I was just thinking - why don't they make electrified coin-operated shopping carts that you can take home and return when you're done with them? That would greatly extend the carrying capacity of a single person and maybe make car trips redundant.

Because nearly no-one wants to walk to the store, walk home, walk back to the store to return the cart and then walk home again.

I never drive to the store and I still wouldn't do that.

You'd keep the cart until next time you need it.
