The Ultimate Speed Bump

The local government in ShanXi province, China, decided they had enough of people speeding on their highways.
In an effort to stop speeders once and for all, they built a 100 foot long and 2 foot high winding speed block in the middle of the Jing Zhuang highway.
Unfortunately for the drivers, the speed bump is so narrow that a large number of cars end up scraping against the side even when driving careful. The speed bump has also taken the 2 lane highway down to a single lane, which has resulted in daily traffic jams.
