The BBC’s Christian Fraser reports from the back seat of a dilapidated Fiat taxicab to describe a city of utter traffic mayhem.

Modern Cairo was built to house four million people. It has now swelled to some 17 million which is why narrow two-way streets on the banks of the River Nile, are by 0900 local time transformed into four-lane carriageways.

Drivers swerve with the greatest dexterity into the tiniest of spaces. Nearly every car or bus carries the scars of battle.

The rules are pretty simple. Full-beam headlights and blaring horns somewhere behind usually mean you are about to be overtaken - or undertaken - at high speed, even though there is no space between your car and that concrete wall beside you.

One more business opportunity, it seems, for flying cars. Proper flying cars, that is, in the Jetsons manner.
