Question

外语翻译，就说一下这篇短文的最后一句如何理解

The worst tourist in the world is Nicholas Scotti of San Francisco . Once he flew from the US to his home town in Italy to see someone at home. The plane made a one-hour stop to get oil at Kennedy Airport of New York. As he thought he had arrived home, Mr Scotti got off the plane. He thought he was in Rome .
When nobody was there to meet him, Mr Scotti thought maybe they were held up by heavy traffic. While looking for their addresses, Mr Scotti found that the old "Rome" had changed a lot. Many old buildings were replaced by high modern ones.
He also found that many people spoke English instead of Italian and that many street signs were written in English.
Mr Scotti knew very little English, so he asked a policeman(in Italian) the way to the bus station. He happened to meet a policeman who was also born in Italy and answered him in the same language.
After twelve hours' traveling round on a bus, the driver handed him over to a second policeman. He asked the policeman why the Rome police employed so many people as policemen speaking English of Italian.
To get him on a plane back to San Francisco, He was sent to the airport in a police car with sirens(警报) on. "Look," said Scotti to his interpreter , "I know I'm in Italy. That's how they drive."
