Why do people drive at nighttime and turn on their running/parking lights, but
not their headlights? I mean, you've gone to the mental and physical energy expenditure to actually think about and flip the switch/pull the knob to activate some sort of external lighting system. When not go the extra 0.000005 calorie, and turn on your headlights, ya moron? (Reference: my son's favorite movie,
Cars.)
edit: And why is this in the Technical forum, when I tried to start it in OT?
