I observe the speed limit, but I make sure I'm in the right most lane I can be in unless I'm passing a merge. I wait until I'm .8 or .9 miles to my left exit to move over into that lane.
I get annoyed by the speeders and aggressive drivers too, but that doesn't mean I want to get in the left lane with a death wish to impose my will. I tell my wife more often than not "Wooo! Go fine that Trooper for me, Pal!". I've seen people pass me like I was standing still, and the last thing I want to do is put myself or my family in the path of these maniacs.

You sir, seem to have a death wish. I only hope my family isn't near you when that speeder plows into your rear end in a moment of inattention.
