I was thinking of parcel deliveries. Narrowish European inner city streets are regularly blocked by delivery trucks and fundamentally it's unnecessarily many of them because there are so many different companies servicing the same street. Where I live double parking on bicycle lanes is extremely common (the individual delivery people often see no alternatives), which poses massive dangers to cyclists. Also these trucks typically are quite large, worsening all issues, because a full load is meant for a long route.
If there was just a single company responsible for some "last mile" area, smaller vehicles like this electric model [1] would suffice. They would distribute parcels from a depot that is filled by larger long distance trucks that do not need to belong to the same company.
The last point is important: If DHL, FedEx, UPS etc. each have their own final storage buildings and delivery fleet, those depots could not all be situated close enough to the target addresses.
