Take a long term view of this and what we are seeing is only the start.
We are at the point of peak oil - world oil production is going to fall from about now. Just as lots of countries (China, India)want a heck of a lot more of the stuff. And just as our own North Sea reserves are running out. Basic law of demand and supply means that the price of oil will go inexorably upwards. Ever upwards.
No doubt there is some profiteering going on at the moment and there is likely to be social unrest. But nothing compared to what is to come.
We now find ourselves in a situation where the main substitute for petrol seems to be biofuel. Biofuel crops = less food crops = higher food prices = world starvation. What a choice.
We'd better get used to a no (or at best high priced) petrol economy. 'Cos it isn't going to get any better.
Question. If you were in HM Government and about 30% of all your annual tax reveues related in some way to the motor car, what would you do when you realise that oil is running out. (Apart from take a lot of expensive holidays while you still can).
Me, I'm thinking about investing in a horse.
