personally i think if u are the at extreme right lane, no matter
how fast u are, be it 100km/h, 150 or 200km/h. if there is a car
behind u, and they are faster than what u are travellin at, u
should give way. thats what i personally feel.
doesnt matter if the freeway is 90km/h or 110km/h or what.
and also try to keep to the middle lane if possible.
i have seen taxi drivers, hoggin the extreme right lane at 100km/h.
yup u can say he is speedin, but if u look at the back of his taxi,
ther are like 4-6 cars all so much faster, but yet they are still
stuck behind.

dun road hog. thats the best.
