Auto rickshaws (locally called "baby taxis" or "CNGs") are one of the most popular modes of transport in Bangladesh. They are best suited to narrow, crowded streets, and are thus the principal means of covering longer distances within urban areas. In Dhaka they should run on a meter system but due to price hike in their rent from the owners, the Baby taxi drivers are charging extra from the passengers. They ask exorbitant prices and you have to negotiate the price. Usually when you are in a hurry you end up paying extra with a bitter experience. Sadly the authorities are least bothered. I try to avid them now and look for other options of transport.
