In many countries, there are particular roads that have an unusually high rate of car accidents, for example roads with sharp bends. People think these are 'dangerous' roads and call for them to be rebuilt. However, the reason why these roads have high rates of traffic accidents is not because they are dangerous but because people drive on them in an inappropriate way, for example by driving too quickly at sharp bends. If standards of driving improved then the accident rate would fall to average levels for roads generally and there would be no need for expensive road improvements.
