Following the implementation of 20mph limits in Edinburgh, for example, the number of collisions in one year fell by 40 per cent. In the study, drivers were sorted into categories of support for 20mph speed limits based on their answers to a series of questions. This tended to be reflected by how they set their own speed limits according to conditions. The truth is that most people are not opposed to 20mph speed limits, but a sizeable minority are. Default 20mph speed limits are a good start but they must be accompanied by driver education programmes and police enforcement to be effective.
