Here in the UK it depends what delivery service you're using. Supermarkets have a dedicated team of staff who organise approximately 45±10 deliveries per van per day. One store I worked for had 21 vans.

That helped save the journey of approximately 900 people. I think most would agree having 20 vans on the road is preferential to having 900 cars.

On the flip side, we also have services which deliver from small local shops and get basic shopping supplies to you within an hour, and these are far less efficient in terms of their footprint.
