In both suburban(+rural?) and city areas, I hear a lot more of people racing their cars and honking lately. I suppose it is how they deal with their stress, by ignoring the needs of others as they think only of themselves.

Even if the former stuff is not the actual and literal cause of sleeplessness, I do find it highly emblematic/symbolic. People get theirs and everyone else can deal with it as best they can, or not, whatevs.
