Agree with you entirely, the figures do back you up tremendously. It is deffinately not the case on Weston road in Lichfield though I can assure you. I haven't any exact figures on this stretch of urban road but I would bet with you my mortage that more accidents have occured since the introdution of the traffic calming methods, try and get the records off Staffordshire Police, they will back me up. I have lived near this road for over 20 years and since the humps were introduced there has been numerous accidents and I personaly have had many a near miss due to drivers swerving in an attempt to dodge the said humps. These drivers are not the young "boy racer" type but the mothers on the school run and the older drivers not paying attention to what is comming the other way, beleive me I know through my own nerve shattering experiences.
I stick with the assumption that speed does not kill, yes mix speed with poor driving and your heading for disaster, poor driving is the biggest killer.
