From a conversation with Lord Mayor Newman and from the levels of debt that he is prepared to commit to major road and tunnel-building projects we have formed the view that insufficient attention is being paid to what leading experts are warning about peak energy supplies globally.

We are incurring huge debts for road and tunnel infrastructure at a time when we should be planning urgently for the emerging supply crisis globally in oil supplies.

Roads and tunnels won’t be needed except as luxury bike paths and mushroom farming sites if petrol supplies dry up. But the debt will be there to haunt us.
