Nothing infuriates me quite so much as people needlessly beeping their horns at me when I ' m driving ( except maybe being told to shut up , be quiet or not talk about something I ' m talking about ) . It fills me with a terrible indignant rage . If I had a gun in my car I would use it freely and without guilt on people who beep their horns at me without a damn good reason . So think about that before you get all impatient and obnoxious with the horn .

What driving habit drives the narrator crazy ?
People beeping their horns .
