Use the horn sparingly!!!

Honking at someone because they are doing something you do not agree with is not only a mistake it is aggressive behavior. Only use to horn to alert drivers, or to avoid accidents. Don't use it to impress chics, or say hey to buddies. The horn is a loud offensive tool only used in extreme situations!
