I photoed this yesterday afternoon, embedded in the pavement in the top bit of Horseferry Road, just past the Channel 4 building as I walked towards St James Park tube.
I was baffled, and despite visiting the website alluded to, I still am baffled. It says: What is Legible London? Those were my exact sentiments, and they remain my sentiments.
It is something to do with the fact that walking is often quicker, for short journeys, than using the underground. But why this plaque in the pavement? Is there some kind of electronic gizmo underneath, with feeds into iPhones or something?
I am sure there is a semi-rational explanation, but can anyone oblige?
(The fact that two of the screws are missing doesn’t bode well, does it?)
