The price of oil, and with it, the cost of petrol at the pumps, is all over the place. In the space of a few months, the price of crude oil has gone from nearly $150 a barrel to below $40, and now it's heading north again. Petrol prices on the forecourt have been similarly volatile. If we have already passed peak oil, or soon will, in the long term, the price of oil can only go in one direction: up. What can you do about it? You can downsize your car (gas guzzling 4x4s are so last year). You can drive more carefully. You can drive less. You can hunt around for cheaper petrol. Or you could say, 

"Because I do not own a car, I really am not bovvered."

Why not let other people do the worrying? Give Up Your Car. And get on with your life.
