Durban's public transport system is limited. The city's bus network, which services the city centre and surrounding suburbs, has fallen dramatically in quality in the last few years, resulting in an erratic schedule that may leave passengers stranded.The mode of transportation used by most working-class Durbanites is the minibus taxi (or kombi). They stop anywhere along their routes when they see people to pick up. These are cheap and widespread but often cramped, and can be dangerous as the drivers are aggressive. Minibus taxis should only be used during the day and on busy routes, and travellers should not enter an empty minibus.Durban has several reputable metered taxi companies but these can be expensive for long journeys. It is always advisable to use a branded cab. Prices can be negotiated upfront, or the meter can be used. Most cabs do not take any form of credit card and tipping is customary. Uber is another option and has become increasingly popular in South Africa.There are many places to hire cars in Durban. However, visitors should avoid driving in the central business district, as traffic during the day can be very congested and the streets are considered unsafe at night. Doors should always be locked while driving as hijacking is a serious concern in South Africa, and purses and other valuables should not be left visible on seats. Renting a car is the ideal option if travellers are planning excursions out of the city.
