As much as I love college campuses, I think they often miss out on having interesting amenities within the walkability of the campus itself. Still, going to school in Cambridge I never wanted a car and the few times I rented one for a longer trip or a move I wished that I didn't have to.
I think cars are and probably should be convenient for certain things (mainly moving, buying furniture or other big stuff, and to a lesser extent getting into nature). But for day-to-day life, it is a sign of failure (and wasted potential!) when cars are convenient.
