I live on the edge of the suburbs in a Blue state, at least where I live (and further on towards the city) open carry gets you the attention you're looking for from the police. People don't tend to do it.
I am not sure about further out. I know people in Michigan who keep a piece in their glovebox. I've seen in the movies what you talk about - the gun rack in the truck cabin. None of my rural relatives ever did that, not even in Michigan which is pretty gun-friendly away from cities.

Yeah, I mean. In Illinois at least, the guns get into the hands of the bad guys overwhelmingly because of straw buyers. Not because of "the gun show loophole". A small number of guns are obtained through theft. Mostly it's straw buyers, at least when it comes to guns used in crimes.
My family is filled with outdoorsy people (myself included), and although the numbers don't paint a picture of legal CCR owners being problematic, the wide array of people I've known who do carry makes me wonder how the hell it isn't a bigger problem. All manner of unhinged weirdos, some of whom pretty openly muse about the opportunity to shoot the kind of person they don't like. (Lots of normal people too - but plenty of weirdos)
