> Rate of speed is irrelevant.
Rate of speed is relevant for two reasons. First, there is a posted speed limit. Second, kinetic energy is proportional to the square of velocity. All else being equal, an accident at 90mph is going to be far more dangerous than one at 60mph.
> If you are not actively passing a vehicle, you have zero reason to be in the left lane.
The scenario under discussion was all lanes of traffic driving steadily at the limit. In such a scenario, you have zero reason to need to pass anyone. Surely you must agree that all lanes driving the limit is better than forcing everyone in the left lane to move over so that a few people can drive in excess of the limit? Having all lanes utilized at the limit is clearly the most efficient way to generate the most traffic throughput.
> Nevermind they are the most dangerous person on the road as people blow by them in the right lane rightfully pissed off.
Wait, so you're saying it should be acceptable to blow past someone who's already doing 8 over the limit? What are you thinking of, 15 or 20 over the limit? That's ridiculous, you have no "right" to be be rightfully pissed off because you can't drive 20 over the limit!
