sidezoomer
n.— «Sidezoomers have a variety of strategies, each exaggerated by the configuration of the Caldecott but replicated in bottlenecks across the land: there are the ones who zoom by a few dozen cars, angling in when they see a plausible opening; and there are the ones who zoom all the way up, to the very top of the cone-off funnel, at which point they thrust their aggressive little self-entitled fenders toward the lineup and nudge themselves in. And there are those who opt for frontage-road sidezooming, which requires maneuvering into the far-right highway lane in order to get off at a certain pretunnel exit that dumps cars onto a surface street alongside Highway 24.» —“The Urge to Merge” by Cynthia Gorney New York Times Magazine Aug. 3, 2008.
