The authorities in ShanXi province, China, have had enough of people speeding so they decided to build the ultimate "speed bump":

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.

Mission accomplished! Link
