You bring up lots of good points. Just to clarify, this dude was not anti Cobras at all, in fact he likes them, he just thought it could be a health risk (while sitting in traffic, etc) because he believes that car exhaust, especially, untreated (no emission controls) is a carcinogen, so the more you’re exposed, the more chance of problems for you.

So, I guess the real question is, Is car exhaust a carcinogen or will it just kill you due to the CO content?  Come to think of it, we know gas fumes are a carcinogen, so I suppose if we fuel our cars ourselves, we have a great chance of cancer, then driving a Cobra because, all cars use gas. . . .

Thanks for all of the answers, I’m concluding that it’s just another one of those crazy things people say. . . . .
