so cyclists do not need to whinge about it as they have less of it to
breathe than car drivers suffer.

That's a bit like saying that passive smokers have no need to complain
because they breathe less smoke than smokers.

IIRC, there was a 40-year study carried out in America that followed the
lives of 100,000, or more, couples - where one smoked and one didn't,
comparing them with couples where neither smoked, and that it showed
that the non-smokers living with smokers showed an insignificant
increased risk of developing a serious smoke-related illness over
non-smokers who lived with non-smokers for the same period.
