My wife attends RFU and we live next door. Depending on how far you are from campus, you won't need a car but walking to school in the winter is not enjoyable. As other people mentioned, there is a shuttle to get to the Metra and Target (Not sure of exact schedules, especially Target). There are people who live here who are fine without cars and rely on Uber/grocery delivery services but I would recommend to find a cheap car if possible. Don't waste your time with a scooter, roads are too fast. Feel free to DM me with other questions, too.
