When there is a speed limit and I'm doing it, I'll be doing it in the left lane or a center lane, whichever is smoother and clearest of cars traveling sub-limit. Your speed, when in excess of the speed limit, is of no consequence to me, unless you are an aid vehicle. Tailgate and flash your brights all you like, I'm not getting over. That's your obligation, as the one seeking to exceed the speed limit.
