Is it OK to ask a general question like "How does one get to the city?" if you want to know how to get there?
How about this one. You want to ask how to get a driver's license "How does one get a driver's license?".
Using "one" sounds formal to the point of possible confusion. I believe it was a common way of speaking in the past, but it sounds quite old-fashioned now. Many people these days would have no idea what you were trying to say. As a clever man said, "If you use "one" like that, it sounds like you are too proper to have sex."
"How can I/do I/ do you/do people get to the city..."
Warning: the phrase "the city" can mean different things in different countries and different areas in each country.
