Just look around the world; they are the norm: East Asia (Japan, South Korea, China - Taiwan, Hong Kong, June 4 on the mainland); North America; South America, almost all of the region; Europe; Australia, NZ, Indonesia, the Phillipines; South Asia (India, and I think they are enshrined if not enforced in Pakistan and some others).

What's mostly missing is the Middle East, Central Asia, parts of SE Asia, and large parts of Africa - though there are Benin, Botswana, Kenya, and many others iirc.
