Fed up of people speeding on the highway the local authorities of ShanXi province, China, came up with an ingenious idea they built a 100 foot long and 2 foot high winding speed block in the middle of the Jing Zhuang highway. So after cruising at around 100 - 120 miles per hour on the two lane highway drivers have to squiggle their way out of the narrow bump where majority of them end up scrapping their cars. Oh and the single lane highway does cause endless and frustrating traffic jams.
