It appears that the guy videotaping the cab driver is a tourist or maybe a buddy of his that wants everyone to see how much this guy sounds like Michael Jackson.
He’s driving his taxi cab while singing just like the King of Pop. This guy is effortless in his delivery of “Billie Jean” as he drives down the street. He even covers his mouth like Mike from time to time.
