Mr Cameron's Big Society proceeds apace in Aberdeen "City and Shire". It's great that this spirit of self-empowerment has spread to the hard-pressed drivers of Aberdeen Cars - why should they allow petty officialdom's stupid rules like "red light means stop" stand in their way? They're Busy! They're Important! The Big Society says they can do as they please, dependent upon how important they deem themselves to be. And in this town, the drivers rightly deem themselves to be very important indeed!
In any case, they're definately more important than some automatic petty traffic control robot (the traffic lights.) Gotta get home in time for the Simpsons!
