It just seems like a car is the wrong form factor for all of these tasks. Or more importantly, doing all of theses task atomically using cars as the atoms is awfully inefficient and cumbersome. So much capital and physical resource goes into manufacturing cars, and to then use a lumbering metal cage to pick up groceries when transporting a human is no longer a requirement seems silly.

There is also the issue that car infrastructure dominating humans living spaces and running out of space has become an increasing issue and EV/vehicle automony only embeds the issue deeper into our societies practices. We should be finding ways to replace cars.

Disclaimer, I come from rural South Australia and would have found it very difficult to live without a car due to the long distances involved and complete lack of public transportation outside of the (only) city center. So I empathize with the rural need for cars. But the majority of people who would buy an autonomous EV are not going to be rural, and probably have better alternatives.
