This strikes me as incredibly dumb from a safety standpoint, especially when it comes to motorcyclists. When painted parts of the road become wet they're slick as ice. Motorcyclists quickly learn to avoid a variety of operations on painted sections of the road, especially in the wet, because the grip is severely compromised.
