"Another one, and the one that I faced several times today, big trucks trying to pass each other. Today I was driving on I71 between Cincinnati and Kentucky. It was mostly a 4 lane highway once I got past the 71 and 75 split. So two lanes going my direction and a lot of hills. Much of that time was spent behind a big truck who felt that he HAD to pass the big truck in front of him on the long hill. He pulls out to pass in spite of the fact that he is only able to muster a speed of about 1 MPH more than the truck that he is passing. So 10 minutes later he FINALLY manages to pass the other truck and get back into the right hand lane. If you don't have the power to get around the truck in front of you, STAY BEHIND it. Don't be an inconsiderate ass and back up everybody else."
While I agree this is irritating, the real problem here is non-uniform engine governance and mileage-based pay. I drove OTR for a couple years, and the pay by mile almost forces this situation. If the passer just stays behind the passed, he loses money.
