Tradespeople, they generally own their own tools and bring several boxes to even a basic job, plenty of jobs where you don’t need a dedicated truck.

My time in Paris was before we had kids, so I don’t know about the logistics there, but in NYC where I did not even think about owning a car for years it’s Very difficult without a car, and there are no more than a few neighborhoods with everything is actually available locally.

Also anyone just starting their business who doesn’t have a purpose built vehicle yet - breaking into catering, flower shop, etc.
