Chicago: 3.3 homicides (north side) + 5.2 traffic = 8.5
Fairfax County: 1.4 homicides + 7 traffic deaths = 8.4
If you're white or asian and don't drive in Chicago:
Chicago: 2.5 homicides + 1.1 pedestrian deaths = 3.6
From the yuppie perspective, the scary thing about traffic deaths is that you can't buy your way out of that risk the way you can buy your way out of crime risk. Your middle class teenage kids are highly unlikely to be the victims of violent crime, but are a major portion of the body count of driving deaths.
