Gorilla crossing road

A Brit in the US writes intelligently on how visual clutter and strictly enforced road signs cause the average US driver to have more accidents. It's not just road signs that the US seem to be addicted to. What about all that rubbish sitting on your computer 'desktop'. What is it doing there? How many accidents are being caused by the distractions? That's before you even step inside the Internet. Now that we can qualify for an ECDL (or even an ICDL), shouldn't we be issued with the equivalent of the Highway Code when we buckle down to work in our wired cubicles?
