And, whatismore, the smoke from tobacco is a natural substance whereas the fumes fron vehicle exhausts contain not only solids but some wierd chemicals as well. And passive consumers of it have no choice which is not the case with tobacco smoke.

The "Great Victory" was to get tobacco advertising banned. That brought the whole of Media onto their side because it could no longer make money from tobacco and any money spent on tobacco was not spent on products Media could get a cut out of some of which involved passive welding, passive timber machining, passive sofa stuffing etc etc etbloodycetera.
