Navigation Systems seriously undermine road safety

Using a new research method, the Stichting Onderzoek Navigatiesystemen ("Navigation Systems Research Foundation") has discovered why navigation systems cannot find ring roads in cities. Software errors are the cause. The Foundation predicts a catastrophic development if the authorities do not intervene: more traffic accidents and casualties, and side roads becoming jammed with volumes of traffic for which they were not designed.
Almost none of the navigation systems tested take sufficient account of the hierarchy in the road network. As a result, motorists are unnecessarily being turned into 'kid killers' by being sent through designated low-traffic residential areas and roads which are not designed for through-traffic. The navigation systems do not appear to be able to find ring roads.
