Drinkers in Korea Dial for Designated Drivers

via New York Times:

Korean replacement drivers - they drive drunks home in the drunk's own car.

Their work has become such an essential part of life in Seoul and other major cities of South Korea that the national statistical office last year began monitoring the price of replacement driver services as an element in calculating the benchmark consumer price index. An estimated 100,000 replacement drivers handle 700,000 customers a day across the country, the number increasing by 30 percent on Fridays, according to the Korea Service Driver Society, a lobby for replacement drivers.

Easily translatable to other countries. India already has something like this.
