In a western country we are used to hearing the horn as an outburst of anger or road rage, a scream that means: ???Get out of my way!,??? or ???Hurry up!??? This is not as true in many countries, especially in Southeast Asia, Latin America and Africa where a horn can simply be a taxi asking if you want a lift, or a car letting you know they are about to pass, or even just a simple, ???I???m here,?
