Has anyone ever done any sort of analysis to measure toxins from cars on a typical restaurant patio vs. those produced by smoking?
I have done some googling and did find a reference, but it was measuring the amount of CO produced (it found that most cars produced it in far lower cncentrations than cigarette smoke. Nothing about other chemicals though.)

I suspect that the fact that risks from car exhausts would be much less than for cigarettes (either indoors or on a patio) for a couple of reasons:
- Even though a patio might be close to a street, there will likely be at least a couple of meters separation; compare that to a smoker who might be sitting only a few feet from a non-smoker.
- Even on a windless day, the cars themselves would be causing a disturbance in the air, enhancing dispersal; compare that to a smoker, who's likely just sitting there.
I think we can wind back and take a bird's eye view of the question... if adverse reactions are an indicator of intensity (which I think is a reasonable assumption), then it's clear that the concentration of irritants in an enclosed smoke-filled environment are comparable to only the worst environmental pollution. Levels that haven't existed in the West for decades.
It was relatively easy politically to pass EPA (or here it's Environment Canada) regulations to curb industrial and vehicle emissions. At this point, we're at a more politically difficult moment where we're trying to regulate air quality in privately owned environments.
