Why didn't they utilize shopping carts and bicycles more?

Seriously, how is it that we don't see them riding bicycles more often? It's such a logical (and pretty quiet) means of transportation if you dont have a horse or gas. And I'm sure they could've found plenty in residental neighborhoods.

And then shopping carts could've been used for not only supplies but injured group members too. Or like the collapsible stroller wagons for kids. And they can pull carts or people on a bike too.

Lol I think of the scene in "Beautiful", Minnie Driver pushing the pregnant woman in a shopping cart 😅
