I have written to the chairman of the National Safety Council about the danger of sleepiness and drowsiness. This cause of accidents is not properly highlighted. I confess that I once knocked over a bus stop. It was, fortunately, a bus stop and not a tree, otherwise I would probably not be here. In case anyone thinks a scandal has been uncovered, I reported the matter to the Garda the following morning. Why do accidents happen late at night? Drink is not the only cause.
