Headlights.. Daytime

The other side of the coin, and I've done this before, is that people who are not that familiar with their vehicle driving with DRL, never bother to turn on their lights, thus they are running without tail lights. I see it all the time.

Also, a big part of my commute is at highway speed near a river. At certain times of year headlights guarantee that you'll be spending a long time removing bugs from the windshield and grill. In our case, there's enough bugs to render the windshield almost dangerous.

This is true, I see it as well and I think that is why DRL's are evolving. The new LED systems don't provide enough light to illuminate the road but do make you visible to other cars, cyclists and pedestrians. If you actually want lights to see anything, you have to turn your headlights on. They also also use a small fraction of the power that headlights use.
