents; cars driving into rivers, vans trapped in tight country lanes and lorries wedged in narrow streets.
Vehicles on the road to nowhere are apparently becoming a common occurrence, so much so that the UK government will hold a summit in March in an attempt to tackle the issue of drivers being misdirected by out-of-date directions.
But that brings us neatly to our question of the week: has your sat-nav ever led you astray? Have you suffered from out-of-date maps? Or is common sense all that's required to make the most of GPS navigation? Whether you're a sat-nav user or you prefer a traditional map, share your thoughts on the subject in the HEXUS community forum.
