Parking Lights

Is it just me, or do others of you get really annoyed when you see someone driving in the early morning, or late afternoon with their parking lights on instead of their headlights? What's up with that? Why do people do that? Do they think that is what parking lights are for? Driving at dusk and dawn? I mean, do they not comprehend the term "parking lights", or do they unaware of the term "parking lights"? And why is it that many of those who do this are driving grey or sliver colored cars that are hard to see at dawn and dusk?

More annoying that this, though, are those that drive with no lights, parking or otherwise, at dawn and dusk. Again it seems that the drivers of grey and silver cars are the main culprits. Anyone else notice this? Maybe it's something in the grey and silver paint.... What do you think?
