I&#x27;ve long considered London to be nothing more than a giant PR exercise.  Of course the prime minister is an ex-PR guy, so a connection wouldn&#x27;t be surprising.  I&#x27;m not sure it delivers on the image it projects in any respect.  Except the new trains that have started on some lines - nice to have room to breathe when you&#x27;re stuck on a track waiting for a signal failure.  Even the new double decker busses with the aero fronts.  What&#x27;s the real difference?  Nothing.  In fact the new appearance doesn&#x27;t even last beyond the front of the bus which is what people see when it approaches - the rear of the busses is unchanged.  So we don&#x27;t have impressive new busses, we have busses that look, upon first glance, from a specific angle, as though they are.  Everything is careful illusion.  People buy into perception.  Look!  We have silicon roundabout!  Seriously?
