Are you that obtuse? You exhale entirely out of the window? Ask your kid (if they can speak over the wheezing and asthma) if they can smell your cigarette smoking when you are in the car. If they can smell it, they are inhaling carcinogens.
“If they can smell it, they are inhaling carcinogens.”
Since you have made it clear that you are in support of the government regulating adult behaviour that causes children to be exposed to toxic substances and carcinogens, at all levels, is it safe to assume that you support this in all situations?
Would you support the government regulation of cleaning supplies used in the home? How about just allowing the police to ticket people for cleaning with toxic chemicals while their children are in the house and can smell the cleaning chemicals?
