AA to Dearborn really isn't that bad. Outside of some construction in the DTW/275 area occasionally, it's not bad at all. I previously drove through there almost daily during morning/evening rush our times, and can't complain too much.
Althought living downtown sounds wonderful, I think I would take a 30 min trip twice a day, to ensure my car isn't stolen, I don't get stabbed, etc, but to each their own!
Good luck, and welcome back.
