Very seldom that semis run at their speed limit, now days the limits are 65 autos, 60 trucks most semis run between 65 and 70, autos 65 and 75.
Running 20 mph below the flow of traffic in the right lane, basically setup a rolling road block.

Rolling roadblock? That's what that passing lane is for. If people would drive like they should, i.e. move over to pass and then move back over to their original lane, it wouldn't be an issue, but instead you have people that pull into the right lane and just sit there, even when they could get back over. There's your rolling roadblock.

Makes a person wonder how they keep the autobahns in Germany from being endless car wrecks, when you have people driving 100+mph and other people doing 60-70 mph. Oh yeah, they know how to drive.

Well when you consider about 90% of the interstate system is only two lanes in each direction, a rolling road block is a vehicle going significantly slower than the general flow of traffic forcing all to move to the left lane to get around them. If the volume of traffic is higher than moderate many will have a difficult time fitting into the left lane.

The reason the Interstates were made to this expensive design is exactly that: the right-hand lane has precedence. It is the travel lane. The passing lane exists only to facilitate a legal pass so that traffic in the right lane remains at a higher average.

Extended travel in the left lane is illegal by definition. The left lane has NO right-of-way whatsoever. The exception to that is during the close confines of a pass. One cannot be in the lane otherwise.

Only the stupid argue they’re going faster. Traffic volume determines average speed. Irrelevant how fast one WANTS to go.

Next, It is illegal to otherwise block entry to the left lane. Period. A pass is by one vehicle at a time.

In a big truck I put my lane-change signal on per requirement: as I am ready to start the move to the left lane. I AM NOT, “asking permission”.

This makes the cretins mad as reading was never a required subject. Have even had a few hit me this year. No concept of what is ROW and who has it (situation).

Emergencies happen. Smooth 67-mph traffic in travel lane and no left lane illegals, a suddenly stalled vehicle — or worse — means traffic diverts around into the left lane. It means the big trucks are coming over as that Is the road design.

Right lane (of two lane) ROW is an absolute. All other rules start from there.

If you are in the left lane, you will be at fault. Assuming you live to tell about it.

As to RVs, none of you have the brakes you need to do over 60. The trailer electric drum brakes will have ceased functioning before you come to a full emergency stop.
If you are passing much of any traffic, you’re the handicapped vehicle that screws it up for everyone else when things go wrong.

58-62/mph covers a range where other traffic flows around you as you learn to manage that situation . The big trucks are at 64-66/mph and all the stupids run in packs above that.

NEVER be in any crowd, ever. Vehicles ahead, behind and athwart means you’re in the RV with the picture title of, “Can’t fix stupid” .

It isn’t hard to learn how to stay away. How to drop off 5-10/mph and get them gone. . A football field or more.

What is your FULL emergency stopping distance? Why haven’t you measured it? One-half of that (including 100’ extra for reaction time) is your dead-minimum. Where you pullout to pass. What you use to re-enter the right lane.

None of this was anything controversial 50-years ago. Everyone knew. The two-lane highways made passing difficult. Headlights & Hand Signals. CB Radio. It was coordinated. Cooperative.

Someone’s slowly passing you YOU ARE OBLIGED TO SLOW MIGHTILY TO GET THEM AROUND YOU SOONEST.

That’s the Interstate design. The way rules flow from First Principle: The health of theTravel Lane.

Stay below the flow. Manage (and help) others get past. Stay separate.
Plans stops in advance of leaving, and execute those legs one-at-a-time.
