In a three lane situation in America, generally the outside lane is for trucks and slower traffic, the middle lane is for cruising, and the inside lane is the passing lane you describe. It is unreasonable to expect a car driving the speed limit in the middle lane to move into the truck lane because someone doesn’t want to use the passing lane to pass slower traffic, which is its purpose. In the picture, moving to the right wouldn’t leave a lot of distance for the car that the car in the middle lane just drove past even if that were the right thing to do.
And none of that empowers anyone to create an unsafe situation for other drivers on the road.







If you leave two seconds of following distance, someone will cut it in half. Some asshole in a lifted pickup will pass you on the right and flip you off, no doubt screaming something about left lane campers. I can’t literally drive through the car in front of me. I want to go fast too but there’s a left lane camper there. 🤷
