There are ways and means of getting about that don't involve four wheels, but in this slice of vintage Clarkson, Jeremy isn't much interested in them.

Back in 1996, he took himself off to twelve countries (okay, eleven - he goes to America twice) in search of the hows, whys and wherefores of different nationalities and their relationships with cars. There were a few questions he needed answers to:

• Why, for instance, is it that Italians are more interested in looking good than looking where they are going?

• Why do Indians crash a lot?

• How can an Arab describe himself as 'not a rich man' with four of the world's most expensive cars in his drive?

• And why have the otherwise neutral Swiss declared war on the car?

From Cuba to Iceland, Australia to Vietnam, Japan to Texas, Jeremy Clarkson tells us of his adventures on and off four wheels as he seeks to discover just what it is that makes our motorworld tick over.
