the main thing is to remain calm and collected. dont get emotions into the picture, if u do then they have already won half the battle ,

usually depends la,
1) if highway and i overtaking somebody usually i will move a bit faster if the guy behind is being a gentleman and using his signal and not his high beam.
2) if he is flashing/ signaling from far away on a two lane road and its empty i will move to the left
3) if i am overtaking and he flashing... i will floor it and smoke him.
4) but the worse is if for no reason at all that guy wanna tailgate me (maybe asking for a road race) just ignore until he overtakes. and then see his next step, if he brakes then maybe if i am alone and the raod is clear then i will persue, but if he goes his way then i will forget about it.

if i am planning to do something, i do it when i am alone in the car, i dont want to risk the lives of my loveones... hope u all do the same too

my favorite is JDM cars, haha, just floor them until they reach their 180kmph limiter, then wave bye bye. , but of couse depends on road conditions and traffic...

safety first guys
