I think it was one of Douglas Adams's later stories that included a cabbie who never had a passenger say, "Follow that cab!" So, the cabbie came to the conclusion he must be the cab everyone else is following.
Drove a cab for 6 years and never had that happen. Mostly it was people who wanted to smoke when it was against the law and wanted to anyway because they were paying for the ride.
