“Speed-limiting devices should be fitted to cars on a voluntary basis to help save lives and cut carbon emissions, according to a new report. The government’s transport advisers claim the technology would cut road accidents with injuries by 29%. The device automatically slows a car down to within the limit for the road on which it is being driven. Ministers are planning to help councils draw up digital maps with details of the legal speed on every road. The system uses satellite positioning to check its location and when the speed exceeds the limit, power is reduced and the brakes are applied if necessary.” (12/30/08)
