I can only imagine that these people complaining about everyone doing that are themselves the people who do that.
Why would you assume that? "He who smelt it dealt it"? As an observant driver, I notice this phenomenon because it creates a "channel" of other cars moving around me. This is hazardous because it involves a lot of unnecessary passing and lane-changing.
Probably also the same assholes who know there's going to be a long line for the ramp and, rather than getting into it and waiting their turn, stay a lane over and then try to merge in right at the end.
Well, thanks for the vote of confidence. This is something else that I see regularly at I-290 for the offramp to I-90/94. Actually, on this topic, I do have a pet peeve. When "merge ahead" signs are posted for construction, many drivers will merge shortly after the signs. However, if the signs are posted too far in advance of the actual merge, this results in some drivers merging too early, and other drivers seeing the opportunity to "jump the queue" and drive all the way until the merge point. If everyone stayed in their lanes until the merge point, there wouldn't be a moral hazard to jump the queue, and traffic flow would probably be improved due to an orderly "zipper" merge. But once an early merge has started, only an asshole will break the unspoken courtesy-merge and continue straight until the actual merge. All because the signs were so early.
