My family had at least one station wagon--Jeep Wagoneer, Ford Falcon, Ford Ranch Wagon--for most of the 1960s and 1970s. I don't remember ever hearing a concern about carbon monoxide. When did this start being talked about?
but I'm remembering that concerns about it started coming up in the 1960s when vehicle safety regulations were becoming a thing. Sorry, I don't have a historical reference at hand.
