Depends lar, on the roads, some of them are the same, regardless
of race, age and gender.
Typical mistakes i notice while on my bike, the bus or on a
car
-no signalling when turning.
-hogging two lanes.(quite rare)
-Driving as if hurrying to reincarnate, quite alot, weapon of
choice is always those "riced" up 1.6 litre sedans.
-Changing lanes multiple without notice, no signalling.(quite
rare.)
-"Hao lian their merc" experienced once only, was on my bike within
the yellow lines on a straight road when a bloody merc chionged
past and horned all the fucking way, there wasn't even any cars
nearby.... 
Couldn't help but give a finger salute.
-At a turn, while on my bike, the people would step on the
accelerator, overtake me, then brake infront of me then turn, no
patience... nowadays, when there is a turn, i ride "outside" a
little more to prevent them from doing so.
During a turn where you can turn two directions(middle lane), left
go green light on but right turn is red, i was going to turn right,
stopped at the side of the line and a bloody car tried to squeeze
even though there wasn't much space.... If i was in a car, it could
not have done this, now, i stop at the middle to prevent
squeezing.
But most are ok though, its just that a few of these rotten apples
spoil everything....
