Below is a reading passage in my English exercise book:
Oxford is most definitely prettier. It is located in the central England. It has a population of about 90,000, of which a large number work in or for the university. This is obviously what the city is famous for but in terms of getting to know the country, what is really of interest is the British Leyland car factory at Cowley. This is huge, employing about 20,000 people, yet, because of the university, it is usually forgotten. Spend a day looking round the works, seeing how they make the cars. Fascinating. Or stroll up the Cowley Road and watch the world walk with you.
I don't really understand the meaning of the phrase "watch the world walk with you". How can the world walk with somebody?
Could you kindly explain the meaning of this expression?
