I'm not looking to ditch the car and replace it with a cargo bike, Toronto's inter-community transportation network is not up to par for me to consider it yet. However in my immediate neighbourhoods a cargo bike could allow me to park my car and keep it parked.
While mapping out my "community cycle circle", I've confirmed that everything I need to fulfil a simple yet social life with my family and children resides within a 5km zone. I do not need a car to get the Food Folks and Fun.
My wife seems to think this could work.
