Here, chew on this VCers like Dave Cotter and Aunt Roady in Illinois ...........
(b) The driver of a 2 wheeled vehicle may not pass upon the right of any other vehicle proceeding in the same direction unless the unobstructed pavement to the right of the vehicle being passed is of a width of not less than 8 feet. This subsection does not apply to devices propelled by human power.
(c) The driver of a vehicle may overtake and pass another vehicle upon the right only under conditions permitting such movement in safety. Such movement shall not be made by driving off the roadway.

Well okay then. As of the beginning of this year it's legal in illinois. Good find.
Aside from all that, emissions is rather low on the list of reasons (like my safety) why I filter.
I didn't find Interceptor's stuff scary at all. The traffic is so slow there that it's probably no more dangerous than walking through a parking lot at Wal-Mart.
You want scary? Here ya go:
I do, by the way, have a better understanding of the complex flow of air around moving vehicles than you seem to. I also am not under the misguided impression that my "nose knows". I'm a chemist, there are lots and lots and lots of chemicals that the human nose has no ability to detect. Not that there are many "toxic" chemicals to detect in our modern automotive fleet.
As for filtering increasing your "safety", I have yet to see how making a line of cars pass a bicyclist over and over and over again makes you safer. It's more convenient but not safer.
Madness? THIS... IS... FILTERING!!!!
Cyccommute - in my neck of the woods I'm being passed by a constant flow of cars. Whether the same ones pass me several times or not, I'm never at "the end of the line".
