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.
I love how that clip has multiple shots of trucks absolutely full of boxes, while making the case for a vehicle that could fit inside the truck as it's replacement.
I think you just missed the point entirely. You don't actually have to load up as many items in a cargo bike, because it's inherent advantages in urban contexts more than makes up for its inability to load up as many items.
If I own a grocery, it's going to take a hell of a lot of bike trips to and from the warehouse to restock every day. Or I could employ an army of bikers. Or one truck.
Ok, so deliver food via truck. Choose the appropriate means of transportation for each type of last-mile delivery. The 200 gram Amazon package most certainly does not require a heavy truck to deliver.
It seems I missed the point. I had deliveries in mind where the truck is mostly empty most of the time. Restocking with a truck or cargo tram (depending on the environment) would make more sense.
