If you love American cars and Russian Ladas from the 1950s, you're in for a treat! These are shared taxis, meaning they stop to pick up/drop off people as often as necessary to keep full. To hail one, simply stand on the side of a major road or intersection, raise your hand, and hold your fingers up to show the number of people in your group. To get off, point and say, aqui, which means, here. Fair (fare) warning; prices are fixed until the tunnel. Once you go thru, the price doubles. It's a distance thing.
