In the Guardian (21 May), Vince Cable warned about the scale of economic decline and the coming squeeze. He stressed the time and pain required to rebuild our broken economic model. He predicts the impact on living standards will come not from cuts, but from world prices and a 20% devaluation in sterling. I’m no economist, and Cable is no fool, e.g. he is aware of naked streets. But is he missing the pig picture and a stunning opportunity? In traffic system reform there is vast scope for civilising streets, making roads safe, providing tens of billions of kind spending cuts, cutting the carbon footprint, providing sustainable jobs. No-one loses, except fat cat traffic salesmen, technocrats and bureaucrats. How loudly do I have to SHOUT? Is anyone out there listening!?
