There are many families with two cars that could drop to one car plus ebikes. The things you cannot do on an ebike can be done on the car that remains. It requires some coordination of trips because you can't just take 'your car' when you want to go someplace that needs a car, but most families are rarely in the situation where they have two such trips at the same time. YMMV of course, but if you are car dependent there is still a good change you can be a one car family.
