One thing I wonder about...  If the idea is that you live without a car until you need one for a trip or whatever and for that you rent a car, how does one get a driver's license when you don't have a car to learn and practice on?  My adult millennial daughter is in this exact situation, living on her own without a car - or a driver's license.  A driving school will only get you so far, to get a full Ontario G license you really need to practice driving for a long time and for that you need a car.  Without a car or driver's license my daughter has to depend on others for just about any travel outside her immediate transit area.  Heck, do car rental agencies even rent to anyone without a full unrestricted G license?
