Allow drivers to go 'flat out', says new police chief He added:"While speed may be a factor in many accidents I believe it is inappropriate speed that is the main contributory factor. That is why I call on drivers to consider the road conditions and drive accordingly. We need a common sense approach to simplify regulations and limits for drivers and reduces the need for all these changes of speed limits. I agree with those who believe we should revisit the current upper speed limit of 70mph on our motorways and modern roads which have been built, along with vehicles, with safety in mind This may be unpopular is some quarters and research would point to whether this could be universally acceptable - my comments were designed to provoke the debate. But a spokesman for the Guild of Experienced Motorists has described Mr Bett's comments as "just nonsense." The organisation's David Williams said:"One in four road deaths is caused by inappropriate speed. It is a very important issue and it needs to be enforced because we need to protect innocent road users from people who think they can drive like racing drivers on the highway. And David Quarmby, chairman of the RAC Foundation, said:"Speed limits are set to reflect the inherent risks of different types of road - risks to drivers and other road users such as pedestrians and cyclists. While Stephen Bett may be mesmerised by varying speed limits, there is no evidence to suggest the average driver is. The observance of speed limits has improved significantly over the last decade, and as a result the number of people killed and seriously injured on our roads has fallen nearly 40 per cent in the last decade alone. And the PCC for neighbouring Suffolk Tim Passmore said he did not agree with Mr Betts' speeding suggestions. He said:"I think we have got to be very careful about things like this." Mr Bett took became on of the country's 41 elected police and crime commissioners after beating four other candidates in last November's elections. An a political independent, he was a member of the Norfolk police authority for sixteen year, the last six as chairman.
