Buses are the most common transport of the masses.
As we near the fourth year of the monetary crisis, they are almost universally in bad condition. There are less buses on the road as the price of spare parts has caused companies to vandalize other buses in their fleet and up to half of many of the fleets may not be roadworthy. Bus passengers are often the target for robberies, street singers, and beggars - both on the buses and in the major bus terminals. Many bus drivers are notoriously dangerous as they race against each other to try and pick up passengers before the other buses plying the same route. Metro Mini has the worst reputation for poor drivers.
