"PARIS, France (Reuters) -- Car-pools and driving restrictions could help shave at least a million barrels a day from industrialized nations' oil demand in the event of a supply crisis, the International Energy Agency has said. They are among measures an IEA study 'Saving Oil in a Hurry' says consuming nations must plan to ease potential shortages and price rises which could result from a large disruption to international supplies. Oil prices have already risen to record highs above $58 this year as surging demand in Asia's emerging economies pushes world supplies close to current capacity. Goldman Sachs bank has warned of a potential 'super-spike' to $100 a barrel.
