2. Sichuan – Tibet Highway in China
Sichuan Tibet Highway is one of the longest roads in China with 1330 miles in length. So, if you decide to take the trip, it will last approximately 15 days without hurry. The road is not paved, there are often car jams stretching for miles, and the biggest danger is in the hostilities among bored drivers. There are constant fights, theft, harassment, and even kidnappings for money when drivers are stuck in the mud for weeks.
