Derek Bateman is not a source of fact
Well, no media is entirely factual nor 'impartial/objective'. BBC purports to be both, but the reality is rather different. Editorial or individual reporters' bias clouds many articles and programmes. There is supposed to be 'balance' in political reporting, but there are many ways to do this and not all of them work.
Take all media with a large bucket of salt thrown over shoulder for luck, including this forum: an unrepresentative membership of Edinburgh/central belt cyclists and (allegedly according to comments elsewhere on the internut) a haven for oddballs and weirdoes.
