Yes I was going to mention that also. It is common in other parts of the world to travel in such ways. So common it's part of normal daily life. Dangerous maybe but I am not sure we living the cushy American life should be criticizing it.
As for the idiot doing the wheelie, well hang em high.
There is a guy around here, obviously a new rider who wears flipflops, shorts and no shirt. He drags his feet for 20-30ft when taking off and looks so shaky and tense I'm not sure he is enjoying himself.
