I was saying why those in cars were not affected by this. The filters in modern cars a designed to remove most of the stuff from the air coming in the car. This is something extra those on bikes don't get. I imagine you could see smiler things happening to those on motor bikes and people who keep the tops of convertibles down in the city.

But yes, you won't be breathing all the same crap sitting in a car with the windows up.
