Do you have kids? Have fun moving them around without a car.
I have lived in cities where I _needed_ a car to do anything or wait for hourly buses + walking several miles.
I've been living in a city where I just use public transport (with a baby + wife) and I have only rented a car twice in 3 years, once to do a house move and another time to visit friends in a remote countryside location.
Demand more from local governments or move to a location that provides adequate transport as a service.
