Except that if you cycle on a pavement at or below walking pace you
have more control over your bike, you take up less space, and you
shield pedestrians better from the oily bits than if you push the thing.

Well if you want to be "THAT" practical maybe couples should walk single
file to maximise the amount of pavement area available to other
pedestrians.
