#3: Sitting in the passing lane or HOV lane on an empty freeway doing 10 under.
WA is the only place in US where the rightlane moves faster than the left lane.

I drove all over the Western US last summer and EVERY time I encountered some Assh*le camped out in the fastlane with his cruise control on set at 10 under the MoFo had Washington plates.

I encountered this mainly on I-5 and I-90 North of Eugene and West of Missoula, but ran into it in I-40 in AZ and I-15 in CA as well as I-80 in Wyoming.

And yes, those same F*ckers have the "Self Appointed Traffic Cop" attitude of gunning it anytime you try to get around them.
