The Royal Automobile Club Foundation have questioned government proposals to raise the maximum motorway speeding fine to £10,000.
Professor Stephen Glaister, director of the RAC Foundation, said: "This seems such a wholesale change to the system so you have to ask what was going so badly wrong before?
"Ironically we know that speeding offences have declined over recent years and just last week the Department for Transport confirmed that even after taking congestion out of the equation recorded traffic speeds have been dropping for a decade on most types of roads.”
