Have you ever followed road directions only to arrive at a junction or roundabout and be left guessing? After taking a wrong exit, you might spot a miniature sign in the middle-distance at the exit you wanted. Traffic authorities spend fortunes on instructional signage – but where are the directional signs when we need them!? Heathrow Terminal 4 is a case in point. At the last roundabout, you want the third exit, but the little sign is posted not at the roundabout where you need it, but at the third exit, whis is fatuous. The official mindset is geared to coercion at the expense of information – a gross misapplication of resources.
