Minneapolis which apparently is ranked on a international level, whatever that is supposed to mean has a mix of either your roadie spandex person or the average Joe clothes going to work. I mostly see backpacks and messenger bags on my commute and I am in the very central part of the city, as I move along to more "ritz" area's of the city I notice more panniers and bikes built for purpose. I do not live in this fancy areas but I do use a pannier and ride a Surly Ogre 99.9% of the time all year with fenders etc. I also do not ride in spandex to work I usually have specific clothes I do wear but most of it is wools with no real logos or big flashy stuff.
On Minneapolis it is true we do have a big cycling movement and I am sure a lot of the people who are from here can tell you that but really anywhere outside of the city it is about as good as the worst cities in the US there is just not really any infrastructure even within the same county(Hennepin), it is all within the city limits where you see it.
On the world scale I have a lot of friends from South America and the infrastructure and thought of cycling is even worse than it is here. Sometimes I get a friend from the Netherlands who visits me and it is nice to talk with him about cycling or hear him talk to one of our South American friends about it, they are so polar.
