Padding things: Does not scale

The subject of this article padding lampposts to prevent injuries by people walking into them. From an engineering standpoint, this does not scale. Padding only some items will not negate people's need to consistently watch where they're going. Padding all the items will be prohibitively difficult given pedestrians and cars travel in the same area and cars will require significant volumes of padding to make them pedestrian friendly.

The solution does not scale.
