There is an inherent wrongness, especially in cities as crowded as Sydney or Melbourne, that a person in their own metal box should be able to poison the air of another, to commandeer resources and space from another walking or riding a bicycle, simply because they feel better, or safer doing so.

Yes people perceive that they are safer in own security cells (clearly the writer has no grasp on road fatalities), but other people suffer serious lung damage from tiny metal shards released by those little boxes. With all the fuss about smoking, private vehicle pollution is a wrongness that we've long neglected to fix.
