The model for banning cars from cities is either establishing a car-free core of less than a square mile, or establishing "superblocks" where car travel is only allowed on the perimeter of the block. Exceptions are made for deliveries and emergency vehicles, sometimes public transit, and sometimes resident street parking. So, the answer to all of your hypothetical scenarios is that they drive. And then possibily walk the last bit, less than a quarter-mile. I don't own a car, even though I take long trips regularly. I go hiking about 100 miles away once a month or so. (Rental car split with friends, generally.) I travel 300 miles about every two months to see family. (Overnight bus for a long weekend, generally.) Buying a car would be an awful financial decision for me. Not having to use a car for day-to-day trips saves me money and peace of mind.
