no offence taken. i am a penangite but i do not drive like them. infact, i always try to hi beam them hoggers 1st, and overtaking from the left as my last option. being an experianced driver, we always check our left mirror for motorcyclist before changing lane. (even checking blindspots, because penangite motorcylist have a tendency to hide there)

sad to say but inexperianced driver will get agitated and then switch without looking. that's also very dangerous.

note: that's why i said, lane hoggers played a part in accidents like this. others might be wrong for driving recklessly, but if you are hogging the lane with your 81km/h that makes you plain brainless. to me, brainless is just as fatal as reckless. reckless drivers might be wrong for not doing/thinking right, but being brainless you are infact not thinking at all.

I agree with those who says if there is a faster car in the right lane behind you, you should GIVE WAY.

But, I also can empathise with you on this, cause some cars are really fast, and before you can finish overtaking, they are right behind you already. Therefore, I always slowdown and will not cucuk the car infront of me (although sometimes they are obviously lacking in power to overtake  try as they might ). BUtpls.. if your car no power, and it's going uphill or whatever, dont lah slowly overtake and take 5 minutes to do it.... 

em.. why don't you post the speedlimit as well?
