Indonesia is the world's most populous Muslim country but, until recently, it was home to a liberal form of Islam that suited the Indonesians' laid-back, easy-going lifestyle and flourished under one of South-East Asia's most successful democratic governments.
Like most South-East Asian countries, it's also home to hundreds of thousands of mopeds and light motorcycles, which are used to move anything from kitchen units to entire families.
In 2001, however, the more militant northern province of Aceh asked for, and was granted, an increased measure of autonomy. Since then the provincial government has begun instituting sharia law, including the stoning of adulterers, flogging homosexuals and a ban on women wearing tight trousers.
Now the local government of Lhokseumawe, at the northern tip of the island of Sumatra, has passed a regulation prohibiting women pillions on motorcycles from sitting astride behind a male rider, describing the position as "improper".
Mayor Suaidi Yahya said that under the new law, women would have to sit 'side-saddle' with their legs dangling off to one side.
