First of all, glad to hear that your skills and your guardian angel got you thru that event. Regarding your exhaust comment, I have to say that I really don't think that makes a difference in most cases. Inattentive drivers are oblivious to nearly everything. I have had people pull out in front of me, and/or not pull over when I am driving a firetruck with all emergency lighting on and siren/air horns activated. Some people are just clueless and shouldn't be driving.
