Personally, I could care less, when I am running 5 MPH above the posted limit in the center lane in an area where people are entering and exiting the highway, often at speeds 10mph or more below the limit and some A******e running 20 over the limit wants me to move over. No matter how fast you drive, someone wants to go faster. I move to the right lane when I get close to my exit or I exit the congested area. My big gripe is the 18 wheelers which pull up so close to your rear bumper that you can't see anything in the mirror but the radiator, then complain on a radio talk show that it takes 5 times as much distance to stop a big rig as it does a 4 wheeler, so I guess we shouldn't be on "their highway". Personally, I think that the cops should give 1 week notice and then strictly enforce the limits. They did that once on I 81, and they caught some motorists 3 times before they left the enforcement zone.
