Night driving is made harder by:
People with dirty and poorly aimed headlights.
Houses with exterior floodlights aimed to light up the air.
Buildings with bulkhead type lights that just throw the light
everwhere. Cyclists who deliberately seem to aim their intensive
lights at the eyes
of drivers.

And cars with LED headlights.


Cars with normal bulbs replaced with LED are the worse as the LED light
source is not quite where the filament was. Therefore there is some
scatter.
Dirty lenses also scatter the light.
