I did, but I think that’s an English language issue. Apparently, by “keep windows down” they have meant “keep them shut down”. Completely counter-intuitive to me, vast majority of car windows move the other way, down to open, up to close.
I'm not sure I follow: in both the title and article, keeping windows down means allowing air from outside through the windows, no? Surely closing the windows cannot expose one to more air pollution than opening them?
