I’ve described driving in Panamá as a harrowing experience, although it has become marginally less so with practice and development of my mad truck-driving skills. As I’ve driven it has become apparent that the drivers, though aggressive, are generally at least conscious of what’s going on. With one glaring exception: Buses. Down here, the rules of right-of-way are simple. Bigger things go first. And buses are bigger than everything. If you’re in a small car, good luck. If you’re on a bike or walking, god help you.
Panama City has two bus systems. The first is the official public transit system. Initiated in 2010, the Metrobus System is part of Panamá’s push for modernization. The buses cost 25₵, paid off a rechargeable orange-and-white card.
The second system is older and less of a “system” than a coincidence of independently owned and simultaneously operated buses. The buses, for the most part retired American school buses, are vividly and imaginatively decorated according to the owner’s and artist’s tastes. Called Diablos Rojos (red devils), the buses are run by a two person team of driver and conductor. The driver will stop at official bus stops as well as any promising-looking corner or cluster of people, and the conductor will jump from his perch just inside the doors, often before the bus has fully stopped, energetically calling the destination. To get off the bus, one stands and shouts “aquí” (here) or “pare” (stop), or loudly slams the ceiling of the bus.

Diablos Rojos: flashily colored; garishly lit by night; and festooned with the faces of celebrities, Jesus, or the owner’s own children on the rear door.
Strictly speaking, the older buses are no longer legal. Partially to cut back on competition when the official system was instituted, and partially because the Diablos are old buses and heavily polluting, the government paid buses to stay off the road. The initiative was largely unsuccessful and there are still at least as many Diablos Rojos as Metrobuses on the roads.
Unfortunately, the attempt to institute a uniform public transit system leaves much to be desired. While the new system is supposedly more attractive to outsiders, with its shiny new Mercedes-Benz buses and swipe card system, its streamlined face feels like a façade covering its shortcomings. The system fails to account for the number of people who use the buses and for the times of highest demand. The routes in the new system don’t go as far or come as frequently, leaving gaps in service of sometimes considerable length. There is no bus schedule, so drivers arrive and depart more or less as they please. The drivers themselves are often the very same ones paid by the government to leave their old buses behind, then rehired to drive the new ones.
This is not to say that the system doesn’t work. The gaps in the Metrobus service are readily filled by the old system, which still thrives despite government attempts to phase it out. And while I wouldn’t say it is the most efficient or effective system, it works.
