I can only respond to my own observations, and they are that it is common to get an evasive answer to the question, for a variety of reasons, some of which - like David's prior comment - I would not have expected. As for the thought that I am being sarcastic, the situation determines the response. "Often" doesn't mean "always" and "often" is usually when you're stopped at a light and someone hollers out from another car or the sidewalk. On those occasions, the person asking really doesn't care, so they get a response that says neither do I.
