The Norwegian Public Roads Administration have to do a bit more than patching potholes and applying overbanding, here they're using a helicopter to eliminate a rock fall hazard for the road below. Later you can see just how effective the catch fencing is.

The helicopter then drops water on the rock face, at Oppdølstranda on Nordmøre, to loosen and remove any remaining smaller rocks that may fall later.

They may be smaller - it's hard to judge scale in such an amazing setting, but I reckon even a 'small' rock could waste your Volvo and seriously ruin your day.
