OK, so on another thread there's a discussion of when inside sun visors first came into use in automobiles.
There's a comment about the industry realizing the public wanted more enclosed vehicles, from a comfort standpoint.
The first enclosed automobiles (coupes, sedans) were late oughts or early teens, correct?
The question is, what year did production of closed cars equal, or exceed, production of open cars?
It would be interesting to know either overall, or by specific make.
