<p>I don’t imagine this could really be a feasible or desirable option. Detroit-Ann Arbor is not an easy drive and not one that would be desirable to make on a near daily-basis. That being said, I’m not sure exactly where graduate students tend to live, so maybe some of them do make this commute. In my experience, though, Detroit to Ann Arbor takes much longer than 45 minutes and is a hassle.</p>
