<p>Most grad students live in Ann Arbor. Very few students commute from Detroit. I’ve known a few to commute from the western suburbs (e.g., Plymouth, which can be a 20- 25-minute shot on M-14 if traffic is OK), but to commute from Detroit you’d need to commit 2+ hours/day round-trip to driving; public transit options are virtually non-existent. It just doesn’t make sense to eat up that much of your day commuting when you’re a student.</p>
