Pesero drivers do not receive a fixed salary but are required to meet a daily quota prescribed by the owner of the vehicle. The driver is then allowed to keep the rest of fares of the day. This fosters fierce competition among drivers, as every passenger is seen as valuable merchandise towards meeting the quota and thus increasing the driver's personal profit. As a result, often, two or three battered down peseros race furiously against one another with complete disregard for the passengers they carry or for other vehicles. Accidents, often deadly, ensue and are fairly common. However, the lack of any real alternative keep them in high demand throughout the city.
