Remember also that with AVs, vehicle design can change to accomodate multiple users on the same trip to the same "supermarket" in your example, thereby driving down the cost of operating the AV to the supermarket owner.
Regarding supermarket margins, you might be surprised to learn that UK supermarkets today have very high margins compared to, for example, US supermarkets (4% vs 2% from what I have read), but even this margin assumption may prove far too low in future. Why? A number of supermarket companies are testing out the idea of a cashier-less store by using the same technology that AVs use on self driving cars---namely, apps and sensors. In such a store, when the shopper picks an item from the shelf and places it in a basket or trolley, the item will be charged to the customer. You simply would walk into the store, shop and walk out, all the while removing layers of costs for the supermarket. While this recent link does not mention it, robots could easily restock shelves reducing the need for human employees. Labour represents a significant cost of operations at a supermarket.

Rather depends on the country or region you live in I assume. Can Governments and Local Authorities adapt to the new reality coming. Can cities plan ahead or will they always do the "knee-jerk" thing and just tax a new idea? Can cities make up for loss of road tax revenues or congestion charging or as Jokester suggests, electricity tax, in a world of zero- emission EVs that are AVs?
I believe we can redesign cities around technological breakthroughs such as AVs. See the link below for example in what Sidewalk Labs and the city of Toronto are planning for Toronto's Waterfront area. If land used today for parking spaces on streets or in car parks for example can largely be eliminated by AVs that operate as ride-hailing, app-obtained services that are in constant motion when not being recharged, can cities derive revenues in change of land use to offset lost revenues from road taxes or congestion charges for example? Sidewalk’s ambitions for its Toronto project include innovations that allow for more affordable housing stock, connected transit systems, environmentally-friendly and sustainable resource consumption, and data-driven community services. Surely there is scope for replacement revenue for Government.
