“If see a potential slow driver wanting to get into my lane which is moving, I do not slow up to let them change into my lane.”

CB, common courtesy should still be exercised on the roadways. If an elderly person showed up at the cash register at the grocery about the same time as you do you rush to get in front of them?

You sound like a bad driver, please be more careful. Remember, those are actual people on the roads around you not just obstacles.
