My 2 cent,
As "System Error Message" said, the road speed limit is actually designed based on road designed. Its NOT designed based on the fastest car speed limit. Mostly braking distance, reaction time on an object in distance view etc.
Yes , your car may be faster and able to handle better than others, but who knows, so whenever you are above the speed limit, you are endangering the life of yourself and everyone around you. So I wouldn't fault those following speed limit while in any lane of the road.
If you feel you hogging the road or want to overtake, just put indicator light and make the others aware and do it safely (safety is paramount for whatever reason !!), for whatever emergency there are emergency lane (impatient driver is not an emergency).
So keep calm and drive well.
