On my way to the airport, a few final interesting transportation observations about Brazil which you are likely to be familiar with if you have been here.
Video One: A significant number number of trucks have the ability to lift some of their wheels off the ground when not fully loaded (to save on fuel). You don't tend to see this to the same extent in other countries.
Video Two: Motorcycles quite commonly create their own unmarked lane between car lanes in which to speed by in convoys. Cars have to be very careful about changing lanes.
