A good solution for that is probably to remove the foot paths on both sides to add 2 more lanes for traffic, that way everybody can just get the stuff they want delivered from the shops and there would be no need to actually walk in the area thus also speeding up traffic flow. Win win.
If any bit of Oxford st is pedestrinised won't food delivery riders just hammer through in their usual not give a fuck fashion?
Not a for or against arguement, just that's whats gonna happen.
