A consultation will be announced immediately by ministers on a series of vehicle safety measures that will trigger an alarm or reduce engine power if drivers exceed a certain speed limit, the Daily Telegraph reported. The technology, known as “smart speed assistance”, relies on GPS tracking and vehicle cameras and was previously described as a “big leap forward” in road safety by EU officials. Tory MP Craig Mackinlay, chairman of the Fair Fuel UK Motorists and Hauliers pan-party parliamentary group, said the proposals sound “very conservative”. He said: “This will completely destroy the luxury car market and I think there are so many aspects of the anti-driver campaign now coming to the fore. “This is more Big Brother in your cockpit. We will see more of them if we go up the road pricing route. I do not think people have thought about the aspects of freedom of all these. It just sounds very conservative. “ The choice of warning given to drivers violating the speed limit will depend on the vehicle manufacturer and may range from reducing engine power or depressing the pedal backwards. Drivers could bypass the technology, but it would reset after each time a driver restarts the vehicle. Some manufacturers such as Ford and Citroen have already started using speed limitation technology in their vehicles. Edmund King, president of AA, said speed limits on the roads should be very precise in the digital system to ensure there are no problems. He said: “Speed ​​limits must be absolutely accurate because the car reacts to the speed limit. “If you have the wrong speed limit on the digital system, it can slow you down to the wrong speed or allow you to accelerate to the wrong speed.” The Department for Transport (DfT) has said no decisions have been made on safety regulations to be followed by the UK. A spokesman added: “The UK’s withdrawal from the EU provides us with the platform to take advantage of our regulatory freedoms. “We are currently reviewing the vehicle safety provisions contained in the EU General Safety Regulation and will apply requirements that are appropriate for the UK and improve road safety.”
