so why do police put blue flashing lights on ?[/QUOTE]
Because they're told to. Having said that, their behaviour is so unusual, so different to prevailing traffic flow, that it doesn't bear comparison
Much like the EU tells car manufacturers to install DRLs right across Europe, despite there being no evidence it makes any safety improvement outside of a sub arctic climate.
Like the EU nearly introduced mandatory leg protection for new motorcycles in the Eighties, despite evidence showing that in severe collisions they tore riders in half at the hip. It was only frantic efforts of the manufacturers that stopped this at the 11th hour. In fact, it was later discovered that the EU mandarin responsible for this, and other, attempts at introducing oppressive motorcycling legislation had suffered the indignity of his wife having an affair with a biker, hence his rabid efforts at ridiculous and unproven safety legislation. His personal vendetta against everything two wheeled was quietly coveted up.
Like the regulations that dictate people wear hardhats in certain perceived high risk environments, despite their being no physical means by which anything could fall upon their heads. Such as walking round a building site on day one before any work has actually begun.
We are told to do many things in the name of safety, but in surprisingly few cases is there any actual science that proves a safety benefit. The bulk is based upon perceived wisdom, which usually contains very little actual wisdom at all.
Perceived wisdom misguides, misdirects, and misinforms. Do not give it credence.
