<p>“Limited parking” has been said, about 10x already, but another reason I think is so that freshmen are kind of “forced” to stay on campus and learn the ropes of college. Leaving home can be an adjustment to begin with and I guess not having a car and not having to worry about gas, parking, security, is one less thing to stress about on top of a new college courseload/homesickness/new surroundings/etc.</p>
