>in addition, i am tired of mega speeders tailgating me when i am trying to pass a car. some people just feel like they own the road and there's no point arguing with them...

Right, this is my pet peeve with all this.

I do use the left lane as a passing lane, but way too often I find myself passing someone at say 72mph (they are going 65), and then someone roars up behind and is tailgating me all pissed off because they want to go 90.

Yes, it's a passing lane, but that doesn't mean people there are allowed to go 90 just because they are passing. These people probably say "he was sitting in the passing lane!" But I really wasn't intending to, it was just taking me 30 seconds to pass someone because personally I'm not interested in going 90 just to pass.
