In what kind of context? This isn't something I hear used in normal informal speech, except for a few sentences like "what to do now?". It may depend on dialect as well. I speak mostly British with some American influence.
I wouldn't say there's something wrong with this kind of sentence, it just doesn't seem so natural to me.
I'm not sure if it should be accepted or not, but it is typical to say "Where can you ..." instead of "Where can one ..." (to generally mean "Where is it possible to ..." or "Where could I ...") in colloquial American English. "Where can one..." sounds formal or British to me.
