When I go on cruise control at 64 in the far-left Carpool lane in a 60 MPH Zone, and people think I ought to be going 70+, well, they can just go around me in the fast lane.
If you did that in Oregon they could give you a ticket (thank God!)
The left lane if for passing, once you’ve passed, get over to the right lane.
To sit there going slower than the flow of traffic is selfish, and dangerous, causing dozens of cars to have to go around you.
