We can barely bring ourselves to write about this excruciatingly uncomfortable incident in Berkeley, in which, to our dismay, bicyclists successfully provoke car drivers into behaving very poorly indeed. Who's at fault here? Unpleasantly, nobody seems to be able to agree. Cars, with their bulk and speed, are generally are viewed as the bullies in these sorts of situations; but like in that scene in Arachnophobia when the spiders crawl up out of the shower drain onto the lady, there is power in numbers. Did the Critical Massers use that numerical power for good or for evil? Perhaps you'd like to furiously scream your opinion in the comments.
