I didn't want to make for each and every question about Vietnam a thread of their own, otherwise Draven will scold me.

So this thread is for questions about that is not related to Vietnamese language, but have a more general nature. I hope a thread like that doesn't exist already.
#1: I want to know whether bicycles still dominate Vietnamese streets like they used to do. If not what vehicles is most seen on Vietnamese streets? Thanks in advance.
#2: People in Vietnam often say how hard they have and always saying "Ối giời ơi". The epitome of this is "Cải Lương". Do Vietnamese have the habit of .... well.... complaining or whining? Or do they like drama? :/
