Actually the horn of your vehicle is to tell people look I am here. Despite how many people use it, it is not a device to use for a complaint. Inuring people to the sound of a horn by using it to complain makes everyone less safe.

I spent just over 2 years of Army life in Panama where the drivers there have one hand on the steering wheel and the other on the horn.......LOL!
