Let's define "slow" in the fast lane. Is it less than 10 over the speed limit? What about 7? I have found myself in the fast lane, slightly speeding yet some "brilliant" people decide to tailgate.

What will you accomplish? Naturally, I'm not pleased with your actions, so what incentive is there to move? I know I'm pissing you off, so in fact, you have GIVEN me incentive to continue my current actions.

I think people would find driving much less stressful if they got rid of the notion of a "fast lane" and look at all lanes as potentially the fastest. Find the path of least resistance...typically switching lanes.
