Another off topic comment. On Tuesday 30th May, BBC2 at 11:20 PM is showing a program called If the Oil Runs Out. Don't know if anyone has bought this up on another thread.

According to the Times ('The Knowledge'):
2016, Saudi states that the west cannot take its oil for granted, Oil goes to $160/bbl, winter fuel costs rise by 40%, Petrol stations run dry, budget airlines collapse, shortages, hoarding, more shortages, layoffs etc.

Shame its not on at nine on Beeb 1.
