> Drive-thru supermarkets/walmarts/amazon pickup is going to change the world.

you probably mean change the USA, in France for instance, drive-thru supermarkets exists since at least 5 years [1][2] They now even have some new 24/7 pick up locations, which is a big deal for France where there is no 24/7 stores. There, your food just waits for you in a refrigerated/freezer lock box [3].

I'm actually surprised this is not already a common thing in the USA, which invented drive-thru fast foods 70 years ago.
