Mmh in my experience actually not.
Very distinct streets in the centre are shopping streets (with residential on the higher floors).
Many neighbourhoods are just residential.
while you could argue the specialized electric buses and delivery vans are "Cars" they cannot drive on normal roads and do not produce pollution, in terms of emissions or noise, like regular cars. It's more than possible to build a car free city, its been done before.
but something like this would get product coming-in from outside a metro area close enough to high-density population and business centers to where smaller EV delivery vehicles or postal services (they already go door-to-door each day) can do the 'last-mile'.
