Well, no matter how fast we drive, there are many other car which is even faster. So, stick to the left or middle lane. Unless we're overtaking a slower car.
The problem is, I have seen a lot of inconsiderate road hogger driving 100km/h at the fast lane while middle and left lane has less car too. I saw oncoming car flashing or signal at them but no response. Some other car resolute to overtake from the left without signal which is quite risky. Driving at legal speed limit does not entitled them to hog the fast lane as fast lane is only for overtaking.
I never really bother about other car top speed as I just signal to the left after overtaking a slower car and let them fly by. But I do catch my adrenaline rush by driving fast on empty corners during midnight touge.
Driving in relax mode put your mind in peace as you don't have to fight for space. Plan or adjust the traveling time accordingly. Stay cool on the road.
Btw, here in Malaysia, I think the sign "IKUT KIRI JIKA TIDAK MEMOTONG" only apply to maintenance workers as they usually walk on the left side when they're not cutting the grass trees while the lane hoggers keep right all the time
