Concerned bout Motorists..almost accident

There is one day i was driving home from my work place. I was just after night shift. My eyes were half close and very tired. As usual i pass through this village call Kampung Chuah. There famous for selling fish. Fine.

So i drive as normal speed at about 60-70 km/h at the village. Then i saw this youngster motor cyclist with no helmet on. He rode on the left side as all motorist should be. Then suddenly he steer abit to RIGHT side and look behind. My car was very near him already.
Then i immediately STEER hard at right side then STEER back to left side.
ARRGHH~~~!!!

If i didn't steer right i would have hit them already for sure. How could he steer to right and see behind??

So those who ride motorbike please be more cautious. I always been very cautious bout motorbike though i sometimes don't like them.

If accident happen, sure the police would say its the CAR FAULT....

sigh....

Here is the drawing how it happen..LOL
