Here in the US, fog light lenses spread the light wide, almost 90 degrees to the direction of travel.
Driving lights are more like high beams. Both are supposed to be aimed. At 25 feet, Fog lights should
hit a vertical wall 4 inches below their height measured from the ground to their center.
Driving lights are supposed to be aimed 1.5" below their height from ground to center.
I would guess that most of the annoying lights you see are people that slapped them on the guard, and
didn't bother to properly set the lights at all....
