Bus driver Oscar Gómez lives in San José Petare, Caracas. Here he puts petrol in his car. The petrol is heavily subsidised and is thought to be the cheapest in the world at 0.95 Bolivares a litre. At current exchange rates you couldn't fit one US dollar's worth of petrol in a car. A taxi driver uses around 50 US cents of petrol in a day's work, at the official and less-favourable exchange rate.
