I think we have different grocery habits.

Food, beer, and cat litter would be too heavy for a bike.

You don't think a family of four buys 'food' ? I also get beer occasionally, although sometimes I get it from the corner store a few blocks away.

I do get kitty litter with the car on the occasional trip to Costco because I'm not set on using the bike for every last thing. Just that the eBike makes a lot of things a lot more convenient.
