> How do you think the groceries got to your shop in first place tho?

Through economies of scale with a truck delivering tons of goods while consuming more than the single-person car delivering it... I think it was pretty clear from my comment the excessive part is the "individual" aspect.

> Getting groceries for family with a bike would be somewhat insane for me. Technically possible, practically nightmare. Also much more expensive than driving for 10 mins to a larger shop.

Insane how? There are cargo bikes, you don't need to shop groceries for the month if you can bike there, you can do it every 3-4 days. I pack groceries in a cargo backpack, and they last 3-4 days, with a cargo bike it would be even easier to carry more.

It's only insane if you've never done it, or live in a place where frequent trips to a grocer takes 10km.

> You can use it for other things too. Taking kids to schools and hobbies, going to beach, city, forests, camping.

Use it for other things, not grocery shopping. Saves on excessive trips at least.

And a last disclaimer: I'm originally from a country very Americanised where people drive to go to the bakery, people there also think it's insane to do simple things on a bike (like grocery shopping) simply because the culture is car-centric... It's not that hard if the urban design where you live is not abhorrent.
