A device that automatically slows cars to the local speed limit would cut the number of road accidents with injuries by almost 30%, a report has claimed.
Transport advisors to the Government say voluntary speed-limiting devices would also help towards protecting the environment by reducing carbon emissions.
The system uses satellite technology to ascertain the position of a vehicle and check the local speed limit. If the vehicle is moving in excess of the limit, power is reduced and the brakes are applied, according to the BBC.
The Government is planning to work with councils in drawing up digital maps with details of the legal speed on every road.
On the evidence of trials, Government advisors the Commission for Integrated Transport and the Motorists' Forum are calling on ministers to introduce of the system, which they say would cut motoring injuries by 29% .
But motoring groups are expected to reject the move, concerned over a loss of control for drivers and suggesting the importance of speed in causing accidents may have been overestimated.
