Yeah plenty of people neglect to turn on their headlights in hazardous conditions. But I think that’s a result of too many “safety” features in modern cars! Think about it … if you have daytime running lamps AND automatic dash illumination, you have no unambiguous visual cues to remind you to turn on your headlights! You can still see the instrument panel, and there’s just enough light ahead so you can kinda see the road.
I noticed the automatic dash illumination thing when I was a teenager in my friend’s 1985 Grand Am. Made it impossible to convince him that he’d forgotten to turn on the headlights. The other problem was that the steering wheel blocked the view of the speedometer between 30 mph and 80 mph due to crappy design. Likewise made it impossible to convince him that he had to slow down on winding roads.
