Earlier quoted context omitted.
At least it isn't hazardous like cigarette smoke. I really wish cigarettes were completely banned in public spaces. If you want to destroy your own lungs on your own property, fine. But I shouldn't have to breath it in.
Add gasoline/diesel powered automobiles to that list please.
Fact is, cars have a lot of other utility, and if it was possible to make a car that doesn't make smoke cheaply and without any other negatives, the whole car industry would go that way, legislation would happen and no more smoky cars would be made.
Smoking however has no other utility beyond, "screw you, I smoke wherever I want regardless of others comfort/health, and if you don't like it then you have go somewhere else".
