Problem of the car horn

I watched the news. The title is “penalty, if you blow the car horn in Shanghai.” The violator must forfeit 200 yuan. It is about 3,200 yen. But, many violators drive their car in Shanghai. One fine is not so much. But, if men violate many times, the fine is not so cheap. I have been to Shanghai. First of all, I was surprised by many car horns. In my memory, people blew the horn one time per five minutes!. So, this attempt is so difficult.
