I believe the problem with drivers not using their headlights is a technology issue and also moron related. Cars today have an instrument panel that lights up as soon as the ignition is turned on. When it is dark, they see their dash all aglow and mistaken believe they are alight fore and aft. Also, some day time running lights can give the illusion that the car has headlights and tail lights, in reality only the DRL are illuminated, on rear lights. Technology can't completely eliminate the moron factor.
