I generally agree, though ...

> At least with delivery robots people don't have to take a one ton metal box everywhere with them just to get groceries because they live in a poorly designed car-centric city.

Robots are not needed and do not enhance grocery delivery. The ones I've seen aren't large enough for a grocery order. I suppose it would be entertaining to see a line of them proceeding to a delivery.

Okay but if they're delivering take out the benefit is even greater - mobilizing the 1 ton metal box to get a take out order is even worse economics.
