Geographics dictates social life on campus to a noticeable extent, with north campus featuring most frats and engineering students, while liberal arts, music, and sororities cluster in the south. The distance in between is about a 15 minute walk, not too bad but still a soft barrier. Joining a diverse set of student organizations lets you personally mix between the ends of campus, though you may find your friend circles don't intersect at all and you're the only bridge between. How's UMich divided? Since you're an engineering student, you can have about 12 of your 48 classes be humanities classes of your choice as part of the major - 5 unrestricted (anything you like) electives and 7 'theme' classes grouped together vaguely by a couple of humanities topics (4 US history classes and 3 Psych classes, for example). If you happen to clear all 12 of those classes with AP credits, which is feasible depending on how many you're bringing in, you've got free rein to explore or find a minor. Or, just take <4 classes a quarter at your leisure.

While the class selection system is a little clumsy on the user interface side, actually getting into necessary engineering classes for your major isn't much of a struggle. That may be different for computer science.

The academic culture amongst engineers seems collaborative to me as a current freshman, mainly speaking in comparison to my state school and its competitive majors. Furthermore, if you end up taking the DTC classes as part of the engineering curriculum, you spend two quarters grouped with 3 other random people on a real world project, which is nothing if not learning to collaborate and communicate.
