The World Health Organisation (WHO), in its Global Status Report on Road Safety, 2009, predicts that deaths in road traffic will increase from 1.2 million per year (the ninth biggest cause) now to 2.4 million per year (the fifth biggest cause) in 2030. In 2007, road accidents cost the UK’s National Health Service £470m a year and the UK economy £8bn a year; all money that could have been better spent.
