No Honking In Traffic!
If you are from Chicago, New York City, or any other metropolitan US city, you are likely experiencing culture shock at the moment. These cities get littered with noise pollution, namely in the form of honking and other noises that cars produce. In traffic jams and other traffic situations, the horn sees its fair share of use.
No such thing is true in Japan, however. It is not allowed to honk in traffic in the country. In Middle Eastern countries, honking is quite prevalent, so it must be odd when people from Japan visit these countries. Do you think it is quieter in Japan as a result of its no honking policy?
