> You cannot hear some crazyman running at you, screaming, until he has passed you? You cannot hear the stereo in some guy's car until after he passed you? You cannot hear a siren of police until the car has passed you?

For all of those things, you will see them pass you before you hear the sound they emitted when they were passing you. (Maybe not by enough to be noticeable, given the smaller distances involved)
