I guess the problem is that you don't have a minority group you can blame it on. The smokers in my department have to go outside to smoke. That's not just because second-hand smoke is dangerous, it's because there are enough non-smokers who don't want smoke around them that they won out over the smokers.
Unless we think pollution affects us enough individually to cause us to take responsibility, we'll keep tanning the inside of our lungs with car exhaust.
