Chapa. Chapas are the mode of transportation here. They are vans with four rows of seat (not including the front seat). Each row seats four people across, plus two people in the front seat, plus the driver, plus the "cobrador" (the conductor/guy in charge) who stands if the chapa is at capacity. Chapas won't leave until they are full and it is generally best to not look at the road during the trip. Imagine squeezing 20 people into your van at home.
