Correct, they do that all the time here. They use their car horns as greeting devices. It's like my former HUD neighbors. It's midnight during the work week, they pull in the drive, and lay on the horn to get the attention of the people inside the house. Too lazy to get out of the car and knock on the door, too lazy to call them on the phone, just wake up the neighborhood with your MFn car horn because you don't have a job and could care less about others that do and have to wake up early in the morning.
