For the people who don't believe this, spend some time watching urban traffic in a place like Oaxaca. 4 is a bit of a stretch unless it's a couple of small kids (that happens) and the moto is not really a moped, but not much more powerful. There's occasional bulky cargo. I am also reminded of the multiple times we were riding in a bus in Cairo Egypt and passed a donkey cart in the left lane of a 6 lane-ish "free"way.

One of the first things I thought when I first saw this thing is, oh, there will be mods.
