One of the things I see often is someone that was in the right lane, and changes to the left lane to pass, as I am approaching, and then takes a few miles to get past. Then, just as they clear the bumper of the slower vehicle, they speed up 10 MPH to make the pass and get over. I have to really haul buns to get around them before they pull back over to the left and slow down to match the speed of the car in the right lane.
I really prefer these type of interstates. No traffic. Just outside of Checotah, OK
