I put three through college. Putting going to and from home aside, they all needed a car.
Trips to WalMart, maybe 4-5 miles away? Doctor or dentist visits, attend Church, clothing store, shoe store, torrential rains (or high winds, bitter cold, whatever) and next class almost half mile across campus? Then, occasional evening out for a movie, dinner or college ball game? Endless things could call for the need of a car. I always taught mine to be self sufficient, don't beg or depend on others for rides.
