Sat-navs are robbing us of our sense of direction: Expert warns we risk losing our navigation skills if we keep relying on GPS

Earlier this year a US tourist in Iceland drove 226 miles (364km) too far because he was following his sat nav. While tourists in Wales looking for the beautiful falls in Neath Valley often end up in a nearby cul-de-sac because the two locations share the same postcode. Although these stories are amusing, for everyone apart from those involved, they represent a worrying trend of people'over-relying' on GPS. Now an expert warns that it is not only making us lazy, this dependence could rob us of our innate navigation skills. Our increasing reliance on satellite navigation is coming at a cost and is harming our own ability to navigate, says satellite communication and navigation consultant Roger McKinlay.
