In La Paz (Bolivia), the city hires young men and women who dress-up as Zebras and try to force cars and busses to respect traffic lights (which they normally don't respect). Zebras jump in front of busses as soon as the lights go red, forcing them to stop. They also try to teach pedestrians that they should wait until the light is red for the cars before crossing. To be a traffic Zebra in Bolivia is probably the most dangerous job on earth.
Now I understand why pedestrian crossings are called "zebra crossings"!

Local buses are often old GMC or Dodge school buses painted in bright colors and decorated with nice Chrome Hood Ornament like this one.
