a typical stupid malaysian mentality

u tailgating me, u see brake light, hahahaha.
your subconscious mind is to break when see brake light, if brake hard at high speed, you die. simple.

Don't realize yes, but what if you have some ass clown hi-beaming even way before coming up your tail....? I know becoz I'm aware he's coming up behind me when I was about to give way... sometimes it's this kinda ppl who thinks they own the road that makes me wanna hit the brakes instead of giving way...

There's a f***ing polite way to let ppl know you wanna pass - right signaling...

Better don't simply hi beam the car in front of u. Silap haribulan You kena chase all the way by the car you hi beamed who happen to be gangster, off duty policeman, royalty members. sick psycho, driver high on drug or alcohol etc etc and got beaten up. Already so many reported road bully cases in newspaper where the root cause of the bully started off with flashing of hi beams.
Personally, I find hi beam from behind is rude and can be very provocative to even decent driver like TS and I normally wait for the clearance to overtake from the middle lane.
