Motoboys

So in Sau Paulo Brazil they have so much traffic that do get anything delivered in a resonalble amount of time you have to employ a Motoboy. Crazy guys who zip though (and over) the traffic jams on motorcyles. It's very dangerous, it is estimated that 2 motoboys die everyday. Back in the day, I would have called this very cyberpunk, but that now means "computer hacker" instead of "weirdly futuristic." Gibson has bike messengers in Virtual Light that are the Motoboys, as are Neal Stephenson's Skateboarders in Snow Crash.
