Then public transport infrastructure isn't good enough. Also things like shop locations, e.g. noone is going to haul beverage crates in a tram so there's got to be stores with a proper selection within handcart to cargo bike or bike trailer distance, same goes for parcel pickups. And the roads have to be designed so that people feel safe using those methods.

I'd even go so far that in the vast majority of cases where you'd need a motorised vehicle you then want a van, not a car.
