I must agree with the others that this kind of driving is very dangerous. My reason for not doing it is that it pisses the other person off. And many times, a normally calm person will do outrageous things because of a little anger or road rage. I used to do the same thing and saw people try to pass in no passing zones, residential sections, and almost cause accidents to on coming traffic by passing unsafely. I would feel absolutely horrible if I caused a person to pass unsafely and made oncoming traffic swerve and get into an accident. And even worse if someone got hurt or worse....
Life is too short to worry about people passing you. Just let it go.....
