 If you live in Jerusalem, then I'm guessing that you're very familiar with this sound. It's unnecessary honking, and it's what I like to call the background soundtrack of the city. Today is Yom Kippur when streets around Israel will be empty. And it always makes me wonder, how peaceful would it be if our roads were this quiet for the other 364 days of the year? Many people are unaware that honking a car horn for no reason is illegal and punishable with a fine. Under Israeli road law, horns are only supposed to be used for impending emergencies. The problem is simply that nobody enforces the law. Thankfully cities around the world are waking up to the damaging nature of noise pollution which has been linked to high blood pressure and cardiovascular disease. Even Petah Tifa in Israel is piloting a smart detection system that uses automatic sensors to issue nuisance honkers with fines.
