What I assume "living car free" means that you don't own a car and don't use one for day-to-day life. If you rent one for vacations or during business trips, that's different. But for your own day-to-day life, if you ever use a car to get to work, take your kids to school, go out, visit (local) friends, get to class, go shopping, etc., you're not living "car free" as far as I'm concerned.
