It's much more efficient to have brighter vehicle headlamps and reflective signage and road surfacing. You drive as fast as your visibility allows for stopping distance. When the visibility is poor, the instinct is to travel slower and pay more attention, which contributes to safety. Perception of safety is often not correlated to safety at all. Roundabouts are much safer and often more efficient than traffic lights, but drivers tend to feel scared using them, resulting in reduced speeds and much less injuries.

Highways here seem to be engineered for a presumption of competency that does not hold true (including the lack of sufficient lighting), especially when it rains. The crash rate reflects this.
