UK is a case scenario, one grocery store started offering online delivery of groceries.. then all the rest had to offer it to compete, and now its killing the box stores and they have no way out as everyone moves to get groceries delivered.. grocery stores hate it and would take it all back if they could.
used to be 90% of the transportation cost was the last mile delivery and we took that upon our selves, now w/warehouse automation and upcoming automated delivery capabilities its gonna change our cities quite a bit I suspect; think of all the acres of parking lots that'll soon be reclaimed and repurposed and giant parks we can make of those defunct malls.. gonna be painfull but its progress.
