Prosecution of speed trap flasher really grinds our gears

The public highway is not normally the place to foster your love of a fellow human being (it's usually the place we grunt, grind and gesture at each other) but there are few moments in life as heart-warming as a complete stranger taking the time to warn you of a speed trap round the next bend.

It is a fleeting glimpse of driver camaraderie; a split-second confirmation that despite appearances we are, in fact, not alone on the road, but rather a full-time member of a British motoring community still capable of showing others care and consideration.
