My thought: a common meme is that lax auto emission regulations hurt the poor the most.  Actually, the bigger effect on the poor is that strict emission standards largely make cars unaffordable for the poor.  I suspect they then become pedestrians or bicyclers, getting struck and killed by automobiles in numbers that dwarf the number dying from lower air quality.

At least pedestrians and bicyclers have less vehicle movement to worry about in some impoverished regions. In parts of Senegal the trucks are so outrageously overloaded that they frequently lose their cargo several times in the course of a trip. Yet a driver with a couple of tag-along hands often have plenty of time to restack it on the bed before such an incident ever becomes much of a traffic obstacle.
