It's the Highways Agency. But actually I find minutes to next junction extremely useful because it tells me what sort of progress I can expect to make if I stay on the motorway. 'Keep left unless overtaking' and ‘Don’t hog the centre lane’ are also very necessary as it helps get members of CLOG out of the way. 'Drug Driving Costs Lives' is part of the current COI campaign to educate kids that the cops can tell when they're on the stuff so they won't get away with it. But 'Don't Drink and Drive' first thing in the morning is both annoying and worse than useless. Who necks a flask of whiskey before they set off to work for heaven's sake? And if you're still over the limit from the night before, what can you do about it once you're already on the motorway?
