People driving the speed limit in the left lane on interstates
They text while driving beside other cars so everyone behind them can't pass, you tailgate them, flash your lights rapidly, honk your horn yet they are in their own little world not realizing they are in the "Passing Lane", very few states enforce the passing lane laws, yet cite someone going up the emergency lane to get around this bullshit that they ignore because they can. Then the people get upset when you flash them the international symbol of love when passing them on the right side.
Don't get me started!
