Did food delivery for a while (Circumstances) last year, trying to find houses in the dark (Google Maps doesn't show newer address's well, or has the location wildly inaccurate).
One person in the near dark of her corner bi-level home decided that Numbers shaded in with pen in the window nowhere near the door was sufficient signage.
She did not respond well to "I'm driving in the dark, in snow, -30C outside looking for a house number (Nowhere near a street light & most people put on the door\exterior lighting if waiting on food) a window just below the roof is not a place I would be looking".
Oh & those that think rocks with the house number on them, angled up at 45 degree's & covered in snow are helpful.
Oh & those house designers\developers that use a black & metal house number plaque as signage, with lighting that brilliantly washes out the number in the dark or is not illuminated at all.
Biting the hand that feeds IT
