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....
