Things are changing in London, as we've all been reminded by the authorities in the most jocular way possible. TFL have successfully managed to smuggle, through a 'humorous' ad campaign, the awful truth that no one will get anywhere at all during the Games. This is fine, if you believe the billboards with their hoards of robotic, smiling commuters happily acquiescent to the jams. Not so fine if, in reality, you're a neurotic stockbroker unable to get into Pret of a morning. The same is true of the roads which have been painted in celebration, and these murals of misery will go on to haunt us still further following the end of play as they laboriously paste over them again. Presumably ambulances will still receive priority along Games Lanes, but one assumes that they won't be readily available anyway considering the temporary surge in population and probable number of Japanese tourists calling 999 to complain that their train is late.
