Based on the way you say you drive... egotistically acting like a pace car in the left (#1) lane of the freeway... you probably are most of the adjectives you just listed.
Everything Occom Bill said in regards to the logic used in freeway driving, is accurate.
Everyone has their place on the road, everyone can go a speed very close to what they want. They just need to be in the proper lane.
If the cars in the lane to the right of you are faster than you, then you are in the wrong lane. Simple as that. That rule is always true, too. Except in traffic jams, where there is no natural traffic flow occurring.
But when natural traffic flow is occurring... it is damn rude to drive slower in the left lane. It's also damn rude to drive at exactly the same speed as the drivers to one's right. If you are parallelling are car that is on your right, then you need to let up on your accelleration temporarily so that you can squeeze in behind the very car you were parallelling. This way traffic that was behind you in the leftmost (#1) lane can then go the speed that it naturally is inclined to go.
People who drive slower in the left lane have fragile egos. They're afraid of being walked on, and they lack so much power in life, that they relish the fact that they are driving the posted limit, and get some sort of satisfaction that they are slowing everyone down behind them to make them comply with the posted law. (These types of weak people also tend to disregard the laws that address the left lane being a passing, or faster lane).
But beyond the law, they are just socially sad people. Desperately clinging to some authoritarian worldview, applying that to traffic logic.
Every driver has his place on the road. He just needs to be in the proper lane. It's not hard to figure out, unless one has a fragile ego.
