When I was in China, i often ride in friends' cars. The first thing I do when I get in cars is buckling up, and I'm often ridiculed for fearing of death (i really am). Twice I sit on the passenger side and tried to put the seatbelt plate into buckle but I couldn't, because there's already a key holder in there. I learned since no passenger wear seat-belt, the driver just put the key holder there to silence the warning noise, they already have key holders in on driver's side.
