Partially incorrect.

True, you aren't as nimble in a car as you are on a bicycle. False, that you have to be senseless to deal with other drivers. Perfect examples: Avondale on ramp to 520 westbound, and Woodinville-Duvall Road at 156th. In both places, after the light the road narrows from 2 lanes to 1, with the right lane having to merge left. Every day, there's the same lineup of a-holes who zip up the right lane, get stuck at the light, and then lay on the horn when no one lets them merge in. Hrm, if you know the right lane disappears, maybe you should move over earlier instead of being an impatient, self-important prick who thinks they deserve to cut to the front of the line.
I see it on Avondale (eastbound) at the Novelty Hill split; people flying up the left lane of Avondale only to slam the brakes and cut people off to get onto Novelty Hill Rd, rather than just positioning themselves in the right hand lane to begin with.
My favourite example: I-5 south entrance from 520 west, trying to get to the Mercer St. exit during rush hour. People try to shove and muscle their way across 5 lanes of traffic in 0.5 miles to make that exit (the 520 ramp comes onto I-5 at the left-most lane). When they could easily take the street exit before the highway entrance, cross over the highway, and then take the ramp back onto I-5 south and be in the correct lane for the off ramp.

Any of that sound similar to the lane positioning that many of us do on our bikes, to make sure we aren't getting squeezed into a curb or fighting our way across dangerous intersections?
