There is a great scene in the movie Crocodile Dundee where he is walking down the street in Manhattan, tipping his hat and saying "G'day" to each one of the millions of people he passes!
I know that doesn't really answer your question, except maybe to point out that the norms of acceptable behavior depend on the culture and context. A small town will have different social expectations than a big city, for example.
Exactly and the result of Dundee getting it "wrong" for New York was lots of people felt nice because a stranger had smiled at them in their cold city life. Dundee was the loveable maverick hero.
You should look wherever you like, its your world. You should be kind enough to care that you don't barge into people, dont knock fragile old ladies over, and be ready to help a mum struggling with a pram. Otherwise do whatever you want whether its "appropriate" or not.
People are going to be lifted by a smile, if its genuine. Use it as a default as often as you can enjoy doing it (but maybe it stresses you). If getting a situation "wrong" means people misunderstand you as being rude, thats a shame, but if getting a situation "wrong" means you look me in the eye and you are the smiley friendly person, that would just warm me to you.
