A taxi in Shangri-La, that's what. These little oddball cars were all over Shangri-La, though I didn't see them anywhere else. It's pretty funny to watch them do a U-turn. Apparently they're not street-legal in Kunming (nor, I would assume, other moderate-to-large cities), but things in Shangri-La are evidently a bit more lax. I was told they're frequently used as taxis up here.
This isn't the only make and model; there are a number of different ones (a little Googling shows that there is a knockoff 3-wheeled Prius, among others). And they do come in other colors, too.
